Warren Grayson

Associate Professor
Johns Hopkins University School of Medicine

Warren Grayson, Ph.D., is an Associate Professor in the Department of Biomedical Engineering at Johns Hopkins. Prior to coming to Johns Hopkins, Grayson was a Postdoctoral Fellow at Columbia University. He received his Ph.D. in Biomedical Engineering from Florida State University and his BS in Chemical & Process Engineering from the University of the West Indies. Dr. Grayson holds a patent at EpiBone, one of the world’s most watched biotech startups. His research interests focus on 3-D-printing custom-designed scaffolds for facial bone tissue regeneration.

Grayson has been recognized by the Maryland Science Center as an Outstanding Young Engineer, and received awards from the Orthopaedic Research Society and the American Society for Bone and Mineral Research. Additionally, he has received the TERMIS Young Investigator Award, and the Early Faculty CAREER Award from the National Science Foundation. He has authored over 50 original and review articles and book chapters and holds several patents for bioreactor and biomaterial designs.

The Grayson Lab for Craniofacial & Orthopaedic Tissue Engineering addresses the challenges associated with spatio-temporal control of stem cell fate in order to engineer complex tissue constructs. Grayson and his research team are developing innovative methods to guide stem cell differentiation patterns and create patient-specific grafts with functional biological and mechanical characteristics. They employ engineering techniques to accurately control growth factor delivery to cells in biomaterial scaffolds as well as to design advanced bioreactors capable of maintaining cell viability in large tissue constructs. These technologies are used to enable precise control of the cellular microenvironment and uniquely address fundamental questions regarding the application of biophysical cues to regulate stem cell differentiation.
