Qiuming Yu received her B.S. and M.S. in Chemistry from Nanjing University, China in 1985 and 1989, respectively, and her Ph.D. in Chemical Engineering from Cornell University in 1995. She was a postdoctoral fellow in the Micro-devices Laboratory at the NASA Jet Propulsion Laboratory, California Institute of Technology, from 1995-1996. After spending three years as a research assistant professor in Chemical Engineering at Kansas State University, she moved to the University of Washington and was a full professor in the Department of Chemical Engineering. She joined the Robert Frederick Smith School of Chemical and Biomolecular Engineering at Cornell University in July 2020 as a professor.
Professor Yu's research focuses on the fundamental studies of plasmonic and semiconductor materials and the development of devices for biosensing and optoelectronic applications with an integrated computational and experimental approach. For biosensing, her research group is primarily using optical signals, specifically, surface plasmon resonance and surface-enhanced Raman scattering, as the transducing mechanism. They have designed plasmonic nanostructures and developed surface chemistries to enable specific, sensitive and accurate detections of small molecules, proteins and microorganisms for a broad application ranging from biomedical diagnosis, food safety, environmental monitoring, to homeland security. Her research group is recently interested in the development of biocompatible conducting polymers for bioelectronics and organic electrochemical transistors with the goal for wearable and remote sensing. For optoelectronic materials and devices, her research lab focuses on the studies of structural and optoelectronic properties of halide perovskites, organic semiconductors, and nanocomposites, as well as fundamental physics of charge generation, separation, and transport in devices. They are developing new hole and electron transport materials to facilitate charge transport and collection. Her lab is also interested in the integration of plasmonic nanostructures into photovoltaic devices and photodetectors to utilize hot electrons, and to manipulate light absorption and electric field distribution. Her group aims to develop light and mechanical flexible photovoltaic devices and spectral-selective photodetectors for energy harvesting and light sensing. Research Group Members
