Digges was the principal investigator on germanium crystal growth on the Skylab experiment in 1974 and worked at theJet Propulsion Lab from 1975-78, focusing on solar energy conversion. In 1978, he founded Virginia Semiconductor, a supplier of small-diameter and specialty-application silicon wafers. The company received the Photonic Spectra Circle of Excellence award in 1991, and in 1994, the prestigious Blue Chip Award given by the U.S. Chamber of Commerce and Connecticut for increasing its export business from 20% sales in 1986 to 40% sales in 1993.
Digges holds 10 patents, four trade secrets disclosures, and has published over 30 refereed technical publications.
