Stephen C Purdy

R&D associate staff scientist

Dr. Stephen C. Purdy is an associate R&D staff scientist in the Chemical Process Scale-Up Group in the Manufacturing Science Division of Oak Ridge National Laboratory. He obtained his PhD at Purdue University in 2019 and spent three years as a post-doc at Oak Ridge National Laboratory in the Powder Diffraction Group in the Neutron Scattering Division before joining as a staff member if 2022. His interests lie in structural characterization of catalysts under working conditions using X-ray and Neutron methods, developing new sample environments for in-situ and operando X-ray/neutron characterization, catalyst synthesis/formulation, and the transformation of renewable-derived feedstocks for sustainable fuel and chemical production.
