Executive Summary

Dr. Gillespie has served the University of Delaware Center for Composite Materials (UD-CCM) in several roles since 1981, achieving the position of Director in 1996. As director, Professor Gillespie has established an intellectually stimulating and highly interdisciplinary research environment for affiliated faculty, research professionals, graduate and undergraduate students, postdoctoral fellows, and visiting scholars to collaborate among themselves as well as with the Center's government and industrial sponsors. Dr. Gillespie has maintained a dedicated state-of-the art facility and maintains an open-lab philosophy to encourage participation in research and educational activities. Currently, more than 200 researchers are conducting more than 120 projects in composites-related fields. The funding for these projects comes largely from three prestigious DoD Centers of Excellence. Dr. Gillespie is the Principal Investigator of two Army Research Laboratory (ARL) Centers of Excellence, one in multifunctional composite materials and the other in mechanics and performance of composites. He is also co-principal investigator for a third Center of Excellence focused on advanced materials and intelligent processing funded by the Office of Naval Research (ONR). In addition, Dr. Gillespie is co-principal investigator for a fourth Center of Excellence, hosted by Wichita State University. Funded by the Federal Aviation Association, the FAA center focuses on advanced materials for commercial aircraft.

Building on traditional strengths and funding new initiatives, Dr. Gillespie has increased faculty participation to the highest levels in the Center's history with more than 40 faculty involved and advising graduate students in exciting new areas of basic research in multifunctional composites. Dr. Gillespie has maintained a commitment to undergraduate research by continuing the CCM undergraduate research program and expanding it to include an external internship at the Army Research Laboratory.

In 1996, Dr. Gillespie assumed leadership of the Center's University-Industry Consortium, “Application of Composite Materials to Industrial Products,” with only three members. Today, membership exceeds 60 companies—an all-time record. To meet the needs for applied research and technology transfer, Dr. Gillespie has incrementally expanded the number of research professional staff and the breadth of expertise in the Center's ranks. Today, research professionals visiting scholars, and postdoctoral fellows work closely with our industrial and government sponsors as well as the faculty and students. Dr. Gillespie has worked diligently to maintain an optimum balance of basic and applied research to ensure that CCM is not only at the forefront of the science of composites but also able to solve real-world engineering problems to benefit the Center's sponsors and society.

Prof. Gillespie is the Donald C. Phillips Professor of Civil and Environmental Engineering, and he also holds a joint appointment in the Department of Materials Science and Engineering. He has advised more than 29 PhD (23 completed) and 37 master's (36 completed) students as well as more than 100 undergraduate students (including 28 Science and Engineering Scholars from the University Honors Program). His former students have gone on to successful careers in academia (7 teaching at other universities), government, and industry. He was also chosen as the recipient of the Faculty Advisors Award from SAMPE in 2001. He was a Member of the National Science Foundation Task Force for Development of the first Doctoral Program at Tuskegee University. Today, he is an adjunct faculty member at Tuskegee, and he served on the dissertation committees of the first Ph.D. graduates at this Historically Black College.

Dr. Gillespie has a proven track record of conducting high quality basic and applied research in collaboration with colleagues from academia, government and industry. He has authored/co-authored more than 600 publications in composites science and technology including 11 book/book chapters, 15 patents, and more than 180 refereed journal papers, 300 proceeding papers and 100 technical reports. He has received over $70 million in funding to support his research and the Center overall.

Dr. Gillespie has served as a member of the prestigious and influential National Research Council Board on Manufacturing and Engineering Design, and Chair of the National Materials Advisory Board Committee on High-Performance Structural Fibers for Advanced Polymer-Matrix Composites. Dr. Gillespie has been Editor of the Journal of Thermoplastic Composite Materials since 1993, and he serves on numerous editorial boards.

Dr. Gillespie's contributions have been recognized through a number of honors and awards. He was a co-recipient of the U.S. Army's Paul A. Siple Memorial Award, announced at the 21st Army Science Conference in 1998, for his research on processing of multifunctional armor materials. His work on diffusion-enhanced adhesion for improved ballistics was cited in 1997 in the Department of Defense (DoD) booklet, Defense Basic Research-Rapid Transition from the Laboratory to the Field. The technology was one of only 17 examples of basic research recognized throughout the entire DoD. He was the first academic recipient of the prestigious Jud Hall Composites Manufacturing Award bestowed in 2000 by the Composites Manufacturing Association of the Society of Manufacturing Engineers (joining past-winners such as Burt Rutan and Brandt Goldsworthy). His research team was selected in 2004 by the American Composites Manufacturing Association for the Best of Show Award recognizing projects that are superior to all others in manufacturing, design, process innovation and use of composite materials. Dr. Gillespie has also received numerous best paper and best presentation awards over the years.
