Regenerative Engineering

Dr. Laurencin has pioneered a new field, Regenerative Engineering, described as the Convergence of areas such as nano-materials science. He recently received the Founders Award from the National Academy of Engineering in large part for his work in this field. His work has uncovered signaling molecules for tissue regeneration and he has created a new class of stem cells: synthetic artificial stem cells (SASC), published in the Proceedings of the National Academy of Sciences.
