My group’s focus has been on the study of mammalian viruses that are significant causes of morbidity and mortality in humans, in particular hepatitis B virus (HBV), hepatitis C virus (HCV), and dengue virus. We are especially interested in using chemical tools to elucidate molecular mechanisms underlying the replication of viral pathogens and to validate new antiviral targets and strategies. Current themes in my laboratory include the use of small molecules and RNAi as complementary tools to interrogate the role of specific host factors in viral replication; the use of mass spectrometry-based methods to investigate the structure and function of specific lipids in viral replication; the use of activity-based chemoproteomic profiling to characterize virus-induced changes in the host NTPome; exploitation of the host reactive “cysteineome” to develop irreversible, host-targeted antiviral compounds; and the investigation of polypharmacology as a strategy to develop more effective antivirals with higher barriers to resistance.
