Research Summary

I am an Assistant Professor of Medicine at the University of California San Francisco, appointed to the Division of Pulmonary and Critical Care Medicine at the San Francisco General Hospital. As a clinician boarded in internal medicine, intensive care medicine, and respiratory medicine, I have expertise in diagnosing and managing the spectrum of lung disease spanning lung cancer, asthma, chronic bronchitis, and e-cigarette or vaping product use-associated lung injury (EVALI). As an NIH-funded patient-oriented researcher, I have expertise in respiratory physiology, vulnerable populations, and causal inference methods in observational research. I am an experienced collaborator and I have worked on several national and international multi-site observational cohort studies. My current research projects investigate the effects of environmental exposures, such as marijuana and vaping aerosol, and chronic viral infections, such as HIV and hepatitis C virus infections, on lung health outcomes, including lung cancer.
