Expertise

Prefer questions regarding general chemistry, analytical chemistry, and physical chemistry. Have less knowledge about organic chemistry but can help with most undergraduate organic chemistry questions not related to reactions and their mechanisms.

Experience

Highly experienced in physical chemistry both theoretical and experimental. Current research focus is fluorescence spectroscopy and electronic structure theory (e.g. quantum mechanics). Past research focus was in analytical chemistry in the area of photocatalysis.
