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 usually 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 digital holographic 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.
Dr. Judson-Torres serves as a mentor for students at all levels of education, from high school through post-doctoral and clinical fellows. 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.
