Senior Researcher, Nuffield Department of Medicine
I am a researcher in pathogen phylodynamics, with a particular interest in inference of who infected who. I am also interested in investigating the effects of sampling bias in molecular epidemiological studies. I obtained my PhD in 2015 at the University of Edinburgh under Professor Mark Woolhouse and Professor Andrew Rambaut. I currently work at the BDI with Professor Christophe Fraser on the PANGEA HIV project, focussing on the reconstruction of transmission patterns within a very large and rich dataset of next-generation HIV sequences.
Software in which I have a hand:
Phyloscanner (construction of phylogenies and investigation of transmission in large genetic datasets)
STraTUS (an R package for enumeration and uniform sampling of transmission trees for a fixed phylogeny)
Inferring HIV-1 transmission networks and sources of epidemic spread in Africa with deep-sequence phylogenetic analysis.
