Glass Materials, Mass Transport, Reliability

Professor Tomozawa received a Ph.D. degree in metallurgy and materials science from the University of Pennsylvania in 1968, after working for the Nippon Electric Company for four years. He joined the faculty at Rensselaer in 1969. He has published extensively in the area of glass science and edited several books on the subject. He served as the Chair of the Glass and Optical Materials Division of the American Ceramic Society and is a fellow of the American Ceramic Society.


Ph.D. Metallurgy and Materials Science (University of Pennsylvania, 1968), B.S. Electrochemistry (Yokohama National University, Japan, 1961)
