Research Interests:

Molecular, Cellular and Virologic Characterizations of HIV-1 Viral Protein R (Vpr) Interactions with Host Cellular Responses Research Interests

My general research interest is in the area of host-pathogen interactions specifically to study the effects of viral infections on host cellular activities. Our current research focus is to investigate the roles of HIV-1 viral protein R (Vpr) in cell cycle G2/M controls, apoptosis and elicitation of other host cellular responses. Our research strategy is to integrate the use of fission yeast (Schizosaccharomyces pombe) as a model system with further translations of yeast findings into mammalian and viral infection systems. This combined research strategy represents main research strength of our research programs, which allows us to uncover many of the molecular or cellular insights of HIV-1 Vpr that are sometimes difficult or impossible to reveal solely by studying mammalian cells.
