Michael Frohbergh, Ph.D.
Senior Associate
Biomedical Engineering
Philadelphia

Dr. Frohbergh’s expertise focuses on natural and synthetic biomaterials, in vivo biocompatibility and failure analysis of medical devices and implantable materials. He specializes in physical, chemical and mechanical characterization of biomimetic materials and tissue scaffolds and pre-clinical evaluation for tissue interaction and integration and performance. Dr. Frohbergh works closely with his clients from strategic planning and experimental design/testing through risk analysis and regulatory considerations. He also has extensive experience with 3D printing and additive manufacturing for biomedical applications and small animal models for wound healing, histology, cell and molecular biology techniques.

Dr. Frohbergh holds NAMSA ISO 10993 Series 1 certification for biocompatibility evaluation and risk assessment of medical devices. He also currently holds an adjunct professor position for the department of Biomedical Engineering, Science and Health Systems at Drexel University, where he has lectured on the regulatory issues and FDA framework related to stem cell therapies.

Prior to joining Exponent, Dr. Frohbergh earned his Ph.D. at Drexel University where his work focused on developing and characterizing an electrospun, crosslinked chitosan/hydroxyapatite scaffold for non-load bearing cranial bone regeneration, as well as its in vivo performance to induce wound healing. He then worked as a postdoctoral fellow at Icahn School of Medicine at Mount Sinai Hospital in the department of Genetics and Genomic Sciences where he evaluated articular cartilage repair using enzymatically treated cells in rodent models. While at Mount Sinai, he developed their rodent osteochondral defect model and protocol. He also worked on rare lysosomal storage disease mechanisms including mucopolysaccharidosis (MPS) and Farber disease. He was also involved in helping to develop the Mt. Sinai Institute of Technology (MSIT) and a mentor/assistant for the Design, Technology and Entrepreneurship (DTE) graduate classes.
