Committee Biographical Information

Joseph G.Wirth, Chair, retired as senior vice president and chief technical officer at Raychem Corporation, where he served as manager of worldwide technology with responsibility for corporate manufacturing and new business development. Dr. Wirth integrated new business directions into Raychem’s existing manufacturing structure. Previously, he had worked at General Electric (GE), where he served as technology leader for the silicones business and vice president of the technology division for GE’s plastics business. He is the inventor of polyetherimides, a fire-resistant plastic used in aircraft interiors and other industrial and consumer applications. He holds various patents in the high-performance polymer area and is the author of numerous publications. Dr. Wirth has served on several National Research Council (NRC) committees, including as chair of the Board on Manufacturing and Engineering Design and as a member of the National Materials Advisory Board.

Viola L.Acoff is associate professor in the Department of Metallurgical and Materials Engineering at the University of Alabama, where she has taught for 10 years. Dr. Acoff teaches courses in welding metallurgy, physical metallurgy, and scanning electron microscopy. Her research interests include the following: the microstructural evolution of the fusion- and heat-affected zones; high-temperature materials; electron microscopy; weldability and computer modeling of advanced materials; the effect of orientation on weld properties; indentation behavior of materials, particularly joining and interfacial structures; processing of alloys by cold-roll bonding; and the evaluation of contact angles of lead-free solders on copper substrates. Dr. Acoff is the recipient of numerous national and international awards, including the Adams Memorial Membership Award (2000), presented by the American Welding Society; Best Paper Award for TMS (The Minerals, Metals, and Materials Society) Symposium on Gamma Titanium Aluminides (1999); TMS Young Leader Intern (1998); National Science Foundation CAREER Award (1997); Warren F.Savage Memorial Award (1996), from the American Welding Society; International Business Machines Award for Excellence (1992); and First Place Award for Best Physical Sciences Paper (1991), from the Microscopy Society of America. Dr. Acoff is active in professional societies, including the American Welding Society, TMS, and ASM International.

Alexis G.Clare is a professor of glass science at Alfred University. Her research interests include relationships of structure and optical properties in glasses, biological applications of glasses, optically active glasses, and the structure of glasses by neutron and X-ray diffraction. She is the author or co-author of more than 65 published papers and 6 book chapters, and the editor of 3 books. She also holds a U.S patent. Dr. Clare has been active in many professional societies, serving as president of the National Institute for Ceramic Engineers (2003) and chair of the Glass and Optical Materials Division of the American Ceramic Society (1998). She is a fellow of both the United Kingdom’s Society of Glass
