Dr. Mason is trained as a polymer chemist and materials scientist, with specialized experience in photo-curing polymers, additive manufacturing, chemical recycling, and polymer synthesis. He leverages broad expertise in formulation, synthesis, and analytical techniques to consult on a variety of projects, with an emphasis on failure analysis, materials compatibility, composition, and performance optimization.

Dr. Mason has extensive experience with polymer characterization and analytical techniques, including nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), rheology, tensile testing, and other spectroscopic methods.

Prior to joining Exponent, Dr. Mason earned his Ph.D. in Chemistry from the University of Texas at Austin. During his doctoral work, he was recognized with awards such as the UT Austin Discovery to Impact Proof of Concept Award and held an internship at Sandia National Laboratories. His research focused on development of novel photopatterning techniques for multi-scale control of polymer architectures, with applications in critical resource recovery and automation of additive manufacturing.
