Ru-Shan is a research physicist in NOAA's Earth System Research Laboratory in Boulder. Colorado, USA. His principal research interests are 1. The measurement of trace gases and aerosols in the troposphere and lower stratosphere using instruments on board research aircraft, and 2. Interpretive studies addressing stratospheric ozone depletion, the photochemistry of nitrogen oxides, the formation of nitric acid containing aerosols, and the role of black carbon aerosol in climate. Ru-Shan has participated and served as Principal Investigator for a variety of instruments on a number of airborne sampling missions with research aircraft. Ru-Shan is considered by his colleagues to be a Master Craftsman who is outstanding at creating one-of-a-kind scientific devices for laboratory and field instruments.
