Biography

Wen Long grew up in Wangcheng District, suburb of Changsha City, Hunan Province, China. Northern Hunan is China’s heartland for farming and Wen, at his youth, was essentially growing rice year after year with his parents, during which he developed interests in studying the nature. In 1993, Wen was selected to go to Tianjin University for college majoring mechanics, where he also took electrical engineering as a minor, which helped him understand how computers work. Prof. Jianhua Tao introduced Wen Long into the field of hydrodynamics in 1995. Since then Wen has been working on applications of computational fluid mechanics with a focus on hydrodynamics. In 2000, Wen was admitted to The University of Delaware Center for Applied Coastal Research to study coastal and ocean engineering with a dissertation on wave and sediment transport under the supervision of Dr. James T. Kirby. During the 6 years at UD, Wen Long produced a suite of widely used water wave and sediment transport models, which are open source and bundled in CoastalSpace available on Source Forge. After graduation in 2006, Wen started applying his skills and knowledge in coastal ecological modeling. He was a postdoctoral fellow and later assistant research scientist at The University of Maryland Center for Environmental Science (UMCES), where he developed the Chesapeake Bay HAB prediction system, the community Chesapeake Bay Regional Ocean Modeling System (ChesROMS, Lead PI: C. Brown, R. Hood). Recently, Wen has also developed the following models for the Chesapeake Bay region: MACROMS--Mid Atlantic Coast Regional Ocean Modeling System; ChopROMS--Choptank River Regional Ocean Modeling System. These models are being used for studying blue crab larvae transport and oyster larvae transport supported by MD Sea Grant and US Army Corps. of Engineering (Co-PI with E. North). Wen Long is currently (2012) working on FVCOM modeling of the Puget Sound watershed integrated with the well celebrated CE-QUAL-ICM model. Wen Long continues his research collaboration with Chesapeake research community through an adjunct professor position at UMCES.
