Beth G. Ashinsky, MD, PhD

Research Track

Medical School: Drexel University College of Medicine

Doctorate: University of Pennsylvania College of Biomedical Engineering

Undergraduate: Carleton College

Dr. Beth Ashinsky hails from Chappaqua, New York. Her path and interest in orthopedics was piqued at age 18 after an athletic injury that resulted in an ACL reconstruction. This allowed her to complete her freshman year of college as the starting varsity goalkeeper at Carleton College, where she graduated magna cum laude, obtaining her BA in Biology. In 2015, she completed a 2-year Intramural Research Training Award post Baccalaureate Fellowship with the National Institutes of Health. Immediately after, she joined the Magnetic Resonance Imaging (MRI) and Spectroscopy lab at the National Institute on Aging at Johns Hopkins Bayview, where she investigated a novel MRI classification technique using pattern recognition to characterize osteoarthritis and was awarded the F30 Ruth L. Kirschstein National Research Service Award. Beth completed her PhD in Biomedical Engineering at the University of Pennsylvania in 2020 where her research focused on establishing quantitative microscale and macroscale outcomes that define the spectrum of degeneration and to inform regeneration.  At Drexel School of Medicine, she was selected for Alpha Omega Alpha Honor Medical Society, Delta Zeta Chapter and served as the President of the Orthopaedic Surgery Interest Group. Beth is an ironman triathlon, and she enjoys weightlifting, road cycling, the food network, peloton and is a self-proclaimed sour beer enthusiast. Dr. Beth Ashinsky has spent her research year developing ideas for primary ACL repair. Working with Dr. Chris Ahmad and Dr. Stavros Thomopoulos, she is characterizing the cellular and extracellular makeup of ACLs, with an emphasis on the protective sheath that wraps around the ligament. This approach could be transformative in sports medicine for the care of ACL tears. Beth and her husband James Capon, MD (Hospitalist at Lenox Hill) are expecting their first son William Michael in May 2023!
