Ph.D. Computational Sciences and Informatics, George Mason University, 2008; M.S. Applied Physics, George Mason University, 1997; B.A. Liberal Arts, St. John's College, 1993
I analyze data and create data visualization software to support NASA's Precipitation Processing System (PPS) at the Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. I have conducted research on tropical cyclones, isolated severe convective systems, and the precipitation climatology of arid regions.
--Analyze and visualize NASA's multi-satellite global precipitation-estimation algorithm (IMERG).
--Design and maintain a desktop and online data-visualization program (THOR) that allows researchers to examine the data products of NASA's Global Precipitation Measurement (GPM) mission.
--Reformat GPM data products from HDF5 to GIS friendly formats (e.g., GeoTIFF), virtual globe formats (e.g., Cesium, Google Earth), and NASA WorldView formats.
--During high-impact events, generate public-relations images and movies of NASA precipitation estimates combined with lightning flashes, model-estimated steering currents, infrared observations, wildfire locations, etc.
--Respond to questions about NASA precipitation estimation and tropical cyclones asked by researchers, members of the public, and the media.

|In the 2014, I was one of the scientists interviewed in a cable TV documentary called "Hurricane: The Anatomy". This documentary can currently be viewed on the CurosityStream.com video-streaming service. In 2012, I conducted an on-camera interview for an on-line video supplement to the weekly "Science Friday" radio program that airs on public radio. In that interview, I discussed 3D satellite-radar observations of Hurricane Sandy (2012) the day before it struck New York and New Jersey.|
