Falmouth, Massachusetts, United States
Summary
👤
Senior🎓
Top SchoolZafer Defne is an oceanographer with over a decade of applied experience solving coastal and estuarine engineering problems using hydrodynamic modeling and geospatial analysis. At USGS he has implemented 3-D models of circulation, waves and sediment transport, led multi-group efforts to publish FGDC-compliant geospatial data, and assessed wetland vulnerability to storms, contamination and sedimentation. His technical toolbox spans COAWST/ROMS, ArcGIS, Python/Matlab/FORTRAN, netCDF/NCO and parallel MPI workflows, enabling end-to-end data processing from LiDAR/bathymetry integration to large-scale model runs. He contributed to DOE-funded tidal energy resource assessments and built interactive mapping and GIS server solutions that translated complex model output into usable decision tools. Known for marrying field measurements and numerical models, Zafer also automates repetitive geospatial tasks with scripting to accelerate reproducible science. Based in Falmouth, MA, he combines rigorous academic training (PhD, Georgia Tech) with practical government research experience to inform coastal resilience and renewable energy planning.
