Boston College, Ph.D. in Chemistry
Warren de Bruyn obtained his Ph.D. in Physical Chemistry from Boston College in 1994. He held post-doctoral and research faculty positions at the University of Miami and UCI before coming to Chapman in 2002. He is a physical/analytical chemist with primary research interests in atmospheric chemistry. Current research is focused on the oceanic cycling of sulfur species and oxygenated hydrocarbons into or out of the troposphere which have implications for global climate change and the oxidative capacity of the troposphere. This work involves instrument development, laboratory kinetic measurements, coastal field measurements and open ocean measurements. He is committed to undergraduate student research and usually has 3-4 Chemistry majors working in his lab. Since 2007 he has had 4 major proposals funded (three from NSF and 1 from ACS). During that time he has also published 15 journal articles, 9 with undergraduate student co-authors.
