Yijin conducts research in materials science at multiple length scales using synchrotron techniques. He is particularly interested in materials under extreme conditions (e.g. high pressure and temperature) and energy materials including batteries and photovoltaic thin films, as well as the applications in geo-science such as study of underground formations for CO2 sequestration and unconventional oil production.

Piero is interested in ultrasensitive methods for analyzing contamination on silicon wafer surfaces and understanding the relationship between the atomic and electronic structure of semiconductor interfaces and their electrical properties. See Piero's Homepage.
Joy C. Andrews
Joy's research is on energy materials including batteries, fuel cell and catalysts. Correlation of nanostructure (including porosity) and chemical states ex situ, in situ and in operando, using techniques including full-field hard X-ray transmission microscopy, X-ray absorption spectroscopy (XAS), and scanning X-ray fluorescence.
