Jianyu received his B.S. in Polymer Science and Engineering from Zhejiang University, China in 2010, and a Ph.D. in Engineering Sciences from Harvard University in 2015. His thesis work involved developing novel biomaterials with unprecedented mechanical properties, in particular, stiff and tough hydrogels for cartilage replacement. He joined the Programmable Nanomaterials Focus Area as a post-doctoral fellow in 2015, where he worked on developing hydrogel drug delivery systems for tissue regeneration. As a Wyss Technology Development Fellow, he will continue to work on controlled drug delivery using hydrogels, and develop novel tissue-adhesive tough hydrogels for broad biomedical applications such as wound dressings, tissue adhesives and myocardial patches.
