Hettiaratchi Lab

Biomaterials for Protein Delivery and Tissue Engineering

Harnessing natural affinity interactions for precise protein delivery

Welcome to the Hettiaratchi Lab

The Hettiaratchi Lab is a new bioengineering research group in the University of Oregon’s Knight Campus for Accelerating Scientific Impact.

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

Please see our posting for a Research Assistant (Technician).

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
