About Us

MarkI'm an engineer (B.S., Notre Dame) with many decades of successful experience in solar energy and related technologies. (Not bad for a 35-year-old guy!)

I've authored or co-authored over 200 technical publications (click on link for Publications to see some), including U.S. Patents on 23 inventions (click on link for Patents to see them) and three textbooks. My specialties are solar energy, daylighting, and ultra-bright traffic stripes.

I've proposed, won, and managed many significant contracts funded by DOE, NASA, NREL, DOD, the National Academies, utility companies, aerospace companies, and others.
