Dr. Gray has a multifaceted career in which she has built programs to drive biomedical technology innovation, conducted research to better understand and prevent osteoarthritis, led a preeminent academic unit, and served the profession through work with organizations and institutions. Trained in computer science and electrical and biomedical engineering, and serving as an MIT faculty for three decades, she has held numerous leadership positions. For 13+ years, she directed the Harvard-MIT Division of Health Sciences and Technology (HST), an academic unit with multiple research and training programs for careers in medicine, business, and research. Dr. Gray currently directs MIT linQ which operates several multi-institutional ventures focus on accelerating and deepening early-career researchers’ potential for impact. Over the course of these efforts, she and her team have established a principled methodology for needs identification and opportunity development, and an organizational model that fosters a vibrant multi-stakeholder community necessary for sustained local and global impact.


Medical Devices; Biomedical Technology Innovation

Professor Gray’s current research builds on her experience directing HST and aims to establish validated approaches to accelerate biomedical technology innovation. Through a novel approach to research development that engages young talent and a diverse group of stakeholders from the academic, medical, and business sectors, she has spearheaded the development of numerous projects that have produced intellectual property flow at more than twice the volume and pace normally seen by MIT’s technology licensing office, brought numerous researchers into new areas, and attracted follow on funding through public and private sources.

Her extensive prior research was geared towards understanding and, ultimately preventing or slowing, the cartilage degeneration that affects at least 6 out of 10 people over age 45. Over the last decade, the efforts of Professor Gray and her colleagues have been primarily directed at establishing MRI tools that provide a picture of the biochemical and functional properties of the tissue. Specifically, they have developed and verified a method called dGEMRIC that indicates the amount of glycosaminoglycan (GAG) in the tissue. Regions of tissue that are functionally inadequate can be distinguished from normal tissue even when the entire tissue is anatomically intact (and looks normal with the usual imaging methods). They have also demonstrated that this imaging method can be used clinically (in vivo in humans) and for basic science studies of cartilage development. She and her colleagues have also shown that differences in GAG correspond with differences in mechanical (functional) tissue properties. This method is now available on musculoskeletal packages for MR systems and is used by numerous research groups around the world.
