Research Interests

Research in the Williams Immune Nanomedicine Lab is focused on using nanomaterials to target and understand immune and inflammatory pathways in disease. Specifically, we design kidney-targeted polymeric nanoparticles as therapeutic tools for renal diseases. We also design implantable optical nanosensor devices as diagnostic tools for cancers and related diseases. We aim to translate these tools to the clinic and to use them to understand biological processes in disease.
