Tian-Jian Hsu (Tom) is currently Professor of Civil and Environmental Engineering, and Director of Center for Applied Coastal Research at the University of Delaware (UD). Before joining UD, he was an Assistant Professor of the University of Florida (2006~2008) and Assistant Scientists at Woods Hole Oceanographic Institution (2004~2006). Hsu earned a bachelor degree (Ocean Engineering) from National Taiwan University in 1994 and a PhD degree (Civil Engineering) from Cornell University in 2002. He received the NSF Early Career Development (CAREER) Award in 2007. Between 2015 to 2019, he served as an executive committee member of Community Surface Dynamics and System (CSDMS) and was elected to be the Chair of Cyberinformatics and Numerics Working group of CSDMS in 2015. He served as Associate Editor of Journal of Geophysical Research: Oceans between 2011~2019. Hsu is a member of the American Geophysical Union and American Society of Civil Engineers,

Hsu’s main research covers numerical modeling/simulation of various non-cohesive and cohesive sediment transport, including wave-driven on/offshore transport and their effect on beach profile evolution, and flocculation of cohesive sediments. More recently, his research focused toward heterogeneous sediment processes, such as size grading, interaction of mud, sand and oil droplets, and evolution of bedforms. His group devoted major efforts to develop open-source numerical tools for sediment transport in the OpenFOAM framework as well as a new pseudo-spectral scheme for turbulence-resolving fine sediment transport in bottom boundary layers.
