Paola Betancur, Ph.D.
Department of Radiation Oncology
My passions are family, science, and long-distance running.
Meet Dr. Betancur
Dr. Betancur received her B.S. degree in Biology from Stony Brook University and her Ph.D. degree in Molecular Cell Biology from Caltech. Then, as a postdoctoral fellow at Stanford University she studied the transcriptional regulation of CD47 (an immune escape cell-surface protein present in all cells) that provides a “don’t eat me” signal to macrophages, and other immune cells, thus protecting cells from being targeted and cleared by the immune system.
