I am an Assistant Professor in the Computer Science department, with affiliate appointments in the Electrical & Computer Engineering department, the National Center for Supercomputing Applications (NCSA) and the Infection Genomics for One Health theme of the Institute of Genomic Biology (IGB) 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. In addition, I develop algorithms to reconstruct patterns of spread in disease outbreaks.
