Dr. Patrick Louchouarn Biography:

Dr. Louchouarn completed a B.Sc. in 1989 in Marine Biology at McGill University (Montreal), followed by a M.Sc. in 1992 and a Ph.D. in 1997 at the University of Québec in Montréal in Environmental Sciences (geochemistry). His graduate research focused on understanding the cycling of trace metals (mercury) and terrestrial organic matter in freshwater and marine coastal systems.

From 1998-1999, he held a post-doctoral fellowship at the University of Texas-Marine Science Institute where he worked on dissolved organic matter cycling in the Arctic. He then held an Associate Research Scientist position at the Texas Engineering Experimental Station (Texas A&M) until the fall 2000 when he became Assistant Professor of environmental science at Texas A&M University – Corpus Christi. In 2002, he joined Columbia University and co-directed a new Master program in Public Administration at the School of International and Public Affairs. He was also appointed Associate Professor of aqueous geochemistry in Columbia University’s Dept. of Earth and Environmental Sciences. In 2006, Dr. Louchouarn joined Texas A&M University-Galveston/Texas A&M University as an Associate Professor of marine sciences and oceanography. He became Head of the Dept. of Marine Sciences in 2010 and Full Professor in 2011. He became Vice President for Academic Affairs and Chief Academic Officer for Texas A&M University - Galveston and Associate Provost for Texas A&M University on November 1, 2012.

Dr. Louchouarn maintains a multidisciplinary research program in environmental and organic geochemistry, especially as applied to understanding the impacts of environmental perturbations on biogeochemical cycling at ecosystem interfaces. The orientation of his research in biogeochemistry deals with 1) the identification of fire markers and combustion by-products in complex environmental mixtures and their application to reconstructions of fire/combustion history and 2) natural and human-induced fluctuations in material fluxes within watersheds. He has directly supervised 11 graduate and postgraduate students and has mentored more than 20 undergraduates in high impact research projects (including 8 senior theses) in his lab. Dr. Louchouarn has co-authored 50 manuscripts in the scientific literature. He has served as reviewer numerous grants for a variety of international, federal and local agencies as well as papers for numerous journals. He was awarded the 2010 Distinguished Achievement Award in Teaching by the Texas A&M University - Association of Former Students.
