The overall goal of my research is to explore mechanisms by which cellular stress responses regulate innate immunity to bacterial infection.
I am interested in teaching topics that cover bacterial pathogenesis, immunology, molecular biology, and cell biology. I am also interested in mentoring students with different levels of education including undergraduate, veterinary, and graduate students.
