Dr Helen Alexander

Research Interests

I am a theoretical biologist, adding an experimental dimension to my work during my current postdoc. In my past and ongoing research I have developed mathematical (especially stochastic) models of population dynamic and evolutionary processes, mainly of microbial populations and infectious disease spread.

Key topics: bacterial and viral population dynamics, evolutionary rescue, drug resistance, mutation rates, phylodynamics, evolutionary epidemiology, stochastic models, maximum likelihood inference
