Dr. Ryan Potts grew up in North Carolina and obtained his B.S. from the University of North Carolina at Chapel Hill in 2000. Subsequently he worked as a Research Assistant at UNC studying the intracellular signaling processes that regulate neuronal cell death. In 2003 he entered into the Cell Regulation Ph.D. program at UT Southwestern Medical Center under the mentorship of Dr. Hongtao Yu in the department of Pharmacology. He completed his dissertation in 2007 studying the molecular and biochemical processes that safeguard the genome from DNA damage-induced mutations. In 2008 he was awarded the Sara and Frank McKnight independent postdoctoral fellowship in the department of Biochemistry at UT Southwestern Medical Center. During this time his research focused on understanding the basic molecular, genetic, and cellular events that give rise to cancer. His lab biochemically defined a novel family of cancer cell-specific proteins, called MAGE proteins, that promote tumor growth. In 2011 he was appointed Assistant Professor and Endowed Scholar in Biomedical Research in the department of Physiology at UT Southwestern Medical Center. He was also awarded a Cancer Prevention and Research Institute of Texas (CPRIT) Scholar in Cancer Research Award. His lab is now focused on elucidating the biochemical, cellular, and physiological function of MAGE proteins in tumorigenesis and in normal somatic and germ cells.
