I originally trained as a mathematician (MSci Mathematics, Imperial College, 2002) before spending time in a cancer genetics lab as part of my interdisciplinary PhD (PhD Mathematical Biology, UCL, 2009). As a postdoc, I worked in Nick Wright's lab at the Cancer Research UK London Research Institute studying clonal expansions in human tissues (2008-2011), and Carlo Maley’s lab at UCSF looking at the pattern of clonal evolution in human cancers (2011-2013).
