David Helekal
I am a PhD student interested in statistical and probabilistic models for infectious disease epidemiology.
Research Interests
My main interest lies in how bayesian modelling of non-homogenous populations can be achieved using phylodynamics and coalescent processes. Such models are of interest in infectious disease epidemiology as they can be used to characterise and study outbreaks, emergence of new variants, case imports, or to estimate epidemiological quantities of interest.
