MIAMI — April 26, 2011 — Danish marine biologist Martin Grosell, professor and associate dean of graduate studies for the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science was named 2011 “Best Student Supervisor of the Year” at UM. Sam Guffey, an undergraduate Marine Science student currently doing his senior thesis on fish intestinal transport processes in Grosell’s laboratory nominated him.

Grosell, whose research activities center on comparative physiology and aquatic toxicology, is studying how fish and invertebrates cope with environmental challenges including climate change and contamination. Guffey’s work is part of the Grosell teams’ studies on processes that allow marine fish to ingest and process seawater to maintain internal water balance. Grosell currently advises one postdoctoral fellow, four graduate students, and two undergraduate students in his research group.

“I was blessed with excellent mentors during my graduate and postdoctoral work,” said Grosell. “The common denominator between all of them was their enthusiastic support and guidance; yet, allowing me the freedom to pursue my own ideas, choose experimental approaches, and learn from my mistakes. I attempt to apply a similar strategy when mentoring and thoroughly enjoy interacting with the students in my lab.”

Guffey, who maintains a GPA of 3.91, won second place for “Best Student Presentation” at the Society of Experimental Biology in Prague, where he reported on his work on gulf toadfish in Grosell’s lab. His work is currently under review for publication in the American Journal of Physiology and he has been accepted into the Graduate Program at the Department of Biology at University of Alberta for fall 2011.

“Working with Dr. Grosell for the past two years has been a defining part of my UM experience,” said Guffey. “It has been great to see how science really works, including the challenges of collecting data and the rewards of presenting. Dr. Grosell was so supportive both at the lab bench and in helping me choose a career. Without this opportunity, I certainly wouldn’t be studying fish physiology, and I might not have chosen research at all, but now I can’t wait to work on the next big project.”

Grosell holds a Ph.D. in Toxicology and Physiology from the University of Copenhagen, where he also obtained his B.S. and MSc. He is a member of the Society of Experimental Biology and the Society of Environmental Toxicology and Chemistry.
