Precision Porous Biomaterials

We specialize in producing precision porous biomaterials for pro-healing, integrative scaffolds using microbead methods or 3D printing.

Surface Analysis & Modifications

Through surface modifications (e.g. low-fouling polymer brush grafts, RFGD fluoropolymer plasma deposition, etc.), we are pursuing fully biocompatible materials for a variety of applications including orthopedic devices, insulin delivery systems, and continuous dialysis machines.

Dialysis Innovation

In partnership with the Center for Dialysis Innovation (CDI), we are collaborating with Northwest Kidney Centers and several UW research labs to revolutionize dialysis treatment and care.

Neural Implants

Using precision porous materials combined with conductive hydrogels, we are developing immunomodulatory neural implants.

Kidney Regeneration

Using our porous templated scaffolds, we seek to enhance the vascularization and integration of kidney organoids.

The field of biomaterials has always embraced new ideas and developments, and that is still happening.

The seamless integration between synthetic materials and biology is where much of our research is heading. There are also so many new developments in electronics and sensors, and I can envisage a new class of biomaterials that seamlessly integrates with humans and gives us a monitoring and healing function, or a restorative function.
