Peter Ly received his Ph.D. in Cancer Biology from UT Southwestern Medical Center and completed postdoctoral training in the Department of Cellular and Molecular Medicine at the University of California San Diego and the Ludwig Institute for Cancer Research. He is currently an Assistant Professor in the Department of Pathology at UT Southwestern Medical Center.
Dr. Ly's research group is broadly interested in the cellular mechanisms of genomic instability and their biological consequences in human health and disease, particularly in the context of cancer development. Major areas of investigation include how defects in mitotic cell division, chromosome segregation, centromere regulation, and DNA repair pathways shape the chaotic mutational landscape of cancer genomes. The laboratory is currently focused on exploring how mitotic errors trigger structural genomic rearrangements, which can span  a spectrum of complexity that ranges from simple  chromosomal translocations to catastrophic forms of chromothripsis.
