Viruses have evolved to modulate host cell metabolism to ensure optimal replication and spread (1). My graduate work revealed that glycolysis, fatty acid synthesis, and amino acid metabolism are critical during infection with Kaposi’s Sarcoma Herpesvirus (KSHV), a cancer-causing virus (2–4). Herpesviruses establish lifelong infections in their hosts and express numerous homologues of host genes (5). For example, KSHV has hijacked a copy of a G protein-coupled Receptors (GPCR) from the host genome, which it expresses during infection (6). Interestingly, my postdoctoral research has focused on understanding how cellular-GPCR signaling controls cellular metabolism (7). My data show that GPCR signaling from both the plasma membrane as well as the endosomal membrane contribute to transcriptional control of metabolic genes. We hypothesize that the viral GPCR (vGPCR), expressed by KSHV, regulates host cell metabolism. Determining the molecular mechanisms activated by vGPCR can uncover potential therapeutic targets to treat KSHV infection.

My interdisciplinary research program focuses on the molecular biology of host-pathogen interactions. I am excited to collaborate with SFSU faculty, the GTAC facility, and the CMIC to accomplish our lab's research goals. My proposed research will establish a new model for investigating viral influence on host cell metabolism, combining techniques and tools from both my graduate and postdoctoral work. This research is designed to inspire undergraduate and masters student researchers interested in exploring human disease at the molecular level.

My lab aims to provide a space for eager students, at all levels, to develop and practice their research skills. Contact me if you are interested in learning more!
