Jon Cohen's research includes pelagic ecology, deep-sea biology, and polar biology. He is interested in how environmental factors influence marine animal physiology and behavior, with many of his projects focusing on sensory biology of marine invertebrates.

Congratulations to Corie Charpentier and Alex Wright for each receiving a Grant-in-Aid of Research from Sigma Xi to support their research!
Jon is currently on Svalbard conducting research into light and vision in the polar night. Learn more at the UDaily series "A Tale of Two Poles" and in The News Journal.
Our DESG-funded zooscan project has been featured in UDaily, WDDE radio, The Coast Press, The News Journal (with graduate student Adam Wickline on the front page!), and WHYY First.
Jon participated in a symposium on Polar Night biology at the Arctic Change 2014 meeting in Canada. More details on this and other presentations can be found on the Mare Incognitum website.
Our DSG ZooScan project was featured in the Environmental Monitor.
EPSCOR Summer Scholar and UD senior Hayley DeMarchis won an EPSCOR science ethics essay contest. Congratulations, Hayley!
Former UDRF REU student and UD Junior Alex Wright was selected as a NOAA Hollings Scholar for 2014-2016. Congratulations, Alex!
