Benjamin C. Streifel
Benjamin C. Streifel, Ph.D.
Senior Scientist
Polymer Science & Materials Chemistry
Bowie

Dr. Streifel has a diverse background working at the interface of chemistry, polymer science, and biomedical research. Dr. Streifel has experience with polymer synthesis, wound healing materials, drug release mechanisms, and stimuli-responsive materials. He specializes in the design, synthesis, and characterization of hydrogels, foams, block copolymers, and semiconducting polymers.

Dr. Streifel has utilized a wide variety of techniques for the design, synthesis, and characterization of polymeric materials, including spectroscopy (UV-Vis, FTIR, and Fluorescence), mechanical and thermal analysis (DMA, rheology, DSC, and TGA), chromatography (GPC, GC-MS, and HPLC-MS), microscopy (optical and SEM), and nuclear magnetic resonance spectroscopy (NMR). Dr. Streifel has synthesized a number of polymeric materials, and is familiar with catalytic cross couplings, emulsion-templated polymerization, free radical and controlled radical (RAFT) polymerizations.

Prior to joining Exponent, Dr. Streifel worked as a National Research Council Postdoctoral Research Associate at the Naval Research Labs in Washington, DC. While there, he designed, synthesized, and characterized materials for the treatment of severe wounds. Before working at the Naval Research Labs, Dr. Streifel’s Ph.D. research focused on the synthesis and characterization of semiconducting polymers for energy generation and spintronics applications.
