Areas of Specialization
Research
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 in satellite validation efforts.Teaching
I advise graduate students, teach a graduate course on climate, OCG 535, and an undergraduate oceanography course, OCG 123.Outreach
I collaborate with a group at Medgar Evers College, CUNY, Brooklyn led by Prof. Shermane Austin, assisting in advancing their student-oriented balloon profiling program to include ozonesondes.Students
