Justin M Gorham (Fed)

Research Chemist


Justin M Gorham is a Group Leader and research chemist in the Nanomaterials Research Group at NIST. Dr. Gorham received his bachelor’s degree in chemistry from Bates College in Lewiston, Maine in 2003 and his PHD in surface chemistry from the Johns Hopkins University in 2008.  He was awarded a position as an NRC postdoctoral fellow at the National Institute of Standards and Technology in 2009 to study environmentally induced transformations to the surface chemistry and stability of nanomaterials.  He became a research chemist in 2011 and a group leader in 2018.  Dr. Gorham currently works on research involving nano-enabled products, microplastic and nanoplastic metrology, standards development (both physical and documentary), and developing/applying surface chemical characterization methodologies especially with respect to the MMSD XPS facilities
