Jill N. Baxter
Senior Associate
Biomedical Engineering
  • Philadelphia

Ms. Baxter is an experienced laboratory operator who focuses on evaluation of biomaterials and medical devices. She is the technical lead for the following capabilities in the Philadelphia laboratory: microCT, FTIR, corrosion testing, and particle analysis. She is a trained operator of the scanning electron microscope at the University of Pennsylvania. Ms. Baxter has experience evaluating a range of medical devices including but not limited to orthopedic implants, breast implants, and cardiac devices. She is biohazard trained and has worked extensively with cadaver and animal tissue testing.

At Exponent, Ms. Baxter developed capabilities for analysis of implant coatings. For hydroxyapatite specifically, she developed protocols for performing the full battery of testing required by the FDA Guidance Document, including accelerated aging, wet chemistry analysis, FTIR, XRD, particle analysis, and solubility and dissolution testing. Ms. Baxter serves on ASTM F04.13 Subcommittee for Ceramics Materials and is collaborating with the FDA to drive the development of new standards in this area.

Ms. Baxter serves as the Documentation Manager for Philadelphia’s ISO 17025 and GLP accredited laboratory. She developed and implemented an electronic documentation management system that seamlessly connects procedure development, operator training, equipment and supply management, and testing records.

Ms. Baxter earned her graduate degree from the University of Pennsylvania, where she was awarded a fellowship from the Center for Technology Transfer. Her primary responsibility was to evaluate the potential for commercialization of inventions from the engineering and medical schools through literature reviews and patent searches. As a part of this fellowship, she also completed graduate coursework in technology transfer and commercialization of medical devices.
