Research Projects

Our immunity is one of the finest defense systems. What if we could engineer novel materials to unleash its potential across cellular, tissue, and system scale for medicine?

Nano-structures for non-viral immuno-engineering

Despite several decades of research, it is still challenging to transfect primary immune cells with high efficiency while maintaining high cell viability and functionalities. We are developing high-throughput, non-viral and minimally perturbative cargo delivery technique using nanotechnology.

Major publications:

Bioresorbable lymph node tissue-machine interfaces​

Lymph nodes are sites for critical immune activities like T cell activation and proliferation. However, due to aging and cancer, their micro-environments can no longer support healthy immune processes. We are developing  bioresorbable hydrogels and implants to sense and modulate lymph node micro-environments in vivo.

Immunogenic magnetic bacterial micro-robots​

Targeted drug delivery to solid tumors is an pillar of cancer therapeutics. Making use of microfluidic  systems, we are evolving magnetic bacterial micro-robots capable of precise delivery of biologics and drugs to solid tumor. They can also be used concurrently with magnetic hyperthermia to awake cancer-suppressed immune systems for synergistic therapies.
