Dr. Xiao-Ying Yu

Xiao-Ying Yu

Distinguished Scientist and Group Lead, Advanced Nuclear Materials

Dr. Yu is a distinguished scientist at the Oak Ridge National Laboratory (ORNL). She was trained as a physical chemist and kineticist at the University of Michigan, Ann Arbor, MI.  She did her postdoctoral research at Brookhaven National Laboratory.  She became a staff scientist in the Department of Atmospheric Sciences at the Colorado State University, Fort Collins, CO. Prior to joining ORNL, Dr Yu had worked as senior staff scientist and chief engineer at the Pacific Northwest National Laboratory for over 16 years.

Dr. Yu’s research has evolved to understand interfacial phenomena at the fundamental atomic and molecular level that are relevant to the observed changes across multiple time and space scales in the environment, with implications in biological systems (e.g., biofilm, cell), aerosol, catalysis, and materials in operating conditions.  She has led the development of novel molecular imaging capabilities based on microfluidics, which has resulted in multiple patents, a prestigious R&D 100 award in 2014 and the Federal Laboratory Consortium Technology Transfer award in 2015.  Direct in situ and operando observations of complex liquid surfaces and liquid and solid interfaces were enabled by her unique chemical imaging techniques.  She has developed new concepts in aerosol sampling besides her efforts in multimodal chemical imaging.  Dr. Yu has led and participated in many field studies for in situ measurements of aerosols and determination of their chemical compositions and physical characteristics.  In addition, Dr. Yu has been an active member of the DOE NA41 chemical exposure working group; and has led the development of the chemical mixture methodology and supported the Protective Action Criteria for consequence assessment of toxic health effects since 2007.
