Dr. Jeff Dixon is a Distinguished University Professor in the Department of Physiology and Pharmacology, and School of Dentistry at Western University in London, Canada. He studies the cellular and molecular mechanisms underlying the resorption and formation of mineralized tissues. Collaboratively, he is investigating mechanotransduction in skeletal cells and developing advanced materials for bone regeneration and dental applications. Dixon has served on the Advisory Board of the Institute of Musculoskeletal Health and Arthritis (one of the Canadian Institutes of Health Research, CIHR) and as president of the Canadian Association for Dental Research. From 2001-2009, he directed the CIHR Group in Skeletal Development and Remodeling, an interdisciplinary team focusing on musculoskeletal and dental health research. Dr. Dixon currently serves on the leadership team of the Bone and Joint Institute at Western University.
