Curriculum Vitae

I am an Assistant Professor in the Department of Microbiology and Molecular Biology at Brigham Young University. My research is centered on improving the immune system response to infectious disease and I teach Advanced Molecular Biology.

Previously I was an Instructor and Postdoctoral Fellow at the Washington University School of Medicine in St. Louis. I earned my Ph.D. from the University of Illinois and my undergraduate and masters degrees are from Brigham Young University.
 Teaching Interests
Immunology, Host-pathogen interactions, and Molecular Biology
 Research Interests
My research group is working to understand the mechanisms of T cell activation and memory cell formation in response to pathogens. Memory cell formation is a hallmark of the adaptive immune system and memory T cells rapidly respond to a secondary challenge and are critical for numerous vaccine strategies. In recent years our understanding of cytotoxic memory T cells has increased substantially, but our understanding of memory helper T cells remains incomplete. We have generated two helper T cell receptor transgenic mice specific for the same naturally occurring epitope from Listeria monocytogenes. T cells from these mice have dramatically different primary and secondary responses to infection. This project will help us better understand ways to effectively improve vaccines and immunity to infection.

A second focus of my lab is to understand how high affinity T cell receptors differ in their ability to recognize antigen and cause T cell activation. High affinity T cell receptors are engineered using yeast display and directed evolution and represent a novel tool for targeting T cell epitopes that are not recognized by antibodies. High affinity T cells may be useful as therapeutics in an infectious disease setting when coupled with pro-inflammatory cytokines or in an autoimmune setting when coupled with anti-inflammatory cytokines.
