An Iowa native with an unfavorable HLA repertoire who was inoculated with the research virion while working towards a BS in biochemistry at the University of Iowa, I managed to weather the acute stage of infection exploring mechanisms of enzyme catalysis in the laboratory of Dr. Amnon Kohen. Dormancy did not last through dental school and the HHMI-NIH Research Scholars Program took me to Bethesda where I joined the laboratory of Dr. John O’Shea and surfed the IL-17 wave exploring the role of STAT signaling within T helper cell differentiation and disease. My Midwest nomad years continued through the NIH Oxford-Cambridge program and a collaboration with Professor Fiona Powrie, FRS, investigating various aspects of mucosal immunity utilizing a mouse model I had generated with help from Dr. Rafael Casellas. Following defense of my thesis, I returned to Iowa and reintegrated into the dental curriculum. My DDS was immediately chased with entry into the Oral & Maxillofacial Pathology residency training program. T cell exhaustion has since settled in and I come to the Karandikar lab in hopes of gaining a deeper understanding of CD8 T cell biology, their roles in autoimmune disease and potential utility in adoptive immunotherapy.
