Jason leads the Photopolymer Additive Manufacturing project in the Applied Chemicals and Materials Division at the National Institute of Standards and Technology. His research develops novel measurement techniques to enable characterization of the vat photopolymerization process, in situ, with voxel and sub-voxel scale resolution. Methods reveal the presence and origin of micron scale defects and heterogeneities that limit adoption of vat photopolymerization for critical applications. Currently, Jason is deploying an atomic force microscope, modified with a digital light projection light-engine, to map photopolymer reaction in 3 dimensions. Jason is working closely with industry groups to identify gaps in existing measurement capability, and transfer new measurement technologies to industrial R&D and quality control. Jason has a Ph.D. in Chemical Engineering from the University of Washington and has been at NIST since 2009.
