Research Interests:

• Nanocrystal synthesis, including mechanistic understanding, experimental control, and methodology development
• Nanomedicine, including targeted delivery and controlled release, molecular imaging for early cancer diagnosis, and effective treatment of cancer and other diseases
• Regenerative medicine, including bio-inspired design of novel scaffolds with well-controlled properties for manipulating stem cell differentiation, neurite outgrowth, tissue regeneration, and vascularization in a large tissue construct
• Structure-property relationship of shape-controlled nanocrystals, including localized surface plasmon resonance (LSPR), surface-enhanced Raman scattering (SERS), light harvesting, local field enhancement, plasmonic waveguiding, and metamaterials
• Catalysis, including surface capping, facet-dependent catalytic activity and selectivity, sinter resistance, as well as more active and robust catalysts for proton-exchange membrane fuel cells
