As info Joe was flying Private at Corning when he joined Lightwave to help out, I think that he will be 80 soon so I can understand him stepping down and not wanting to stand in airports.
His guidance directed Lightwave to create a device lab alongside the chemical's lab for an instant feedback loop, one of the best calls ever.
Right transition, at the right time for Lightwave's commercialization. Bring the younger minds with more recent and applicable innovations in the polymer space closer to the decision zone at Lightwave.
Kudos to Joseph Miller for his service, and continued service on the Advisory board.
