OUR mission

Our mission is to create new biomaterials that can precisely deliver therapeutic proteins that can support regeneration across injuries and tissues. 

Our lab combine expertise in chemical and biomedical engineering to design new biomaterials and harness natural affinity interactions to precisely deliver proteins to injured tissues to support regeneration. 

Research

Our lab uses a variety of approaches, including directed evolution for protein delivery, cell-instructive biomaterials for bone repair and predictive bio-transport modeling.
