John R. Hoffman

B.Sc., University of Toledo, USA, 2016

Ph.D., University of Notre Dame, USA, 2021

John obtained his PhD in Chemical Engineering from the University of Notre Dame. His research focused on membrane separations and adsorptive materials, studied via the modification of porous polymeric materials through rapid functionalization reactions. His work at ISTA utilizes these skills to examine contact electrification of ionomer films to further understand the fundamental phenomena behind the triboelectric effect.
