Alan Eberhardt's major interests lie in two areas: orthopedic biomechanics and injury biomechanics. He has a history of study related to total joint replacements involving biomechanics and biomaterials, including surface treatments, implant tribology, implant design, and forensic analysis. His experience with the study of biomechanical response of the pelvis in automotive side impacts and in the presence of metastatic bone lesions includes both experimental and computational (finite element) biomechanics. He also serves as PI on NIH and NSF funded grants aimed at facilitating undergraduate designs of biomedical devices, including those to aid persons with disabilities.
