His current research focuses on understanding surface/interface properties of microscale and nanoscale colloidal particles to achieve tailored optical, electronic, magnetic, catalytic, and structural properties, and exploring their biomedical and environmental applications. He is particularly interested in new chemistry towards nanostructures with structurally integrated inorganic nanocrystals and polymers and new approaches towards well-defined multifunctional assemblies of nanoscale building blocks. The key research topics in his lab include: Plasmonics and Surface-Enhanced Optical Properties; Interfacial Assembly of Colloidal Particles; In Vitro Diagnostics; Detection and Treatment of Antimicrobial Resistance; Controlled Delivery of Biologics.
