Pediatric Malignancies

Research Summary

I am a developmental biologist as well as a pediatrician and clinical geneticist, and I am interested in translating an understanding of developmental mechanisms into advances for regenerative medicine. After completing the MD/PhD degrees and a pediatric residency, I trained in Medical Genetics. As a physician scientist, I treat patients with various syndromes, including those that predispose patients to cancer. As the Chief of the Division of Genetics at UCSF and Chair of the Division of Craniofacial Anomalies at UCSF, I take a strong interest in integrating clinical and research activities. Work in my research group centers on organ development and regeneration, with a major focus on understanding the processes underlying stem cell-based renewal and on integrating evolutionary and developmental approaches.
