Lloyd D. Keigwin studied geology at Brown University and oceanography at the Univeristy of Rhode Island. After graduating Brown he served on active duty for two years on a destroyer escort in Newport, R.I. and retired as Captain from the United States Navy Reserve in 1999. Keigwin's research interests focus on the ocean’s role in climate change on millennial and shorter time scales. In 2005, Keigwin became the first recipient of the Edna McConnell Clark Chair for Excellence in Oceanography, established for Clark's longtime support of WHOI. When not busy with family or having fun doing science, Keigwin works in his barn, trying to keep old sports cars running.
