The primary goal of our research is to understand fundamental nanomaterial interaction with radiative and molecular environments, and to use the observed phenomena for various applications including renewable energy and bioengineering. Our ideas for technological breakthroughs are often inspired by biological processes in nature. Our effort includes design and fabrication of nanoparticles with molecular recognition domain, using nanocrystals, carbon nanotubes, graphene, and various biomaterials. The novel properties of these nanomaterials are exploited to study nanoscale energy conversion and transport processes, and to develop novel devices with new levels of system control at the nanoscale. Characterization techniques include absorption, Raman, and photoluminescence spectroscopy ranging from UV to near-infrared, with an emphasis on single nanoparticle imaging and spectroscopy. Additionally, atomic force microscopy and spectro-electrochemistry are methods commonly used in the lab. While we focus on fundamental nanoscience and nanoengineering, we aim to make transformative impacts in our society as well as scientific community. Our current projects include:

                                                  Nanoscale Energy Conversion

                                                  Optical Nanosensor Architecture

                                                  Bioinspired Nanomechanical Systems

                                                  Biomolecular Nanomanufacturing
