    Postdoctoral Training, University of Vermont

    PhD, Columbia University





    Dr. Iatridis is Professor and Director of Spine Research in the Leni and Peter W. May Department of Orthopaedics at the Icahn School of Medicine at Mount Sinai in New York City.

    Dr. Iatridis graduated from Franklin and Marshall College with a B.A. in Physics, and then completed his B.S., M.S. and Ph.D. from Columbia University in Mechanical Engineering with Dr. Van C. Mow as his graduate mentor. Following his graduate studies, Dr. Iatridis was a post-doctoral fellow in the Department of Orthopaedics & Rehabilitation at the University of Vermont under the guidance of Dr. Ian Stokes. Dr. Iatridis became faculty in the School of Engineering at UVM in 1999, retaining a joint appointment in Orthopaedics & Rehabilitation, and going through promotion to full professor. He has also been Visiting Professor at the AO Research Institute in Davos Switzerland working with Mauro Alini and Adjunct Investigator at the Cartilage Biology and Orthopaedics Branch of the NIH in Bethesda, MD, working with Rocky Tuan.


    Dr. Iatridis’ research focus is on the development of early and minimally invasive treatments to prevent or repair injured and degenerated intervertebral discs.  He has investigated problems in the intervertebral disc since 1994, and has published over 60 papers in the field of orthopaedics. Dr. Iatridis received grants from the NIH, Whitaker Foundation, and AO Foundation. He was awarded a Presidential Early Career Award for Scientists and Engineers (PECASE) in 2008, and the Berton Rahn Research Prize of the AO Research Fund in 2009. Dr. Iatridis is very active in his research community having reviewed for over 20 journals and 6 funding agencies, he currently serves on the editorial board of 2 journals and as a member of the NIH Skeletal Biology Structure and Regeneration Study Section.

    Our laboratory is interested in investigations of functional changes in the spine in response to loading and injury, and investigations of promising therapeutic techniques to promote spine health and repair. Our investigations span biomechanics, mechanobiology, tissue engineering, anti-inflammatory and cellular therapies. Through our animal, cell, and organ culture studies we have a focus on models of injury and repair with high relevance to human clinical conditions. Our research balances exploration of fundamental mechanisms and translation with appreciation for the development and maturation processes in human joints that promote health and disease processes.
