“I have worked with Exothermics and have known Steve for over 15 years. He was trained as a metallurgist, but has considerably broadened his knowledge to encompass additional spheres of materials including ceramics, ceramic composites, carbon-carbon composites, and associated coatings. He is one of the smartest materials scientists I have had the pleasure of knowing – he is always learning, digs into the literature of the past, and is creative in developing new materials and fabrication approaches.”
