Jerome J. Nash, Ph.D.

Scientist
Polymer Science & Materials Chemistry
Bowie

Dr. Nash specializes in colloid and polymer characterization, with an emphasis on materials used for biomedical and food engineering applications. As a materials scientist, Dr. Nash leverages fundamental structure-property relationships to enhance the performance of complex fluids. Dr. Nash has diverse experience in the fields of emulsion science, polymer rheology, targeted drug delivery, enhanced oil recovery, and oil spill remediation. Dr. Nash’s current professional interests include polymer melt processing, industrial coatings, adhesives, pigments, and additives. In his role as a Scientist with Exponent, Dr. Nash utilizes his broad knowledge of polymer physics and failure mechanics to support clients in assessing end-use product performance.

Dr. Nash has employed a variety of techniques to characterize polymers, suspensions, and other soft materials, including mechanical techniques (shear and interfacial rheology, DMA), thermal analysis (DSC, TGA), surface roughness (contact angle hysteresis, AFM), spectroscopy (DLS, UV-Vis, FTIR), and microscopy (high-speed optical imaging, SEM). Additionally, Dr. Nash is familiar with common polymer melt processing techniques (such as injection molding, die pressing, and screw extrusion).

Prior to joining Exponent, Dr. Nash was a graduate researcher in the Soft Material Mechanics group at Purdue University. Dr. Nash conducted his doctoral research in materials science and engineering on the formulation of oil-in-water nanocapsule delivery vehicles for lipid-soluble bioactive compounds. Through his research, Dr. Nash developed tailored methods to improve the kinetic stability (i.e., shelf life) of emulsions, suspensions, and foams through modulation of the chemical and mechanical behavior of interface-adsorbing molecules. The methods and formulations developed through Dr. Nash’s research have been utilized in food engineering, enhanced oil recovery, and oil-contaminated waste water applications.
