I am an atmospheric scientist particularly concerned with biogeochemical connections with the environment and global pollution. For me, this study is part of a broader understanding of the basic geophysics of living planets in the universe.

I 've been working at NASA's Ames Research Center since 1989. My research has also taken me so far to Washington State University, Colorado State University, the Max Planck Institute for Chemistry in Mainz, and the National Center for Atmospheric Research.

My interests have always centered on emissions from natural sources which strongly affect our admittedly human-perturbed atmosphere, the tropical/subtropical atmosphere, and the way that natural and pollution emissions make their way into the global atmosphere. There they can travel intact for amazing distances!
