Dr. Trelewicz’s research explores the science of interface engineered materials for extreme environments using advanced processing and characterization tools coupled with multi-scale modeling and simulation. Professor Trelewicz received his Ph.D. in Materials Science and Engineering from the Massachusetts Institute of Technology in 2008.  Prior to joining Stony Brook University, he spent four years as Research Director at MesoScribe Technologies, Inc.  Professor Trelewicz is a recipient of the DOE Early Career Award (2017) and NSF Faculty Early Career Award (2016).  His work on ceramic composite moderators was selected by the Journal of Nuclear Materials for the 2022 Best Paper Award, and he also co-authored a manuscript selected for the 2022 Journal of Asian Ceramic Societies Best Paper Award.  Professor Trelewicz was recognized by Long Island Business News Power 25 in Education as a Top Innovator in Energy Research and Stony Brook University as a 40 Under 40 Honoree.  He received the Fusen and Yijen Chen Prize for Innovative Research in 2018 and Young Leader Professional Development Award from the Minerals, Metals, and Materials Society (TMS) in 2015.
