Research"Everything flows and nothing abides, ~Heraclitus~ In keeping with Heraclitus, the Earth's climate changes too. In fact, it is currently changing in ways that we urgently need to understand if our society is to successfully adapt to them. Climate dynamics is the field that studies the processes that control climate and how it changes over time. Such changes can be of natural or human origin, and this group's focus is to tease out the two. Since climate is determined by the interaction of the atmosphere, the oceans, the land surfaces, the cryosphere and the biosphere, it naturally straddles disciplinary boundaries between physics, chemistry, mathematics, biology, geology and computer science. This makes the field as unfathomably complex as it is fascinating, and provides research opportunities for virtually any science student who's up for a good puzzle (and possibly a few headaches). Broadly speaking, my research is concerned with the role of the Tropics in long term climate variability. The central actor of this game is of course the El Niño-Southern Oscillation (ENSO) phenomenon, whose behavior I strive to understand on decadal to millennial timescales. My group's current research interests include :
