In early June, I was honored to give a keynote address at the World Biomaterials Congress in Chengdu, China. During my talk, “Hierarchical Nanostructures for Tissue Regeneration,” I highlighted the elegant work done by the Institute for Regenerative Engineering, including my students and fellows. The symposium, Hierarchical 3-Dimensional Structures for Tissue Regeneration, was chaired by my former graduate student, Professor Justin Brown from the Department of Bioengineering, Pennsylvania State University. In addition, Dr. Lakshmi Nair, Dr. Sangamesh Kumbar and Dr. Meng Deng, also from the Institute, gave talks during the symposium. This was my first visit to Chengdu, I was deeply impressed by its natural beauty, as well as its historical and culture treasures. I so appreciated the hospitality provided by the planners. I also want to thank Professor Xingdong Zhang, chairman of the 9th WBC organizing committee, for arranging a wonderful conference.
