Joshua Breunig, PhD, is an Assistant Professor at Cedars-Sinai Medical Center with a joint appointment in the Department of Medicine at the David Geffen School of Medicine at UCLA. Dr. Breunig received his Ph.D. from Yale University. Currently, he investigates the transcriptional regulation of neural precursor cells (NPCs) in the brain, specifically exploring the pathways governing the transformation of NPCs into brain tumor progenitors. Using a next-generation brain tumor model, his lab introduces patient-specific mutations to create “personalized” tumors in immunocompetent animal models. Dr. Breunig is supported by funding from the American Cancer Society, and NIH/NCI.
