Member of Technical Staff, April 1996-current,
Jet Propulsion Laboratory, Pasadena, CA

- Instrument Calibration, Design, and Development

• Used Modtran7 atmospheric transmission/radiance software to model effect of water vapor and aerosol concentration on reflected radiance. Assisted in defining instrument and algrorithm requirements for microspacecraft missions. Collected radiance data to assist with calibration of the AVIRIS instrument

Systems Engineer, 1992-1996,
Loral Infrared and Imaging Systems, Lexington, MA

- Instrument Design and Requirements Development

• Modeled effects of atmospheric conditions and surface reflectivity on sensor performance using Lowtran7 atmospheric transmission software. Assisted with analysis of requirements and initial instrument design for remote sensing instrument proposals.
• Developed model of scene and instrument-induced photon fluxes for the AIRS infrared atmospheric sounding instrument; model projected influence of optical transmission curves and optics temperatures on flux.
• Performed systems-level technical analysis for the THAAD missile seeker project. Analysis tasks included development of model calculating calibration temperatures for minimizing focal plane non-uniformity, an analysis of the impact of temperature stability on focal plane performance, and an examination of the influence of telescope alignment error on pointing accuracy. Assisted with the analysis of specifications and the evaluation of focal plane subcontractor proposals.

- Manufacturing and Reliability Analysis

• Derived and analyzed defect clustering statistics from focal plane test data; investigated methods of linking focal plane defect clustering statistics to a prediction of manufacturing yield.

Research Assistant, 1990-1992,
Brown University, Providence, RI

• Analyzed NASA Magellan radar images of Venus to develop geologic interpretations of steep-sided volcanic features; established database of features to quantify their characteristics and variation. First author of paper describing these previously unknown structures and their geological implications.

Research Assistant, 1989,
Jet Propulsion Laboratory, Pasadena, CA

• Wrote code to enhance images of oceanography data to assist in analysis of global ocean/atmosphere interactions.
