Research Description
Virology! Cancer biology! Immunology! Systems biology! Gammaherpesviruses are cancer-causing viruses that infect the majority of humans. We are working to determine functions of viral proteins in infection and disease, identify host factors that block viral infection and prevent virus-driven cancers, and understand immune responses to chronic viral infections. Our major goal is to define the complex relationship between gammaherpesviruses and their hosts. To do so, we use both tissue culture and mouse models of infection. We employ many different techniques, including flow cytometry, fluorescence microscopy, bacterial genetics, viral genetics, in vivo reporter systems, immunologic assays, basic biochemistry, proteomics, transcriptomics, and CRISPR/Cas9 screens and knockouts. PLUS, we get to do cool science and figure out how stuff works!

Current Projects
1. Defining how host tumor suppressor p53 restricts gammaherpesvirus infection and tumorigenesis and understanding how gammaherpesvirus co-infection with malaria parasites causes lymphoma. (Topics: Cancer biology and infectious disease research)
2. We “humanized” a mouse virus, and we are now using this virus to define how a cancer-causing human virus, Kaposi sarcoma-associated herpesvirus, evades the immune response. (Topics: Immunology, viral pathogenesis, and genetics)
3. Developing vaccines against gammaherpesviruses – we patented a technique for making “dead” viruses that maintain antigenic epitopes. (Topics: Immunology, genetics, and biochemistry)
4. Defining the basic biology of how gammaherpesviruses infect and replicate in target cells – we recently completed a CRISPR/Cas9 screen and found lots of cool stuff to pursue! (Topics: Cell biology, molecular virology, and biochemistry)
