Overview

Peter J. Mullen, Ph.D., is an Assistant Professor of Microbiology and Immunology in the Keck School of Medicine at the University of Southern California (USC). He has a secondary appointment in the Leonard Davis School of Gerontology at USC.
He has spent over 10 years studying the regulation and role of metabolism in tumor growth and viral infections. The overall goal of his recently established lab is to understand how whole-body metabolism alters respiratory virus replication, cancer progression and aging. By elucidating specific requirements for different nutrients, he aims to identify and develop novel strategies that reduce disease and increase lifespan.
