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

We are actively recruiting enthusiastic scientists and engineers to join our team!

 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.
