RESEARCH SUMMARY A fusion of biology with the physical and engineering sciences is vital for future advances in biological and biomedical research. The development of novel instrumentation is a key ingredient towards advancing scientific research. I am particularly interested in technology development which exploits novel phenomena accessible at micro- and nano-scales. Currently, I am developing microfluidic devices for high throughput and sensitive bioanalysis to accelerate cost-effective generation of lignocellulosic biofuels. This work is being performed in collaboration with the Joint BioEnergy Institute (JBEI), Emeryville. I am also interested in development of integrated systems for clinical, genomic, and proteomic applications. Some examples of my past work include development of microfluidic liver cancer clinical diagnostic system, integrated sample prep and RT-PCR device for RNA/DNA analyses, and high-sensitivity label-free protein separations. My doctoral work focused on investigation of nonlinear electrokinetic (EK) phenomena pertaining to sample pre-concentration techniques. I remain interested in fundamental and applied aspects of in-vitro and in-vivo EK processes.
