Mackenzie Gerringer (she/her/hers) is an Assistant Professor at the State University of New York at Geneseo. Her research centers on the physiology and ecology of deep-sea animals, including the planet’s deepest-living fishes.

She earned her PhD in Marine Biology from the University of Hawaii in 2017 before working as a postdoctoral researcher at Friday Harbor Labs, University of Washington. As a National Science Foundation Graduate Research Fellow, she studied drivers of depth zonation in the hadal zone, depths ranging 6,000–11,000 meters, and the notable success of hadal snailfishes (family Liparidae).

Her research explores how fishes are adapted to life in the amazing pressures, cold temperatures, and eternal darkness of the deep-sea using comparative techniques in taxonomy, functional morphology, cellular physiology, energetics, age and growth studies, and diet analysis.

She has spent over 200 days at sea exploring the ocean’s depths with free-vehicle landers, ROVs, and submersibles. Her work has been covered by Science Magazine, National Geographic, Atlas Obscura, and a David Attenborough-narrated documentary by Japan’s national broadcasting company, NHK.

Dr. Gerringer is committed to education and science outreach, including through experience teaching as a Fulbright Fellow in Bremen, Germany and serving as an onboard scientist on NOAA’s Okeanos Explorer, narrating telepresence-enabled exploration of the deep sea. 

At SUNY Geneseo, she teaches Animal Physiology, Marine Biology, and Science Communication.
