Joseph Vrabel

Biography

Bachelor of Science, Mathematics with Physics minor (2000) Virginia Polytechnic Institute & State University

 

Performed computer modeling and data analysis using industry-standard software in the areas of surface- and groundwater flow, watershed simulation, contaminant/sediment transport, and surface geophysical data acquisition. Developed mathematical methods and wrote custom software when commercially available tools were inadequate or nonexistent. Collected pertinent field data to evaluate developed software and obtain critical results. Authored and published technical papers detailing the methods, results, and findings. Prepared user manuals for the software and maintained a web-based central repository for distribution within the USGS scientific community (accessible on the USGS intranet at: http://tx.cr.usgs.gov/jvrabel/). Actively maintained and enhanced the software based on feedback from the user community.
