About Dr. Denis Marcellin-Little
Upon graduation from Écoles Nationales Vétérinaires in France, Dr. Marcellin-Little completed his veterinary surgical training with a year-long internship in South Florida mentored by Dr. Jon Dee, followed by a small animal surgery residency at North Carolina State University (NCSU) mentored by Drs. Dan Richardson, Bill Betts, and David DeYoung. He joined NCSU’s faculty in 1993. During his 24-year tenure at NCSU, Dr. Marcellin-Little primarily collaborated with Drs. Simon Roe and Duncan Lascelles in orthopedics, with Dr. Ola Harrysson in engineering (biomodelling, medical 3D printing), and with Dr. David Levine in physical rehabilitation. After moving to the University of California-Davis eight years ago, he is now professor of orthopedic surgery, department chair, and co-director of the orthopedic lab.
Dr. Marcellin-Little maintains an interest in mechanistic and clinical research. His mechanistic research focus includes the study of chronic orthopedic pain and engineering approaches to analyze orthopedic problems and develop orthopedic procedures. His clinical research focuses on developmental orthopedic diseases, joint replacement, and the management of limb deformities.
Mentoring and collaborating are critically important to Dr. Marcellin-Little. He has mentored undergraduate students, veterinary medicine students, graduate students, interns, residents, and three ACVS Joint Replacement Surgery Fellows.
