Research

Research Interests:

• Photovoltaics
• Optoelectronics
• Micro-/nanophotonics
• Flexible electronics

Current Research:

My current research is centered in the general areas of solid-state electronics and photonics with particular attention to apply nanomaterials and micro-/nanofabrication for next-generation electronic, photonic, and optoelectronic devices. The research projects include design, fabrication, and characterization of colloidal quantum dot (CQD) and cellulose nanocrystal (CNC) based electronic and photonic devices, as well as micro-/nanostructured devices for sensing and energy harvesting.
