My primary interests involve many aspects of surface wave generation and propagation, including shelf-scale wave transformation, nonlinear wave-wave interaction, tsunami inundation, wave breaking and nearshore circulation, and the effects of various bottom types on the propagation and transformation of surface waves. Recently, I have started working on transport of contaminated sediments and water quality issues, and wetlands erosion in estuaries, with a specific focus on Galveston Bay and the Houston Ship Channel. I am also interested in data assimilation, and the ability to invert known or best-deduced dynamics to yield information such as bottom characterization parameters, input conditions and bathymetry. Generally, most of my work involves computational modeling; however, I have conducted laboratory tests at various facilities (Coastal Engineering Research Center at the U.S . Army Waterways Experiment Station; Texas A&M Coastal Engineering Laboratory; O.H. Hinsdale Wave Research Laboratory at Oregon State University) and have directed and participated in field instrument deployments (Nearshore Canyon Experiment at Scripps Institution of Oceanography; Al Ghariyah, Qatar) and post-disaster field surveys (Galveston Island / Bolivar Peninsula, TX after Hurricane Ike in 2008; Mexico Beach / Panama City Beach / Port St. Joe, FL after Hurricane Michael in 2018; Marsh Harbour / Freeport / Man O’ War Cay, Bahamas after Hurricane Dorian in 2019; and Ft Myers Beach / Sanibel Island / North Ft Myers / Ft Myers Shores, FL after Hurricane Ian in 2022).
