Hettiaratchi Lab

Biomaterials for Protein Delivery and Tissue Engineering

Harnessing natural affinity interactions for precise protein delivery

Welcome to the Hettiaratchi Lab

We are a bioengineering research group at the University of Oregon’s Knight Campus for Accelerating Scientific Impact.

We welcome new lab members from all backgrounds and recruit through a variety of science and engineering graduate and undergraduate programs at the University of Oregon.

Our Approach

We combine expertise in chemical and biomedical engineering to design biomaterials to control protein delivery to injured tissues.

Directed Evolution for Protein Delivery

Cell-Instructive Biomaterials for Bone Repair

Predictive Bio-transport Modeling

Funding Sources

We are grateful for funding from the Collins Medical Trust, OHSU Medical Research Foundation, Department of Defense, National Institutes of Health, and Wu Tsai Human Performance Alliance.
