Dr. Subhadip Ghatak, is a core resident faculty member of the McGowan Institute for Regenerative Medicine and an Associate Professor of Surgery at the School of Medicine, University of Pittsburgh. He has additional faculty appointments in Bioengineering and Cellular and Molecular Pathology. He is recognized for his contributions to regenerative medicine, particularly in the areas of cellular crosstalk in tissue repair and regeneration. His laboratory integrates extracellular vesicle biology, nanotechnology, and gene reprogramming to unravel mechanisms of chronic non-healing diabetic wounds.
Dr. Ghatak has advanced the fundamental understanding of exosome-mediated cell-cell communication, microRNA regulation, and biofilm-driven wound chronicity. He has spearheaded federally funded research programs that have advanced the field of exosome biology, establishing how extracellular vesicles mediate cell–cell communication in wound healing and chronic disease. His group has uncovered mechanisms by which keratinocyte- and macrophage-derived exosomes regulate tissue repair and has developed innovative strategies to harness these vesicles as biomarkers and therapeutics.
Dr. Ghatak’s leadership extends across the extracellular vesicle field: he serves on the EV-TRACK task force, the NIH EV Interest Group, and several international EV societies, and is on editorial boards including Antioxidants & Redox Signaling and Frontiers in Medicine. He has received numerous awards, including the Wound Healing Society’s Young Investigator Award, multiple Excellence in Translational and Regenerative Science Awards, and the Mid-Career Faculty Award. In 2025, he was elected Fellow of the Royal Society of Biology and Associate Fellow of the Wound Healing Society.
