Biography

Dr. Roeder's research interests broadly span biomaterials, including nanoparticles for targeted contrast agents and drug delivery, and scaffolds for regenerating tissues, as well biomechanics, including the mechanobiology and micromechanics of musculoskeletal tissues.  Dr. Roeder's research has been supported by the National Science Foundation (NSF), the National Institutes of Health (NIH), the U.S. Army Medical Research and Materiel Command (USAMRMC), the Congressionally-Directed Medical Research Programs (CDMRP), as well as private foundations and corporations.  Dr. Roeder’s research group is multidisciplinary, including students with backgrounds in biomedical engineering, materials engineering, mechanical engineering, chemical engineering, and chemistry.  Ph.D. graduates have been placed in postdoctoral positions, research hospitals, biomedical industry positions, and faculty positions.
