Areas of Specialization
My research work has been on long range transport at large scales, in collaboration with atmospheric chemists, volcanologists, and paleoclimatologists. We use ozonesondes to obtain vertical profiles above Narragansett to study the role of meteorological processes in atmospheric chemistry; and we observe near-surface winds to study the extent and variability of trends.
I advise graduate students, teach a graduate course on climate, OCG 535, and co-instruct an undergraduate oceanography course, OCG 123.
