Richard is a professor at Lamont-Doherty Earth Observatory.
He studies climate variability and change on timescales of seasons to millennia and in particular the causes of multiyear droughts around the world and how climate change will impact global hydroclimate. He uses numerical models, observations, and proxy reconstructions of past climates to understand the physical mechanisms responsible for climate variability and change on seasonal to glacial-interglacial timescales.
Recent work has focused on the mechanisms of persistent North American drought and its relation to tropical Pacific and tropical Atlantic Ocean temperature variations.
