An expert in microfluidic lab-on-a-chip technologies, Han joined the faculty in August 2005. He received his bachelor's degree from the Seoul Na­tional University in Ko­rea in 1997 and his master's degree from the University of Cincinnati in 2000. In August 2005, he received his Ph.D. degree in electrical engineering from the Georgia Institute of Technology. Han's research interests lie in the devel­opment of microfluidic and lab-on-a-chip systems for applications in cellular and molecular analysis. Particular focus areas are in developing high-throughput screening systems and portable detection systems for applications in developmental neurobiology, cancer metastasis, infectious diseases and microbe-mediated bioenergy solutions.
