Bio. 

Extensive expertise with ocean and atmosphere numerical prediction models, proficient in multiple scientific programming languages, and experienced with analyzing large space-based and in-situ datasets in the GIS environment. Models used and adapted for weather and regional climate modeling include the Weather Research and Forecasting (WRF) model, Regional Ocean Modelling System (ROMS), the Coupled-Ocean-Atmosphere-Wave-Sedimentation Transport (COAWST) modeling system, and Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) Model. Programming languages applied in my research include: Python, Matlab, IDL, FORTRAN, BASH and C-shell.
