Research Description

Dr. Christopher Mendias is an Associate Scientist in the Orthopaedic Soft Tissue Research Program at HSS and an Associate Professor at Weill Cornell Medical College. Dr. Mendias received his undergraduate degree in Athletic Training and Biology, and a MS degree in Physiology at the University of Arizona. He then received his PhD in Molecular & Integrative Physiology at the University of Michigan, where he also completed his postdoctoral fellowship. Prior to arriving at the Hospital for Special Surgery, Dr. Mendias was an Associate Professor of Orthopaedic Surgery and Molecular & Integrative Physiology at the University of Michigan Medical School.

Dr. Mendias is a musculoskeletal physiologist who studies the cellular and molecular mechanisms of skeletal muscle and tendon growth and recovery from injuries. Studies in the Mendias Lab in skeletal muscle are focused on the cytokines TGF-b and myostatin in regulating muscle protein degradation and fibrosis, and studies in tendon mechanobiology are focused on the bHLH transcription factor scleraxis and its role in tendon stem cell biology, tissue regeneration and adaptation to loading. Dr. Mendias also conducts clinical trials focused on skeletal muscle atrophy and tendinopathy.
