Steven Yukl, MD

Associate Professor

Infectious Diseases

I am a physician-scientist at UCSF and the San Francisco VA. Since 2005, I have been conducting laboratory-based research aimed at understanding the barriers to curing HIV. My laboratory focuses on investigating the mechanisms that allow HIV to establish a latent infection (which is widely regarded as the main barrier to curing HIV) in the blood and tissues. After the start of the COVID-19 pandemic, we also became interested in the transcriptional regulation of SARS-CoV-2, another RNA virus. We are currently investigating how SARS-CoV-2 subgenomic transcription (which is analogous to RNA splicing) allows for variation in the expression of different coronavirus genes over time, and how these SARS-CoV-2 subgenomic RNAs interact with human cells to govern the pathogenesis of COVID-19.
