Research Interests

My research is focused on three main topics relating to sexually transmitted Human papillomaviruses (HPVs). The first area of emphasis is in the analysis of cis and trans-acting signals required for stable replication of HPVs.  A second area under study is the specific packaging requirements of HPVs.  In both of these studies, we make of use of a novel and convenient yeast system we have developed to model HPV functions and to identify cellular factors involved.  A final area of emerging interest for the lab is the analysis of HPV disease epidemiology in HIV positive patients in Zambia, Africa.
