Coastal Marine Sedimentology and Applications of High Resolution Marine Geophysics

Research Interests:

Quantification of the record of marine sedimentary processes using a combination of sediment analyses, short lived radio isotopes and high resolution marine geophysics.

Focus areas include:
- Coastal morphodynamics of the upper Texas shore face and inner shelf: (Galveston and Follett's Island,
 Matagorda Peninsula, Brazos River mouth, South Padre Island)
- Estuarine sedimentary processes and modern strata formation (Texas Bays: Galveston, Lavaca,
 Matagorda and Copano Bays; Naples Bay, FL; Chesapeake Bay,; Simpson Bay, Prince William Sound, AK)
- Geological record and response to extreme events- Hurricanes Claudette (2003), Katrina and Rita
