• mathematical modelling of
  1. ancestry and relatedness,
  2. demographic history of populations,
  3. evolutionary processes such as mechanisms of selection;
• statistical methods for the evaluation of forensic DNA profile evidence;
• measuring relatedness and its role in genomics analyses, including association studies;
• heritability and the genomic architecture of complex traits;
• predicting phenotypes from genotype and other data;
• analysis of other omics data (transcriptome, methylome, etc) together with genomics data.

I have worked with collaborators in many different fields, on genetic aspects of forensic science, crop research, ancient DNA, drug development and disease.  I have consulted with government and industry in many areas, most often relating to DNA profile evidence.  I also played a key role in synthesising and evaluating the evidence for certain bones found under a car park to be those of English king Richard III.
