Gary L. Messing is Distinguished Professor Emeritus of Ceramic Science and Engineering and former Head of the Department of Materials Science and Engineering, and co-Director of the Center for Innovative Materials Processing by Direct Digital Deposition (CIMP-3D) at the Pennsylvania State University. He served as Director of the Materials Research Laboratory at Penn State, and was Founding Director of the NSF Industry/University Cooperative Research Center on Particulate Materials at Penn State.

Dr. Messing received a B.S. degree in Ceramic Engineering at the New York State College of Ceramics at Alfred University in 1973 and a Ph.D. in Materials Science and Engineering at the University of Florida in 1977.

He has published over 300 papers and co-edited 13 books.  He is interested in improving ceramic materials for optical, piezoelectric and structural applications by regulating microstructure evolution using innovative approaches, including seeding of phase transformations, sintering stress analysis, and templated grain growth.  He was Editor in Chief of the Journal of Materials Research from 2009-2022.

Professor Messing received the Wilson Research and Outstanding Service Awards of the College of Earth and Mineral Sciences at Penn State.  He received the Robert Sosman, Edward Orton and John Jeppson awards of The American Ceramic Society and the Richard Brook award of the European Ceramic Society.  Messing was elected Fellow of The American Ceramic Society, the Materials Research Society and as an Academician of the World Academy of Ceramics.  He was named Distinguished Life Member of The American Ceramic Society in 2013 and served as President of the Advisory Board of the World Academy of Ceramics.
