Ph.D. Student

Research Interests

My research focuses on advanced GIS/RS technologies and their use for mapping and modeling geomorphologic processes in coastal environments. My dissertation project uses in-situ data, multispectral satellite imagery, and computer programming to determine the spatio-temporal variation of rip current hazards in Costa Rica and Australia. I anticipate completing my Doctorate by Fall 2016.

My employment and education have focused on research design, GIS/RS, academic publishing, programming ArcGIS extensions, and teaching. In addition to my education, I have worked as a geospatial analyst for the Department of Homeland Security (OCIO), the US Geological Survey, and NASA (Langley). Upon completing my degree, I intend to return to a professional position that includes solving problems with a combination of field work, remotely sensed data, and computer modeling.

Specialties: Coastal Geomorphology, Geographic Information Science and Theory, Remote Sensing & Air photography interpretation, Field experiment design and execution, and Python programming for GIS analysis
