His research interests focus on development and applications of in situ and operando synchrotron methods to solve a wide range of materials problems, with most recent emphasis on catalysis, electromechanical materials, filtration materials, quantum dots, physico-chemical properties of nanoparticles, as well as machine learning methods for structural analysis and design of nanomaterials. He is a founding Principal Investigator, co-director and the Spokesperson for the Synchrotron Catalysis Consortium at Brookhaven National Laboratory. He is a Fellow of the American Physical Society (APS) and American Association for the Advancement of Science (AAAS).
