Robert L. Judson-Torres, PhD, BA
- Departments: Dermatology - Assistant Professor, Oncological Sciences - Adjunct Assistant Professor
Academic Bio: Dr. Robert Judson-Torres received his Ph.D. from the University of California, San Francisco in Biomedical Sciences in 2012 for his discovery and mechanistic dissection of microRNAs that mediate somatic cell reprogramming. He was subsequently awarded the NIH Director’s Early Independence Award. He initiated an independent research program as a Sandler Fellow in the UCSF Program for Breakthrough Biomedical Research.
From 2014-2019, Dr. Judson-Torres headed his research group at the UCSF Helen Diller Family Comprehensive Cancer Center. He pioneered the use of CRISPR/Cas9 engineering in primary human melanocytes as a model system for melanoma initiation and focused on identifying the transcriptional programs that precede tumorigenesis. In 2019, he joined the faculty of the Department of Dermatology and the Huntsman Cancer Institute of the University of Utah.
Research: Dr. Judson-Torres’ research program seeks to understand the dynamic transcriptional programs regulating human melanocytes and how disruptions to these programs permit or drive the early stages of melanoma development. Melanoma is a skin cancer that is curable if detected early, but frequently fatal if left unchecked. Melanomas are derived from melanocytes that have acquired specific genetic mutations. However, the majority of melanocytes that acquire these exact mutations do not progress to melanoma. Both the intrinsic transcriptional and epigenetic programs as well as the external environmental and chemical factors that govern the probability of transformation are poorly understood. His laboratory studies diverse populations of primary human melanocytes and melanoma cell lines using single cell sequencing, live quantitative phase imaging, and CRISPR/Cas9-based precision engineering. Translational aspects of his work include the identification of transcriptional programs as potential biomarkers for early melanoma diagnosis and the discovery of administered compounds that alter the probability of transformation.
Teaching: Dr. Judson-Torres serves as a mentor for students at many levels of education, from high school through post-doctoral and clinical fellows and residents. In addition to training students in molecular, cell and translational research, he is also particularly interested in career development for graduate students and post-doctoral fellows. Dr. Judson-Torres is an avid believer that well-trained scientists should be professionally serving our communities in all aspects of organization, government, planning and education, in addition to academic and industrial research.
Service: Dr. Judson-Torres has served as a member and instructor for the UCSF Career Development and Enrichment Programs, a board member for the UCSF Graduate Division Alumni Association, and a member of the University of Utah Academic Senate Special Committee focused on updating the policies, rights and benefits of post-doctoral scholars. He helps to spearhead the Huntsman Cancer Institute Postdoc Showcase. He has organized multiple international symposia focused on expanding and standardizing practices in digital holographic cytometry. He serves on the council of the Pan-American Society for Pigment Cell Research.
