Research Interests

I am a virologist studying host-pathogen interactions in the heart and pancreas. My primary goal is to identify potential therapeutic targets that can translate to the development of antivirals that could combat both acute and chronic viral diseases. Though I study a variety of human viruses, my current work focuses on coxsackievirus B3 (CVB3), a common juvenile pathogen, which is known to cause systemic inflammatory diseases such as myocarditis and pancreatitis. We have reported that CVB3 exploits host mitochondria in a variety of ways to support viral replication, disrupt antiviral immunity and promote viral egress. Our findings have helped us identify a number of potential therapies including menthol. This common, affordable cooling compound limits proviral mitochondrial fission processes and has shown immense promise in suppressing CVB3 infection as well as limiting CVB3 pancreatitis and myocarditis. I have taught several undergraduate and graduate courses as well as trained a number of undergraduates, graduates and postdocs. Though I have worked at a medical center for a number of years, my goal was always to pursue a tenure-track faculty position which would allow me to further develop my research program as well as teach students both in the classroom and the lab.
