Research 

Generally, I am interested in how materials from land are dispersed and accumulate in the ocean, and how marine processes affect the coast and its resources.  I use sediment characteristics, environmental measurements (including oceanographic, meteorological, and hydrologic data), and geophysical methods like seismic-reflection tools to understand the modern and ancient processes influencing the seabed and sedimentary record of the coast.  This research is important to examining the fate of pollutants and runoff, assessing carbon sinks for climate studies, quantifying natural resources like sand for beach nourishment, evaluating biological habitats, identifying and extracting petroleum, and protecting our nation’s coastlines.

More specifically, the following are three general areas of research focus:

1)     Sediment movement and accumulation in the ocean.   A portion of my research focuses on understanding sedimentation along the continental margin, the portion of the ocean near land . These studies involve making ocean and seafloor measurements and collecting seafloor cores.  Lab and computer analysis help to determine sedimentation behavior. I have taken part in many offshore research cruises to support my investigations; here's an example expedition:   http://www.coastal.geology.ecu.edu/nz/.  

2)       River and estuarine  processes.  Materials from land are transport by rivers into estuaries.   Because these are critical ecological zones, it is important to be knowledgeable on how they function and be aware how humans may impact coastal biological, chemcial, physical and geological processes.  My research involves exploring and sampling coastal water bodies by small boat and uses a variety of research tools to measure different phenomena.  

3)     Shoreline and barrier island change.  Storms and sea-level changes are two key processes that can  alter the coast.   Our studies in North Carolina and around the world use remote-sensing methods (e.g., aerial photo analysis) and field investigations to help understand changes and potential ramifications.

Funding for my research has been provided by many grants from a variety of sources, such as the National Science Foundation, National Oceanic and Atmospheric Administration, the Albemarle-Pamlico National Estuarine Program (APNEP) and the State of North Carolina.


Teaching & Advising

I am currently the Director of the Summester at the Coast.

Classes I have taught include:
Atlantic Ocean and Mid-Atlantic Coast (GEOL2500/2501), East Carolina University/UNC CSI. This class reviews the history and oceanography of the Atlantic Ocean and examines the morphology of and processes affecting the mid-Atlantic region using North Carolina as an example. The focus extends from the Paleozoic to present and from the Appalachian Mountains to the Mid-Atlantic Ridge. The terrestrial, estuarine and oceanographic processes causing coastal change and associated sedimentation and stratigraphy are discussed. The class uses nearby depositional environments as context for the discussion, and the co-requisite lab (1 credit) involves related field trips.
Coastal Geoscience (GEOL 7002), East Carolina University, Class is designed primarily for doctoral students in the Coastal Resource Management Program.  Class uses lectures, labs and field trips to teach coastal geological and physical oceanographic processes
Oceanography (GEOL 1550), East Carolina University.  An introductory-level class with typical enrollment of ~100. 
Land-Sea Interactions (GEOL 6705), East Carolina University.  Created and orchestrated this graduate-level class including an overnight field trip.  Class was designed to educate students on quantifying sediment and solute dynamics; the Pamlico-Albemarle dispersal system is used as a focus.   
Sedimentology (GEOL 4010/4011), East Carolina University.  Lecture and lab class.  Prepared and presented lectures for upper-level undergraduate class.  Also, graded materials and coordinated exams, labs and field trips.
