I am a PhD student with Professor Nicholas Grassly in the Vaccine Epidemiology Research Group. My current work focuses on the transmission dynamics of wild poliovirus in Pakistan and Afghanistan. This involves the use of bayesian phylogenetic and coalescent methods to infer transmission routes over time using genetic data. The aim of this work is to better incorporate spatially and temporally biased sampling data in estimates of polio transmission dynamics. 

I have previously worked on risk assessments for poliovirus transmission in collaboration with the Global Polio Eradication Initiative and the World Health Organization. This work involved mixed effects regression modelling and identifying key high risk areas to target with future vaccination campaigns. 

My background is in biology with a masters in Epidemiology and Biostatistics
