Lucy Ham

I joined the Theoretical Systems Biology Group at the University of Melbourne as a postdoctoral researcher in November 2018. My research interests are in the development of mathematical and statistical approaches for the analysis of biological processes. A particular focus of my recent work has been on developing stochastic models for understanding gene regulation.

I completed a Bachelor of Science at La Trobe University, graduating with Honours (1st) in mathematics and statistics in 2013. Following this, I received a Ph.D. in pure mathematics in 2017, under the supervision of Professor Brian Davey and Associate Professor Tomasz Kowalski. My Ph.D. research was in the mathematics underlying the theory of computing, with a focus on universal algebraic approaches to classifying the computational complexity of constraint problems.
