Research: Pathophysiology, epidemiology and treatment of orthopedic disease—osteoarthritis and fracture.
Osteoarthritis—The Reesink laboratory is actively investigating how synovial fluid glycans and glycoproteins, including lubricin and hyaluronic acid (HA), are altered in osteoarthritis (OA) and traumatic joint injury. The aim of this work is to understand how lubricin and HA synergistically enhance joint lubrication, mitigate inflammation and promote cartilage health, with the ultimate goal of developing novel therapeutic strategies for OA.
Fracture—The Reesink laboratory is examining the pathophysiology of fetlock fractures in racehorses through quantitative CT imaging and bone quality assessment. Long-term goals of this work are to develop clinically relevant methods of assessing fracture risk in equine athletes and to determine what epidemiologic factors are associated with increased fracture risk.
Clinical: Equine and farm animal orthopedic surgery; equine sports medicine and lameness.
Education and Training
- 2016 Cornell University, PhD in Comparative Biomedical Sciences
- 2012 Diplomate, American College of Veterinary Surgeons-Large Animal
- 2008-2011 Cornell University, Residency in Large Animal Surgery
- 2007 University of Pennsylvania, VMD (Summa Cum Laude)

Dr. Reesink received her veterinary medical degree (VMD) from the University of Pennsylvania in 2007. She came to Cornell for a large animal surgery residency from 2008-2011 and worked part-time as an Emergency Surgeon from 2012-2016 while completing her PhD in Comparative Biomedical Sciences. She was appointed Assistant Professor in the Department of Clinical Sciences in 2016.
Dr. Reesink is a Diplomate of the American College of Veterinary Surgeons with clinical interests in equine and farm animal orthopedic surgery, sports medicine and lameness. She is interested in translating novel research discoveries, including regenerative medicine and lubricin therapy, to equine clinical patients with musculoskeletal disease. Her laboratory investigates the pathophysiology, epidemiology and treatment of osteoarthritis and racehorse fractures.
In her free time, Dr. Reesink enjoys outdoor activities, including running, cycling, and horseback riding.
