Welcome to my webpages !
I am a Lecturer in the School of Mathematics and Statistics at the University of Melbourne.
My research interests are in partial differential equations, geometry and analysis.
In 2012, I obtained my Ph.D. from the University of Cambridge as a student of Mihalis Dafermos. Prior to joining the University of Melbourne in 2018, I held postdoctoral fellowships at the University of Toronto, MSRI, Berkeley, and most recently Sorbonne Université, Paris. Please refer to my curriculum vitae for a detailed academic history.

Calculus 2: Advanced (MAST10021)
This course is offered annually for first year students in Semester 2.
I have been teaching it every year since 2020 when it was first introduced.
FAQ about this course:
- What is the difference between Calculus 2: Advanced and Calculus 2?
I would say, while the topics covered in this course are broadly the same as in MAST10006 Calculus 2, the material is more “advanced” in the sense that you will see more proofs and concepts, and fewer examples with “ad hoc” solutions. Here we aim to strike a balance between the theoretical underpinnings of Calculus and its practical applications, which also prepares you to take other classes is mathematics & physics.
- What is the difference between Calculus 2: Advanced and Accelerated Mathematics 2?
In comparison to Calculus 2 the course Accelerated Mathematics 2 proceeds quicker, but not at a deeper level. The idea of the new courses in the Advanced stream is to offer solid entry courses in mathematics, where the foundations of these subjects are developed with more care, and more emphasis on the underlying proofs is given, both in the presentation of the material, and the skills acquired by the student.
- How do I enroll?
Please contact firstname.lastname@example.org for all questions related to enrollment.
- Is there a book you recommend?
I like Spivak‘s “Calculus” which gives a beautiful introduction to Calculus at the intended level for this course. In fact, large parts of this course are based on Spivak‘s text. I also recommend Folland‘s “Advanced Calculus”.
