It is our great honor to have Dr. Kevin Chung from the University of Michigan (UM) visiting us again as our Distinguished Professor last week. He gave us a grand round of hand surgery for Plastic Surgery and Orthopedics, and a series of research master classes. Appreciate the time, experience and knowledge you shared with us. We have learned so much and made incredible progress through the commitment, interaction, leadership, and trust from the collaboration between UM and CGMH. I cannot thank Dr. Chung enough for his tremendous support for Chang Gung.
