I am a postdoctoral researcher in the Department of Infectious Disease Epidemiology, working with Prof Azra Ghani and Dr Patrick Walker on modelling the transmission of COVID-19. I also hold a position at Brown University in the Bailey Lab working on malaria population genetics.  


My undergraduate degree was in Natural Sciences at Pembroke College, Cambridge before completing a master's degree in Systems Biology, working on multi-omic computational methods for identifying new biochemical reactions indicative of disease.

For my PhD I worked on integrating genetic information into malaria transmission modelling with Prof Azra Ghani, Dr Lucy Okell and Dr Robert Verity. This work was focussed on extending malaria transmission models that have been used in creating global technical strategies for malaria control by including parasite genetic information.
