Research Interests: Viral pathogenesis, HIV

My laboratory investigates the pathogenesis, treatment and prevention of lentiviral immunodeficiency infections caused by HIV-1 and its simian relative, SIV, using such technologies as in situ hybridization, in situ tetramer staining and quantitative image analysis to visualize infection and the hosts? cellular immune response in tissues. Much of our recent work has focused on sexual mucosal transmission and the acute stage of SIV infection, the roles of ?resting? and activated CD4 T cells in establishing infection, and the mechanisms of the massive depletion of CD4 T cells in the gut. Going forward, these studies provide a foundation for studies of the correlates of protection for attenuated vaccines, and the development of vaccines and microbicides to prevent transmission. My laboratory has also undertaken a comprehensive microarray analysis of HIV-1 and SIV infections with the objectives of understanding pathogenesis and identifying novel targets for treatment and prevention. Current efforts focus on broadening the microarray analysis to encompass the early through late stages of HIV-1 infection, and mapping genes identified in the analysis to gain insight into their function in HIV-1 infected lymphatic tissues, the principal sites of virus production, persistence and pathology.

Featured News & Events

'Wisc-e-sota', a Joint UMN-UW Virology Training Grant Symposium was first held on Friday, Sepbember 20th, 2013 at the Uniiversity of Wisconsin-La Crosse, Cartwright Center. This was the inaugural collaborative symposium of the NIH T32-supported virology training programs at the University of Wisconsin-Madison and the University of Minnesota-Twin Cities. Talks and poster sessions were presented by students, postdocs and faculty. The second UMN-UW Virology Training Grant Symposium will be held in the Fall 2014. Details to follow.

The 2014 IMV Symposium will be held on May 12, 2014 and Mark Denison (Vanderbilt) and Bert Semler (UC-Irvine) will be the Keynote Speakers. Click on the link below to register and submit abstracts.
