Michel Giovanni Santiago-Martinez (Geo) has joined the Department of Molecular and Cell Biology as an assistant professor. Santiago-Martinez is a microbiologist from Universidad Nacional Autónoma de México (UNAM) and The Pennsylvania State University. He is interested in the ecophysiology of archaea and anaerobic bacteria, and how energy status influences their ability to resist environmental stress conditions, such as exposure to oxygen and nutritional starvation. His research goal is to understand the function of anaerobic microorganisms in biogeochemical cycles and host-associated microbiomes. He is also interested in bringing up-to-date knowledge of archaea to the classrooms and outreach activities, as well as promoting more inclusive science through mentoring activities and service initiatives.
