Research on the Molecular Scale
Lab experiments on CO2-O2 photochemistry in support of atmospheric applications
Lab experiments and global modeling of isotopic fractionation during formaldehyde photolysis in support of predicting the effects of switching to a hydrogen fuel cell-based economy
Lab experiments on isotopic self-shielding at ALS to understand isotopic fractionation in earth and extraterrestrial materials (e.g., primitive and martian meteorites)
Reaction dynamics experiments on oxygen isotope exchange reactions important in the atmosphere and to projects noted above (e.g., CO2+O(1D), NO2+O, O2+O)
Lab experiments on the 'bizarre' isotope effect in the production of ozone Can an efficient 3rd body collider overcome the so-called quantum 'symmetry' isotope effect?
Photochemical production of hydrocarbon aerosols What is the underlying kinetics of hydrocarbon aerosol formation in planetary atmospheres and what are the optical properties of these particles?

Research on the Global Scale
CH4 isotopic compositions and modeling Refining the global isotope budget through additional measurements and 3D modeling (e.g., needed for Kyoto Protocol)
N2O isotopic compositions and analysis Refining the global isotope budget through additional measurements in the stratosphere, troposphere, Amazon Forest, temperate agricultural sites, and controlled laboratory experiments on microorganisms
Isotopic measurements for NASA field campaigns (WB-57F aircraft and high altitude balloons): To aid in 'validating' AURA satellite measurements and to resolve outstanding chemistry and transport issues in the upper troposphere and lower stratosphere, such as water vapor transport and its trends and ozone depletion and the recovery of the ozone layer in the context of global change
CO2 isotopic compositions, analysis, and modeling New stratospheric and upper tropospheric measurements and their global scale modeling (2D) and their application as a new tracer of ozone depletion to understand why models are still not 'hindcasting' properly the ozone trends observed (Aura Mission)
