Biography


LTC Jeremy Hershfield, Ph.D., is in his second rotational assignment as an Assistant Professor within the Department of Chemistry and Life Science. In addition to teaching General Chemistry and Biochemistry, he serves as the head Departmental Academic Counselor. He is also an Adjunct Assistant Professor within the Molecular & Cell Biology program at the Uniformed Services University of the Health Sciences (USUHS).

After commissioning from Cornell Army ROTC, LTC Hershfield earned his doctorate in Molecular & Cell Biology at USUHS. As a 71B Biochemist in the U.S. Army Medical Service Corps, LTC Hershfield’s military experience includes public health analytical chemistry and previous teaching at West Point, as well as leadership and collaborative research and management roles within DoD hospitals, funding agencies, and U.S. Army Medical Research and Development Command (USAMRDC) research laboratories.

LTC Hershfield is a Science and Technology Manager (S&TM) Defense Acquisition University (DAU)-certified acquisition professional. He has earned U.S. Army additional skill identifiers in the areas of 6z (Strategic Studies) and 8x (Army Medical Department Acquisition).

Ongoing Research Projects


In collaboration with the Albert Einstein College of Medicine, LTC Hershfield is the PI for “Screening for Therapeutic Monoclonal Antibodies Against Powassan Virus.” Powassan virus (POWV) is a tick-disseminated flavivirus that causes severe encephalitis, meningitis, and long-term neurological damage. Although POWV infections are relatively rare, the virus is widely distributed among common vectors such as Ixodes scapularis (the deer tick), which also carries the bacteria that cause Lyme Disease, and the number of reported cases in the U.S. is rising each year. There are no approved vaccines or treatments for POWV infection. In this project, LTC Hershfield’s research group surveys serum repository samples to determine the overall level of POWV seropositivity among previous USMA cadets. Future efforts will include a clinical study to actively assess seropositivity rates among cadets and isolate and evaluate antibodies as potential therapeutic options for treating POWV infections.

LTC Hershfield is also PI on a DTRA-funded bioprinting research project, “Understanding Performance Characteristics of Novel 3D-Bioprinted Bandages.” Primary battlefield injuries involve blood loss, infection, or loss of tissue viability and typically require hemostatic dressing and tourniquets to facilitate patient movement to subsequent care. 3D bioprinting is an emerging technology that can enhance and expand bioactive bandage capabilities through precise, repeatable positioning and dispensing of cells and other biomolecules in a three-dimensional layering. Exosomes are a low-cost, readily available subset of extracellular vesicles, which are promising therapeutic options for wound healing via encapsulated immune-enhancing molecules. In this effort, cadets 3D-print hydrogels, embed them with fluorescently tagged exosomes and/or cells (such as Histone H2B-GFP expressing HeLa Cells), and evaluate their release properties and mechanical characteristics to simulate wound therapeutic applications.
