Dr. Marnocha joined the biology faculty in 2016. She received her B.S. from the University of Wisconsin – Green Bay and her Ph.D. from the University of Arkansas. Before coming to Niagara University, she was a postdoctoral researcher at the University of Delaware. She teaches courses in microbiology and environmental studies, along with General Biology and Senior Seminar. Dr. Marnocha is an environmental microbiologist with research interests in microbial biogeochemical cycling, endoliths (microorganisms that live in rocks), microbe-mineral interactions, and astrobiology. Her current work includes field research of acidic springs found at the Iroquois National Wildlife Refuge, where she investigates the microbial communities involved in sulfur cycling.
