I am an Assistant Professor in the Computer Science department and a Faculty Affiliate of the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC).

My research focuses on tumor phylogenetics in the context of intra-tumor heterogeneity. I develop phylogeny inference algorithms to study the progression of a tumor from its initial stage, where a healthy cell acquires its first somatic mutation, to the final stages, where tumor cells metastasize and invade and colonize distant organs and tissues.
