Clare Rimnac received a B.S. in Metallurgy and Materials Science from Carnegie-Mellon University in 1978, and an M.S. in 1980 and a Ph.D. in 1983 in Metallurgy and Materials Engineering from Lehigh University. In 1983, she was a Research Fellow and from 1984 until 1996 she was a Scientist in the Department of Biomechanics at The Hospital for Special Surgery in New York City. In 1996, Professor Rimnac joined the faculty of the School of Engineering at Case Western Reserve University where she is currently the Wilbert J. Austin Professor of Engineering and Associate Dean of Research in the Case School of Engineering. She holds secondary appointments in Biomedical Engineering and Orthopaedics.

Professor Rimnac’s research is funded by the NIH, private foundations, and industry and is directed towards orthopaedic biomechanics, with a focus on lifetime and degradation science of medical devices and materials, including: implant retrieval analysis; mechanical behavior and modeling of materials used in total joint replacements; and damage and fracture behavior of bone tissue. She has published more than 150 peer-reviewed articles and book chapters.

Among other honors, Professor Rimnac has served on two NIH study sections, is the recipient of an American Academy of Orthopaedic Surgeons Kappa Delta Award, two Hip Society Awards, and a Knee Society Award. She has served as a Deputy Editor for the Journal of Bone and Joint Surgery and was President of the Orthopaedic Research Society.  In 2013, she received the  Women's Leadership Award from the Orthopaedic Research Society.

Professor Rimnac currently serves as a Senior Associate Editor for Clinical Orthopaedics and Related Research.  She is a member of external adivsory board for the Bioengineering Program at Lehigh University.  In 2014, she was elected to the board of the Engineering Research Council of ASEE.
