BIO

Experience

2005 - Present

Consultant

Materials and Composites Solutions

Tallmadge, OH

Consulting, training, tutorials and expert witness in the areas of ceramic matrix composites and acoustic emission for national and international companies, universities and government agencies

2009 - Present

Professor

University of Akron

Akron, OH

Teaching and performing research in the Department of Mechanical Engineering. The focus of our research has been on elevated temperature performance of CMCs and EBCs in extreme environments as well as the development and implimentation of health monitoring techniques such as acoustic emission and electrical resistance for composites, metals, coating systems and structures.

1999 - 2009

Senior Research Scientist

OAI / NASA Glenn Res. Ctr.

Cleveland, OH

Part of a research team at NASA Glenn Research Center focused on the development of ceramic matrix composites with a focus on matrices and fiber-architectures towards higher elevated use temperatures in air-breathing aero applications.

1989 - 1999

Research Engineer

CWRU / NASA Glenn Res. Ctr.

Cleveland, OH

Part of a research team at NASA Lewis/Glenn Research Center focused on the development of ceramic matrix composite constituents (fibers and interphases) towards higher elevated use temperatures in air-breathing aero applications.
