Sean Morrison, Ph.D. is the Mary McDermott Cook Chair in Pediatric Genetics and the Kathryne and Gene Bishop Distinguished Chair in Pediatric Research at the University of Texas Southwestern Medical Center.

The Morrison laboratory studies the cellular and molecular mechanisms that regulate stem cell function and the role these mechanisms play in cancer. They identified a series of mechanisms that distinguish the self-renewal of stem cells from the proliferation of restricted progenitors in the same tissues and identified niches that maintain stem cells in adult hematopoietic tissues.

The Morrison lab has also studied the mechanisms that regulate metastasis, discovering that melanoma metastasis is limited by oxidative stress. Rare metastasizing cells survive this stress by undergoing metabolic changes that reduce the generation of reactive oxygen species and confer oxidative stress resistance. This suggests the possibility of limiting cancer progression with pro-oxidant therapies that exacerbate the oxidative stress experienced by cancer cells.

Dr. Morrison completed a B.Sc. in Biology and Chemistry at Dalhousie University (1991), a Ph.D. in Immunology at Stanford University (1996), and a postdoctoral fellowship in Neurobiology at Caltech (1999).
