César López Angel, MD, PhD is a fourth-year R38 research-track pediatrics resident at Duke. He was born in Guadalajara, México but grew up in San José, CA since the age of four. He attended college at Harvard where he studied candidate HIV vaccines in pre-clinical studies and in clinical trials. He then completed his MD and PhD in immunology at Stanford where he characterized the effects of chronic infection and aging on immune homeostasis, vaccination, and immune signaling networks. His current work in the Duke Center for Human Systems Immunology, and in collaboration with the HIV Vaccine Trials Network, focuses on determining whether baseline or post-HIV vaccine immune signatures affect the risk of acquiring HIV, and whether preexisting CMV immunity modifies the relative risk of HIV acquisition. As Medical Education Chair for Duke MHA, César aims to enhance the sense of community among URiM students, housestaff, and faculty, and to strengthen mentorship relationships across the medical trainee spectrum.
