Our lab undertakes research on adaptation of organisms (particularly invertebrates) to environmental stresses including climate change and chemical pollutants, using field sites in the Victorian mountains, in tropical rainforests and in wetlands around Melbourne. We also develop integrated pest control options, investigate how landscape changes can be harnessed to provide pest control services, contribute to novel approaches for suppressing dengue mosquito vectors, and examine new ways to predict species distribution shifts under climate change.
We focus on three main areas of research:
- Climatic Stress – to find traits that enable adaptation to climatic stress, and to understand the genetic basis of these traits;
- Applied – to develop better ways of sustainably controlling pest species important from an agricultural perspective.
- Applied – to explore new ways of reducing the transmission of human diseases by insect vectors based on endosymbionts.
In understanding the main issues and mechanisms involved with adaptation of organisms to stress, we are able to make informed management decisions to assist the community and industry.

My focus is on pest control & environmental stress adaptation. Undertaking research on invertebrates, developing integrated pest control options for the grains industries, investigating how landscape changes can be harnessed to provide pest control services & contributing to novel approaches for suppressing dengue mosquito vectors. We focus on adaptation to rapid environmental changes in a range of species, developing ways of incorporating evolutionary approaches when making predictions about adaptive capacity & when predicting species distribution shifts under climate change. We have expertise in genetics and genomics, pest entomology & physiological ecology.
Perran has been a member of the Hoffmann lab since 2012, where he previously completed a MSc and PhD working with Aedes aegypti mosquitoes. He is interested in disease control programs that deploy modified insects into natural populations and the factors that could affect their success. During his PhD, he investigated the effects of different environmental conditions on Wolbachia infections and the mosquitoes they infect. His current research will involve generating new Wolbachia infections in Aedes aegypti and insect pests to provide more options for pest and disease vector control.

Nancy Endersby-Harshman, Research Fellow and Laboratory manager
Nancy is a Research Fellow in the Pest and Environmental Adaptation Research Group in the Hoffmann Laboratory, Bio21 Institute, School of BioSciences at the University of Melbourne. Nancy has a background in horticultural entomology and a PhD from Monash University on the genetic structure of Australian populations of the horticultural pest, the diamondback moth, Plutella xylostella. Nancy currently conducts research on the dengue vector mosquito, Aedes aegypti, in the fields of insecticide resistance, population genetics, Wolbachia pipientis and vector ecology. Nancy manages the group’s Molecular Laboratory and the Arboviral Research Laboratory, a Biosecurity Approved Arrangement with the Department of Agriculture and Water Resources.
Our laboratory studies release of Wolbachia-infected mosquitoes (Aedes aegypti) to reduce the impact of dengue virus. Wolbachia-infected mosquitoes do not transmit dengue and we aim to replace the natural population of the dengue vector with the same mosquito species in which virus replication is blocked. The Wolbachia strategy relies on the released mosquitoes being fit and competitive in the field and different strains of the Wolbachia bacterium may have differing fitness costs to the mosquito. So, an important part of our research is to do with maintaining a high level of quality in our mosquitoes for release.
After Wolbachia-infected mosquitoes were released with success in Cairns, the program was mobilised with releases occurring in parts of Asia and South America where different levels of success in establishment of the Wolbachia mosquito lines have been experienced. Consequently, we now investigate environmental factors which may act as barriers to establishment of Wolbachia strains in the environment in an effort to find strains that will perform robustly in the field.
Current projects in this field look at
- effect of environmental levels of antibiotic contamination on Wolbachia-infected mosquitoes
- background levels of insecticide resistance in Aedes aegypti at potential release sites with a particular focus on pyrethroid insecticides and target site resistance
- Other insecticide resistance projects include assessment of resistance status of Ae. aegypti which arrive in Australia as exotic incursions in comparison with the local population of Ae. aegypti mosquitoes in Queensland.
Outbreaks of dengue fever have occurred in Queensland, Australia, since the late 1800s, leading to ongoing attempts to control the mosquito vector, Aedes aegypti (L.). Since the 1990s, pyrethroid insecticides have been used for this purpose, but have been applied in a strategic manner with a variety of delivery methods including indoor residual spraying, lethal ovitraps and use of insect growth regulators as larvicides. Separate selection experiments that we conducted on mosquitoes from Queensland, using Type I and Type II pyrethroids did not produce resistant lines of Ae. aegypti and bioassays of field material from Queensland showed only weak tolerance in comparison with a susceptible line. There was no evidence of knockdown resistance (kdr) mutations in Ae. aegypti from Queensland, in stark contrast to the situation in nearby southeast Asia. We suspect that careful management of pyrethroid insecticide use combined with surveillance and interception of exotic incursions has helped to maintain pyrethroid (and particularly kdr – based) susceptibility in Ae. aegypti in Australia.

Working with the PEAR group for many years now, I have both witnessed and participated in its incredible evolution. My work debut involved the miniscule but “mighty in damage” grapevine pest phylloxera and its plant hosts and I quickly learnt to adapt to large scale and often complicated (damaged insects and fibrous roots) genotyping. I also managed the Molecular lab for a short time and was instrumental in the development and implementation of training (equipment and procedural) and EHS practises.
It is fitting that after I became a mother. I returned to the group to work on “the Mother of all dengue vectors”, Aedes aegypti. Here I worked closely with an incredible and inspiring mentor, Nancy Endersby-Harshman, to develop and test genetic markers in Aedes aegypti but also Aedes notoscriptus and Aedes albopictus. Research applications for these markers included population genetics, phylogeography, phenotypic trait association and conversion to new technology platforms (for example, from the P33 radioisotope to the fluorescence based system for microsatellite markers).
Then an endosymbiotic bacterium called Wolbachia exploded into my working life and it was both incredibly promising in terms of its ability to block the dengue virus (and later zika virus) and complex because it was a “novel” vector control strategy with the option of multiple Wolbachia strains whose dengue blocking and host effects (negative and positive) varied. PEARG first focused on the Wolbachia strain wMel and a dedicated period of colony experiments, field releases, molecular testing and post-release monitoring followed providing us with a good understanding of its role in disease suppression. The PEARG captaincy by Professor Ary Hoffmann however soon added other mosquito hosts and Wolbachia strains into the mix and fine-tuned our research goals and approaches to better understand the genetic mechanisms both driving and confounding the spread of Wolbachia in natural populations.
My contributions to this “Wolbachia era” include screening of thousands of Aedes samples for Wolbachia infection status with established “high throughput” light cycler assays but also developing and optimising new light cycler assays including those that can detect very low level and multiple Wolbachia infections in mosquitoes and fruit flies. But by far the most rewarding experiences have been sharing these methodologies with visiting collaborators from China, Indonesia and Sri Lanka and my visit to the wonderful Institute of Medical Research (IMR) in Kuala Lumpur, Malaysia, where I helped adapt our procedures to their working environment. The importance of this IMR collaboration was further highlighted by colleagues who had been infected by dengue three and four times. A job that has the potential to help the lives of many people is something rare and special as is working for Ary, who believes in sharing and advancing the technology and resources that he and his team have developed to fight dengue where it is truly needed.
Recently I hopped over to grasshoppers: So far I have tested mitochondrial and nuclear markers on the parthenogenetic species Warramaba virgo (comprised of two distinct phylads, Standard and Boulder-Xanthus) and maintained a colony of and performed physiological trait measurements on Vandiemenella (another genus of Australian grasshoppers that is made up of different chromosome races). I am now learning about the fascinating Keyacris scurra grasshopper and its conservation plight that restricts it to a handful of regional graveyards. And I am also exploring potential next generation sequencing technologies that can be used to characterise the genetic diversity and evolutionary histories of matchstick grasshoppers (family Morabidae, comprised of over 300 species that do not occur outside Australia) and help identify threats to their future (for example, climate change) and practises that can reduce those threats (for example, translocations of individuals to threatened populations).
Keyacris scurra walks into a Melbourne Uni lab and the scientist says “Why the long face?” and she answers “Because I am at grave risk of extinction”.

Melissa’s main interests are understanding species diversity using DNA barcodes and developing DNA-based tools for environmental monitoring, especially in freshwater ecosystems. In the past, her research has largely focused on using DNA approaches to understand life histories, population structure and for species identification of various invertebrate (and some vertebrate) groups. During her PhD, she developed DNA approaches for species identification of Chironomidae (Diptera), well known as a bioindicator group in freshwater environments. She also investigated the bioindicator potential in particular chironomid species by examining their field-based responses to pollution. More recently, her work has broadened to include identifying many species of freshwater macroinvertebrates using DNA barcoding.

Garry McDonald, Research Fellow
Garry has been a research and extension entomologist with the Victorian DPI for 22 years, working initially on mosquito and ant ecology /management, and subsequently on integrated pest management (IPM) and biological control strategies for a range of pests of horticulture, field crops and pastures. Some focal pests of particular interest included Helicoverpa spp. (native budworm and corn earworm), Leucania and Persectania spp. (armyworm), Agrotis spp. (cutworm), pasture cockchafers, Nysius vinitor (Rutherglen bug) and earth mites.
Since 1996, Garry assumed broader administrative roles as Director, Rutherglen Research Institute, subsequently Research Director of DPIs Landscape Systems Sciences Platform, and more recently Director of Swinburne University’s National Centre for Sustainability. In this capacity, he was a Board Director for the Energy Efficiency Council for two years.
Garry joined PEARG in mid-2012 in a part time capacity to undertake research aimed at developing pest forecasting models for the key pests of the crop establishment phase of Australian grain crops – Halotydeus destructor (redlegged earth mite) and Sminthurus viridis (lucerne flea). The modelling focus on developing predictions of both the timing of outbreaks, and their relative severity. He is also the Executive Officer for the Grains Pest Advisory Committee, a national science advisory group for the Grains Research and Development Corporation.

Tom joined PEARG in 2014 to undertake a PhD, and since finishing in 2018 is currently employed as a research fellow. His research considers the invasive arbovirus vectors Aedes aegypti (yellow fever mosquito) and Aedes albopictus (Asian tiger mosquito), with an aim to understand how they disperse through anthropogenic environments. This research informs biocontrol efforts at three key stages: identifying invasion routes and source populations, estimating the potential for spatial spread of disease during arbovirus outbreaks, and designing strategies for the elimination or control of invasive populations.
PEARG has been central to the development of vector control strategies involving the release of mosquitoes infected with the bacterium Wolbachia, which leads to either local population eradication or the ongoing suppression of its vectorial capacity. Tom has been involved in these developments directly, investigating spatial dynamics of the three Wolbachia invasions established among Cairns Aedes aegypti in 2013.

Matthew Binns, Research Assistant
Matthew is currently working at PEARG as an entomologist with a focus on agricultural pest management. His background has been mostly based at the University of New England where, from 2008, he studied insect morphology and species diversity over climatic gradients. From 2012, Matthew shifted focus into agricultural issues where he studied attract-and-kill management strategies for Helicoverpa moths in cotton and diamondback moth in canola.

I have a BSc joint honours degree in Biochemistry and Pharmacology from King’s College, University of London and an MSc in Natural Resource Management from the University of Leicester, UK. I obtained my PhD in aquatic ecotoxicology from RMIT-University in 2001 where I investigated the effects of crude oil on octopus and mussels. I spent eight years as a terrestrial ecotoxicologist at the Centre for Ecology and Hydrology at Monks Wood in the UK, investigating the effects of pesticides and industrial contaminants on vertebrates and invertebrates using traditional and novel biochemical techniques. I am currently a Research Fellow at CAPIM and PEARG in the School of BioSciences at the University of Melbourne. I have supervised two PhD students (conferred in 2017), three Masters students and a post-graduate diploma student at the University of Melbourne. I am currently supervising two PhD students within the School of BioSciences.
My main research focus is to develop novel methods (predominantly metabolomics, proteins and enzyme activity) to assess biological effects of environmental stressors (anthropogenic and natural) in aquatic organisms. These methods can be used in biomonitoring programs alongside analytical chemistry techniques and community surveys to provide early warning indications of poor water quality to assist in the management of aquatic ecosystems. I am particularly interested in the interaction between stressors and organisms at the individual level to gain a greater understanding of the mechanisms of action of these stressors. This will allow us to better predict adverse effects of mixtures of stressors in the future. I am currently working on a project to develop novel methods of assessing pollution stress in estuarine environments using metabolomics and DNA metabarcoding in collaboration with Melbourne Water and CSIRO.

I majored in Zoology and Genetics with Honours at Latrobe University, Bundoora and the University of Melbourne. During my honours year in 2009, I developed skills in Drosophila melanogaster DNA sequence analysis and cloning techniques. My professional career began in 2010 as a Research Officer within the PEARG. My skills have expanded since 2010 to include insect husbandry (Aedes aegypti & Aedes notoscriptus), method design and fitness experimentation upon Aedes aegypti, the primary vector of the Dengue virus. The research aims to inform population dynamics models which predict the spread of released mosquitoes artificially infected with an intracellular bacterium, called Wolbachia pipientis, the goal being arbovirus transmission cycle disruption between humans. Other research has involved species distribution modelling upon Aedes albopictus, field work in Cairns and abroad, respirometry, elucidating the transmission cycle of Mycobacterium ulcerans and thermocycler heat stress assays.

Ary keeps me busy managing the lab’s business affairs, occasionally I find time to do a spot of research. I came to science a bit late in the game after several incarnations (audio engineer, archivist, landscape gardener, removalist, ward clerk, night clerk, risk assessor etc.). I completed a bachelor of biological sciences at LaTrobe in 2013, jumped ship to complete an honours year at Melbourne and managed to pull off a first class result under Ary’s supervision. I spent a couple years as a research assistant doing a mix of agricultural consulting work on the road and in the lab. I have a diverse repertoire of skills from bioinformatics to field ecology, lab assays and many points in between. Jack of all trades, master of some. Most of my functions these days are focused on running the labs business affairs, a complex and interesting area to say the least.

Kelly has an interest in disease and the roles animals and the environment play in disease transmission. She explored this as an honours student with the PEARG Mosquito Group in early 2008 where she investigated the thermal responses of larval mosquitoes and the influence of climatic changes on their microclimates and potential range in Australia. Since then, she has spent over seven years working with PEARG on a range of projects including the fitness of Aedes aegypti mosquitoes with Wolbachia, the resistance of various wheat lines to the wheat curl mite Aceria tosichella and the wheat streak mosaic and high plains viruses of mites and wheat plants. Since October 2013, Kelly has worked on detecting and characterising Wolbachia in a diverse range of Drosophila species from around Australia. She has detected a number of interesting strains including some male-killers!

Yang is currently working at PEARG as a population geneticist with a focus on insecticide resistance management in red legged earth mites. In the past, her research has largely focused on using techniques of molecular biology and biochemistry to understand role of ceramide-metabolism enzymes in insect development and longevity. During her PhD in Zhejiang University, China, she reported the cloning, biochemical characterization, and functional analysis of Drosophila alkaline ceramidase (Dacer), suggesting that Dacer plays an important role in the Drosophila development and longevity by controlling the metabolism of ceramides. She then worked as a research fellow in Jiangsu academy of agricultural sciences, China, characterizing ceramidase and sphingomyelinase in Chilo suppressalis. She was also involved in transcriptome analysis of Scirpophaga incertulas with focus on bet-hedging genes. From 2014, Yang shifted focus into population genetics where she explored fine-scale processes of gene flow and dispersal in resistant red legged earth mites. This knowledge can be applied to better understand the routes resistant individuals have dispersed along, that may be important in reducing the risk of resistance spreading further.

Xuefen completed her Master’s degree (Biochemistry and Molecular Biology) at Sun Yat-Sen University, China, in 2017. Her previous research focused on functional genomics, more specifically, she studied the immunity of amphioxus, aiming to understand the origin and evolution of the vertebrate immune system. Her doctoral project will mainly focus on Bryobia mites and Vegetable leafminers, which are serious crop pests in Australia. She is supervised by Ary, Paul and Peter.
Her project includes two parts: First to investigate the species complexity of Bryobia mites in broad acre crops and pastures across Australia. Since the identification of Bryobia mites are often difficult given their small size and lack of suitable morphological characters, there is little information known about their basic biology and ecology worldwide. In this part, DNA barcoding will be used in Bryobia mites to delineate and identify morphologically cryptic species which is important for implementing effective pest control strategies. The second part of the project will focus on the vegetable leaf miner (VLM), which is a polyphagous species of agromyzid fly capable of infesting vegetable and flower crops and driving severe crop losses. Since it was found in Australia in 2015, on the Cape York Peninsula, it is now at a high risk of expanding its range and causing severe detrimental impacts on Australian agriculture. For that reason, it is important to figure out the invasion route of the VLM and study its potential establishment routes, which she will use molecular, morphological and modelling data.
Marianne finished a Bachelor of General Biology at McGill University, Canada, in 2016. After coming over to Australia she completed a year of Honours under Professor Mark Elgar with the department of Zoology at Melbourne University, looking at the Australian meat ant Iridomyrmex purpureus behaviour and communication. She is currently enrolled in a Master of Philosophy with PEARG, as a part of the greater program for control, eradication and preparedness for the Vegetable Leafminer funded by Hort Innovation. The other project partners are the University of Melbourne, cesar, Plant Health Australia, AUSVEG and NAQS. She is supervised by Prof Ary Hoffmann, Dr Paul Umina and Dr Peter Ridland.
Her project will investigate the existing food web complex between host plants, leafminer fly larvae and their parasitoid wasps in Australia. This knowledge will help pinpoint local wasp species that could be applied as biological control agents in Integrated Pest Management (IPM) programs to help reduce pesticide usage. This will be valuable information to control the spread of several invasive leafminers species that are serious agricultural threats in other regions of the world and that are expected to soon reach Australian soil and crops. One of these leafminer species, Liriomyza sativae, has already been found in Queensland, at the tip of the Cape York peninsula.
Xuan Cheng, PhD candidate
Xuan completed his masters degree in Taiwan, studying the association between acetylcholinesterase and carbofuran resistance in Chilo suppressalis (striped rice stem borer). He is currently studying for his doctorate with a focus on the pest management for Halotydeus destructor (redlegged earth mite, RLEM), an invasive species introduced from South Africa into Australia. RLEM is a winter-active
mite pest, attacking a broad range of agriculturally significant plant species in Australia. Non-diapause eggs are deposited by the female in winter while diapause eggs were produced and contained in the female body. Diapause eggs can survive applications of pesticides as well as summer heat and desiccation. Currently registered pesticides can only kill mites of active stages (e.g., larvae, nymphs and adults) and hence applications of pesticides have to be carefully timed before the production of diapause eggs. Furthermore, pesticides resistance to pyrethroid and organophosphate chemicals in active mites have been found in some populations. In order to manage pesticide resistance, Xuan’s project includes three research areas:
- Understand the dominance pattern and fitness cost of L1024F substitution in the para gene in association with pyrethroid resistance.
- Investigate the mechanism of diapause induction and diapause intensity in order to improve the applications of pesticides.
- Survey the host adaptation of RLEM and the fitness cost during crop rotation, a non-chemical control option.

Yifan Zhang, Masters student
Yifan graduated from the Ocean University of China in 2015 and obtained a Bachelor of Biological Science (Marine Biology). After that, Yifan become a Master student of Biotechnology at the University of Melbourne. In 2017, she changed major and joined in PEARG group, focusing on the project: Costs of Wolbachia infection in mosquitoes under different rearing conditions and between nuclear-mitochondria genomes.
Yifan has two main research interests: The first is the interaction between two primary environmental factors, nutrition and temperature and how these impact on mosquitoes with Wolbachia infections. The second aspect of the project focuses on the nuclear and mitochondria incompatibility impacts the Wolbachia-infected Aedes aegypti.
Effect of environment on stability of Wolbachia in Aedes aegypti mosquitos.
Moshe obtained a Bachelor of Science from the University of Melbourne in 2016. He joined PEARG the same year to commence his Masters, focusing on the population genomics and dispersal of mosquito vectors of dengue and other arboviruses in Southeast Asia.
Moshe’s masters research has two key aspects: The first focuses on understanding the extent and impact of population structure and genetic differentiation on Aedes albopictus mosquitoes across Peninsula Malaysia. The second seeks to use estimates of genetic relatedness to tease out patterns of Aedes aegypti dispersal across an urban landscape in the city of Petaling Jaya, Selangor. Both are closely connected to Wolbachia release programs, and intended to assist in optimizing these releases over different regions and local environments.

Samantha graduated with a first degree, Bachelor of Science Zoology, she remained at Aberystwyth University, Wales to undertake a Masters Degree in Managing the Environment, finishing in 2012. Her undergraduate thesis investigated the effects of urbanization on garden snails (Cornu aspersum Müller) and the results were later presented on BBC’s ‘Autumnwatch’. Research for her Master of Science thesis commenced in conjunction with Sustainable Forest Management Ltd and investigated the effects of plantation on ancient woodland sites (PAWS) on the abundance and diversity of arthropods.
She volunteered at the Natural History Museum in London, UK where she worked alongside Dr Andrew Polaszek, sorting through samples collected from different geographic regions and identifying parasitic Hymenoptera (particularly the superfamily Chalcidoidea). During this period, she published three papers.
Samantha’s PhD began in September 2016 at the University of Melbourne with Professor Ary Hoffmann, Dr Paul Umina and Dr Sarina Macfadyen at CSIRO acting as her supervisors. Her research fits within a larger, national Grains Research and Development Corporation (GRDC) project investigating beneficial species that can be used to control agricultural pests in grain crops.

Oliver completed his Bachelor of Science at Monash University in 2016 (Ecology and Conservation Biology/Zoology), and during the final years of his degree, he worked as a technical assistant in an insect physiology lab at Monash’s Clayton campus. He became interested in entomology as applied to agricultural pest management following a research placement with CSIRO in 2015/2016, investigating the life history of silverleaf whitefly (Bemisia tabaci).
With PEARG, Oliver’s study focuses on earwigs as pests of grain production in Australia, developing and refining identification techniques using DNA markers. Additionally, he aims to determine some of the conditions that might induce the European earwig (Forficula auricularia) to act as a pest, beginning with the effects of environmental stressors on its feeding behaviours.

Rujiporn is a population geneticist whose main interest is in the genetic management of rare species. She completed a Bachelor of Science with First Class Honours in 2009 at Murdoch University. Working with the Department of Biodiversity, Conservation and Attractions (Western Australia), her honours project was aimed to understand reproduction biology, mating system and pollen dispersal of Banksia nivea spp. uliginosa in the fragmented Busselton ironstone community. While she was undertaking her honours, she was also involved in a similar project for Calothamnus quadrifidus. She then worked as a Phytophthora research scientist in the same department, conducting a new phosphite application field experiment and detecting Phytophthora cinnamomic in suspected areas such as national parks.
Rujiporn developed an interest in conservation genetics and pursued a PhD at the University of Western Australia. Her PhD, which was completed in 2016, investigated genetic consequences of population mixing in translocations of burrowing bettongs and island dibblers as well as population structure and dispersal of mainland dibblers. The focuses of this project were on short- and long-term effects of admixture, factors influencing the genetic contributions of parental lineages and how population structure and dispersal patterns can be used in founder selection.

James Maino, Honorary Research Fellow
James researches better approaches to forecast and manage risk surrounding outbreaks of agricultural invertebrate pests. Part of this work aims to address the increasing problem of pesticide resistance in Australia, whereby a combination of resistance surveillance, novel genetic techniques, and predictive modelling are used to develop management strategies. He is interested in using the latest digital resources (e.g. satellite based climatic and land-usage data) and analysis methods that incorporate mechanistic processes to better predict pest dynamics so that impacts can be anticipated and minimised.
In 2016 James was jointly awarded a PhD at the University of Melbourne and Vrije Universiteit (Amsterdam) under the supervision of Michael Kearney and Bas Kooijman.
James is currently involved with research projects on some important species of aphids and mites, aiming to develop better management practices that utilise a variety of control strategies, in the face of increasing chemical resistance problems.James also is applying modern data sets and analysis techniques to better assess risks of biosecurity threats to agriculture, which not only includes novel species, but novel biotypes (i.e. new genes that occur overseas but not in domestic varieties).

I am a master student from Berlin/Germany and joined the Hoffmann lab for 6 months to complete an internship as part of my masters program at the Freie Universität Berlin. I obtained my bachelor degree in biology 2016 and worked with a variety of insects, including flies, wasps, termites and different species of beetles. During my final bachelor project, supervised by Prof. Jens Rolff, I investigated antimicrobial peptides in the immune system of T. molitor respectively the ability of bacteria to evolve resistances against these substances. Further I also studied immune responses of T. molitor during infections with the entomopathogenic fungus B. bassiana. During my stay with PEARG I gained skills in the maintenance of Mosquito colonies, artificial blood feeding methods as well as DNA analyses.
I am currently working on the impact of non-human blood types (e.g pig and sheep) on Ae. aegypti and its Wolbachia infection.

Li-Jun is a research fellow in the Institute of Plant and Environmental Protection, Beijing Academy of Agriculture and Forestry Sciences. He completed his Ph.D. studies at Beijing Forestry University in 2016. His studies focused on the origin and dispersal of several pest insects. This January he joined PEARG as a visiting scholar investigating interactions between Wolbachia and viruses. He will detect Wolbachia strains in field populations of Drosophila simulans and investigate the abundance of viruses in Wolbachia positive and negative populations from different locations.
I received my PhD many years ago at the University of Texas Southwestern Medical School with a Drosophila evolutionary geneticist, Costas Kastritsis who had studied inversion polymorphisms with T. Dobzhansky. I then did a post doc at the University of Texas, Austin, studying ecdysone and chromosome activity in Rhynchosciara, particularly in relation to gene amplification. My supervisor was the Brazilian geneticist, Crodowaldo Pavan. After that I came to Melbourne and worked for several years in the Melbourne University Genetics Department at the end of the time of Michael White’s tenure there. I made the mistake of trying to raise Rhynchosciara in Australia since I was very familiar with that fly and I felt that there was a lot of work still to be done. That attempt was not successful. Subsequently, I had a long period at the University of Sao Paulo, Brazil working with Professor Francisco Lara. I have been in and out of Brazil for many years through various political changes and still visit there. During some of that period I was a lecturer for about 8 years at the College of Advanced Education which became the Department of Education of the University of Melbourne. I began to work with Ary when I came back from a long period in Brazil and he was still at La Trobe University. I could have retired but I decided to work a little longer. My first project involved clines in inversion polymorphism. I have been associated with Ary’s group ever since, working casually on various projects and most recently in an honorary position. My speciality is chromosomes, particularly fly chromosomes, which most people do not work with anymore.
Chromosome evolution in Australian Scaptodrosophila: I have examined mitotic chromosomes of a number of Australian Scaptodrosophila species and carried out C-banding and Ag-NOR banding. I have also examined polytene chromosomes. Since Ag-NOR banding was only variably successful, I may also do rDNA in situ hybridization when I am in Brazil. I intend to put together my results in a manuscript showing the relationship among the species.
