His early work at JPL was on system design of large satellite-based systems for nationwide cellular phone coverage. He went to NASA Headquarters for two years in the mid-1980s to serve as the program manager for the Advanced Communications Technology Satellite (ACTS), the frontrunner of today's multi-beam, space-switching commercial satellites. Upon his return to JPL, he became the project manager for the NASA Scatterometer (NSCAT) project aimed at space-based radar measurement of winds over the global oceans with application to weather forecasting.
