Ali Sayir

Air Force Office of Scientific Research

Dr. Ali Sayir is currently the Program Manager for Materials with Extreme Properties portfolio within the Air Force Office of Scientific Research (AFOSR) in Arlington, VA. As a senior program officer Dr. Sayir has concerted effort on mathematic quantification of microstructures for DOD and leads major national programs in computational material science. He has responsibility for planning, directing, and securing long-term program support in extreme environment electronics and materials for quantum information sciences. As a Program Officer, Dr. Sayir proactively evaluates materials for extreme environments, and judiciously sponsors innovative scientific opportunities in materials that can be integrated in the ab-initio design process for far-from equilibrium effects, and extreme non- linearity’s, and ultra-fast control. He is in forefront in the development and execution of basic research on materials far from equilibrium for high-power systems and interested in new capabilities in materials that can adapt to external stimuli of electric-, magnetic-, acoustic-, thermal fields and combined loads. He is proactive member of DOD and scientific community, and coordinates research programs within the Air Force, DOD, and Army, Navy, DARPA, NASA and other national and international organizations.
Prior to joining AFOSR, Dr. Sayir managed materials and structures for NASA Hypersonic program at NASA Glenn Research Center, Cleveland, OH. He coordinated materials and structures projects between NASA centers, Department of Defense, Industry and Academia. Since 2008 he has held a Professor Faculty appointment at Case Western Reserve University in the Department of Materials Science of Engineering and has been founding member of a small company.
Dr. Sayir conducted research in areas such as eutectic solidification, electron emitters, high temperature piezoelectric materials, and materials for thermoelectric and thermophotovoltaic energy conversion, and proton conducting ceramics. He published 137 peer reviewed publications, 2 book chapters, received 3 patents, have over 40 invited presentations, and was selected a Fellow of the American Ceramic Society since 2009 for his scientific contributions and fellow of AFRL since 2020.
