Megan J Smithey

Research Assistant Professor

Megan Smithey received her doctoral degree from Oregon Health & Science University in 2005, and joined the Nikolich-Zugich research group in 2008. Her research is primarily focused on understanding how persistent viral infections impact the aging immune system in both model organisms and human translational research. After growing up in the soggy Pacific Northwest, she finds the Tucson climate to be a revelation, and tries to get outside as much as possible.
