His group, the Princeton Lab for Electrochemical Engineering Systems Research, studies the interactions between materials and systems in electrochemical reactors with a focus on energy storage devices. His current research looks to exploit traditional failure mechanisms and "unwanted" interactions with batteries for systematic understanding and device enhancement. His efforts in this area over the last decade have been adopted by various industries and have led directly or indirectly to five energy related startup companies, the latest being Feasible, an effort dedicated to exploiting the inherent acoustic responses of closed electrochemical systems.
