Bio
Jonathan Poplawsky received his Ph.D. in Physics at Lehigh University in 2012 where he built an apparatus capable of a simultaneous cathodoluminescence and photoluminescence experiment. During his studies, he received the Lehigh University “Graduate Student Teaching Assistant Award” and founded the Lehigh University Physics Graduate Student Association. Following his graduate studies, Jonathan worked as post-doctoral research associate in the Scanning Transmission Electron Microscopy (STEM) group at Oak Ridge National Laboratory (ORNL) under Stephen J. Pennycook. Following his postdoctoral studies, Jonathan received a strategic hire award from ORNL to implement new capabilities within the Center for Nanophase Materials Sciences Atom Probe Tomography (APT) laboratory, and expand the lab's research beyond metallic alloys, although alloys are still of great interest. His main research interests are focused on determining interfacial chemistry at the atomic level with the end goal of improving energy materials using Atom Probe Tomography. The material systems he works on are very diverse, including thin film solar cells, light-emitting diodes, battery technology, high temperature Al alloys, and energy efficient steels. Jonathan also excels with using focused ion beam, electron beam induced current, electron back scatter diffraction, cathodoluminescence, photoluminescence, and scanning transmission electron microscopy techniques.
