After joining FSU in 1970 and serving six years as department head, I developed an academic program of teaching and research. My research emphasized atmospheric and environmental chemistry. My teaching emphasized linking different disciplines to understanding global environmental change and its human dimensions.

In cooperation with the Van de Graaff accelerator laboratory of the Dept. of Physics, we developed proton induced X-ray emission (PIXIE) and used it for trace element analysis of atmospheric aerosol samples. Field studies were carried out in Florida and in remote regions to infer transport and transformation processes and impacts of natural and pollution sources on air quality. Participants included graduate students who completed nine Ph.D. dissertations and 13 M.S. theses as well as 27 post-doctoral and other visiting scientists.

Since becoming Professor Emeritus in 2003, I now work informally with faculty and students of environmental chemistry, especially to improve public understanding of science and to advance policies for a sustainable future.
