He received M.S. and Ph.D. degrees in Materials Science and Mechanical Engineering from the University of Washington, Seattle, Washington, and a B.S. in Materials Science from the University of Cincinnati, Cincinnati, Ohio.
Currently, he is a Materials Research Engineer in the Ceramic and Polymer Composites Branch. His duties at GRC included Deputy Branch Chief of the Life Prediction Branch (July 2003-October 2003), Materials Research Engineer in the Life Prediction Branch (September 1996–June 2003), Project Leader for Toughened Ceramic Life Prediction (June 1987 to August 1996), and Materials Research Engineer in the Fatigue and Fracture Branch (June 1983 to May 1987). Prior to NASA, he worked in Quality Assurance at Powell Valve, Cincinnati, Ohio, and at Forest City Foundries, Cleveland, Ohio (March 1980 to June 1981).
He has authored or co-authored over 135 archival publications and six national or international standards on mechanical testing of ceramics. He is a fellow of ASTM, received a NASA Manned Space Flight Awareness Award, and a Federal Laboratory Consortium Award for Excellence in Technology Transfer.
As a member of the Engineering Ceramics division, he served as chair and received the Fulrath award along with Technical Presentation First and Second Prizes.
Current interests include mechanical testing, behavior and reliability analysis of ceramics, glasses and optical materials for structural applications, with current emphasis on crack growth behavior of transparent ceramics such as silicates and spinel.
