I am a scientist with a wide range of interests in trying to understand how our world works. I have a particular interest in studying the solid/gas, solid/liquid, and solid/solid interfaces of energy storage and conversion materials such as fuel cells, electrolyzers, catalysts, and batteries using Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS).
