Honors and awards
Dr. Johnstone received the Marshall R. Urist MD Award in 2017. This prestigious award, sponsored by the Journal of Orthopaedic Research (JOR), honors an investigator who has established him/herself as a cutting-edge researcher in tissue regeneration research and has done so with a sustained ongoing body of focused research in the area of tissue regeneration as it relates to the musculoskeletal system.
In March 2018, Dr. Johnstone was inducted into the inaugural class of ORS Fellows. The ORS Fellows Program recognizes individuals who have demonstrated service and leadership, substantial achievement, expert knowledge, and significant contributions to the field of musculoskeletal research and the Orthopaedic Research Society (ORS). Fellows represent the ORS as the thought leaders and topic experts in their respective disciplines. Fellows will also serve as role models in the ORS membership community and in the field of musculoskeletal research.
