Encyclopedia
Donal Thomas Manahan is an Irish-born
American marine scientist and comparative physiologist
known for Antarctic and deep oceanic research on the physiology and ecology of marine invertebrates
and their larvae in extreme environments.
in Bangor, Wales
, where he earned his Ph.D. studying in the laboratory of Dennis J. Crisp. From 1980 to 1983, he was a post-doctoral fellow in the laboratory of Grover C. Stephens
at the University of California at Irvine. Manahan joined faculty at the University of Southern California
in 1983.
Manahan has served as Chairman of the United States National Academy of Science Polar Research Board and he served on the National Science Foundation
(NSF) Decadal Group-Planning Committee for Ocean Sciences (2000). He has also served on NSF Federal Advisory Committees to the Director from NSF's Office of Polar Programs. Manahan Peak
in Antarctica was named in honor of his contributions to research and education on that continent.
Republic of Ireland
Ireland , described as the Republic of Ireland , is a sovereign state in Europe occupying approximately five-sixths of the island of the same name. Its capital is Dublin. Ireland, which had a population of 4.58 million in 2011, is a constitutional republic governed as a parliamentary democracy,...

Comparative physiology
Comparative physiology is a subdiscipline of physiology that studies and exploits the diversity of functional characteristics of various kinds of organisms. It is closely related to evolutionary physiology and environmental physiology. Many universities offer undergraduate courses that cover...

Marine invertebrates
Marine invertebrates are animals that inhabit a marine environment and are invertebrates, lacking a vertebral column. In order to protect themselves, they may have evolved a shell or a hard exoskeleton, but this is not always the case....

Education and career
Donal Manahan was educated at Trinity College Dublin and the University of WalesUniversity of Wales
The University of Wales was a confederal university founded in 1893. It had accredited institutions throughout Wales, and formerly accredited courses in Britain and abroad, with over 100,000 students, but in October 2011, after a number of scandals, it withdrew all accreditation, and it was...
