Professor Karentz is a marine biologist with expertise in plankton ecology and ultraviolet photobiology. Her work has focused on investigating the ecological implications of Antarctic ozone depletion, specifically identifying strategies for protection from UV exposure and understanding mechanisms for repair of UV–induced damage. She has over 30 years of field experience in Antarctica.
In addition to research, Deneb mentors early-career scientists through the US National Science Foundation (NSF) International Training Program in Antarctic biology and the USF/UCSF Program in Mentoring and Teaching. She is also involved in environmental management and policy as a science adviser to the US Department of State for the Antarctic Treaty Consultative Meetings, and in her participation in the Scientific Committee on Antarctic Research.
