Behrad Koohbor received his Ph.D. in mechanical engineering from the University of South Carolina in 2016. He is currently a member of the Autonomous Materials Systems (AMS) Group at the Beckman Institute for Advanced Science and Technology. Behrad’s appointment is split across two research programs: (1) Characterization of the mechanical response of polymers and polymer composites developed in AMS at Illinois. This work is a part of self-healing/regeneration project supported by Air Force Office of Scientific Research (AFOSR). (2) Measurement and characterization of stress and strain fields in new Li-ion solid state battery materials. This is a collaborative project between several institutions (Argonne National Laboratory, Illinois, Northwestern and Purdue) through the CEES program supported by the U.S. Department of Energy.
