Profile

Daniel Duffy, BVM&S, MS, FHEA, CertHE, MRCVS, Dip. ACVS-SA, Dip. ECVS

Assistant Professor Orthopaedic Surgery

djduffy@ncsu.edu

Dan attended veterinary school for 5 years the University of Edinburgh, Scotland where he obtained his veterinary degree with honors becoming a member of the Royal College of Veterinary Surgeons. He then worked with his parents for a short period of time in their small animal mixed practice. He then went on to complete a general rotating medicine and surgery Internship at Colorado State University (CSU). And then went on the complete an intensive 3 year small animal surgery residency and masters of science degree at Purdue University, Indiana.

Dan then spent two years as a clinical assistant professor of orthopedics, soft tissue and neuro surgery at the University of Illinois with a busy surgical (complex trauma) caseload. Dan became a Diplomate of the American College of Veterinary Surgeons (ACVS-SA) and shortly after became a Diplomate of the European College Veterinary Surgeons (ECVS). He also completed further training in education and advanced teaching and a certificate in education becoming a fellow of the Higher Education Academy (FHEA). He was recognized by the Royal College of Veterinary Surgeons (RCVS) and European board of specialization (EBVS) as a recognized specialist in the field of small animal orthopaedic surgery in 2018.

He has authored multiple publications in the area of canine tendon repair techniques and musculoskeletal models.
