Peter Douglas, Ph.D., is an assistant professor in the Department of Molecular Biology at UT Southwestern Medical Ceneter. He receiving his bachelor’s degree in Biochemistry from the University of Colorado in Boulder and earned his Ph.D. from the University of North Carolina in Chapel Hill in the Department of Cell and Developmental Biology. As a graduate student in laboratory of Dr. Douglas Cyr, Peter used different methods in biochemistry, genetics, and cell biology to understand the mechanisms by which protein homeostasis machinery detoxifies misfolded, aggregation-prone proteins. In 2009, he joined the laboratory of Andrew Dillin at the Salk Institute in La Jolla, California, and later the University of California in Berkeley, California. There he uncovered novel links between classical stress response function and the actin cytoskeleton network. In 2015, Peter joined the faculty at UT Southwestern as an assistant professor in the Department of Molecular Biology. Peter was awarded fellowships from the American Heart Association, National Institute of Health on the Neuroplasticity of Aging and the George E. Hewitt Medical Foundation. He also received a Pathway to Independence Award (K99/R00) from the National Institute of Health. As a assistant professor, Peter received a Cancer Prevention Research Institute of Texas (CPRIT) recruitment of first-time, tenure-track faculty member award and is an Endowed Scholar in biomedical research.
