Joshua Tam is an Instructor in Dermatology at the Wellman Center for Photomedicine, Massachusetts General Hospital. He received his PhD in Biomedical Engineering from the Harvard-MIT division of Health Sciences and Technology, then joined Rox Anderson’s lab at the Wellman Center as a post-doctoral fellow, where he was the lead scientist in developing a new technology to harvest autologous, full-thickness skin in the form of “microcolumns”. These microcolumns can be directly applied into wound beds to accelerate wound healing, similar to conventional autologous minced skin grafts, but with the key advantage that each donor wound is small enough to close spontaneously within days, and without any long-term donor site morbidity or scarring. He was awarded the 2016 Wound Healing Foundation 3M Fellowship for his work. This technology has led to an FDA-cleared device that is now in clinical use.
