Personal profile

Research interests

I am interested in developing and understanding the properties of nano/bio-materials and engineering the surface chemistry for various biomedical applications. The primary focus is on engineering polymeric and or metallic/metal oxide nanoparticles, and composites for cancer targeting, drug/molecular delivery, tissue engineering, bone regeneration and dental applications.
