Jonathan Seppala

Chemical Engineer

Jonathan Seppala is currently the technical lead in the additive manufacturing effort in the Polymer Processing and Rheology Project. His current research focuses on using infrared thermography, rheology, fracture mechanics, and neutron and x-ray reflectivity to study the polymer physics of thermoplastic additive manufacturing processes. Jonathan earned a B.S. in Chemical Engineering from Michigan Technological University and a Ph.D. in Chemical Engineering from Michigan State University studying the rheology and thermodynamics of polymer nanocomposites. Following his Ph.D., Jonathan worked as a Postdoctoral Researcher studying thin film self-assembly of block copolymers and equilibrium dynamics of amphiphilic micelles at the University of Delaware. Prior to joining the Polymer Processing and Rheology project, Jonathan studied ballistic witness materials and shear thickening fluids as part of the Personal Body Armor Project at NIST.
