Dr. Xiao-Ying Yu is a distinguished scientist at the Oak Ridge National Laboratory. She obtained her doctoral training in physical chemistry at the University of Michigan, Ann Arbor. Dr. Yu has led the development of a novel molecular imaging tool based on microfluidics that enables multimodal imaging since 2007. This new technology has resulted in multiple publications, several patents, the prestigious R&D 100 award in 2014, and the FLC technology transfer award in 2015. Her research expertise spans from aerosol collection and characterization and toxicity exposure assessment to fundamental kinetic studies. Her research effort focuses on chemical imaging of surfaces and interfaces of importance in biology, catalysis, material synthesis, and energy storage involving the liquid condensed phase using innovative approaches. Most recently, Dr. Yu started to apply mass spectral imaging in materials research and development suitable for extreme conditions.
