Dr. Andrew A. Wereszczak

Joint Faculty Professor

Ph.D., Delaware:  Mechanical Behavior, Science and Engineering of Ceramics, Glasses,and Brittle Materials

Brief Bio

Dr. Wereszczak earned his bachelor’s degree in Ceramic Engineering from Alfred University (Alfred, NY) in 1987, and his Ph.D. in Materials Science and Engineering from the University of Delaware in 1992. He presently is a Distinguished R&D Staff Member in ORNL’s Materials Science and Technology Division. He has worked at ORNL in two stints; from 2002 to the present and from 1991 to 2000. He worked at the US Army Research Laboratory from 2000-2002. Most of his professional career has been devoted to the characterization and modeling of the relationship between mechanical response of brittle materials and their microstructure. His work has contributed to the development of diverse sets of ceramics and other brittle materials considered for use in components for advanced gas turbine engines, internal combustion engines, glass manufacturing furnaces, armor, hybrid bearings, gun barrel liners, thermoelectric devices, power electronic devices, and photovoltaic cells. He has authored or co-authored over 175 publications including three book chapters, several patents and pending invention disclosures, has a copyrighted software program developed for microstructural-level thermomechanical modeling to his credit, has given over 100 presentations, and presently is an Associate Editor of the International Journal of Applied Glass Science. Dr. Wereszczak became a Joint Faculty Professor in early 2014.
