Dr. Patricia Dahia is a tenured associate professor in the Department of Medicine at the University of Texas Health Science Center at San Antonio (UTHSCSA), and a member of the Cancer Therapy and Research Center (CTRC), the NCI-designated Cancer Center at UTHSCSA. Her research program is centered on the study of hereditary malignancies as model systems to characterize genetic heterogeneity in cancer and to uncover intersections between oncogenic and metabolic pathways. 

Dr. Dahia’s goal is to understand how dysfunction of these genes contributes to oncogenesis, and to use this knowledge towards improved diagnosis, risk assessment, prognostic modeling, and the development of personalized therapeutic strategies.
