Peter Ly received his B.A. in Biology from Baylor University and earned his Ph.D. in Cancer Biology from UT Southwestern Medical Center. During graduate training with Jerry Shay and Woodring Wright, he studied how aneuploidy, an abnormal number of chromosomes, can promote malignant transformation. He pursued postdoctoral training at the University of California San Diego and Ludwig Institute for Cancer Research with Don Cleveland. His postdoctoral research focused on reconstructing the mechanisms of complex structural genomic rearrangements using chromosome-specific mis-segregation approaches in human somatic cells. In 2019, Dr. Ly joined the faculty of UT Southwestern Medical Center as an Assistant Professor in the Department of Pathology and CPRIT Scholar in Cancer Research. He holds a secondary appointment in the Department of Cell Biology and is a member of the Harold C. Simmons Comprehensive Cancer Center as part of the Cellular Networks in Cancer Program. He has been an active member of the American Society for Cell Biology since 2013.
