Peter Ly received his B.A. in Biology from Baylor University and 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 – promotes malignant transformation. He conducted postdoctoral training at the University of California San Diego and Ludwig Institute for Cancer Research with Don Cleveland, where he developed chromosome-specific mis-segregation approaches to reconstruct the mechanisms leading to complex genomic rearrangements. 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 a member of the American Society for Cell Biology since 2013.
