Greetings Lamont Alumni!

I am the new President of the Lamont-Doherty Earth Observatory Alumni Association Board Having studied with Peter deMenocal, Jean Lynch-Stieglitz, and several other wonderful folks, I finished my paleoclimatology PhD in the Department of Earth & Environmental Sciences in 2005. Since then, I have been teaching at Hofstra University on Long Island. I’m honored to follow in Greg Mountain’s footsteps as President and to carry on the Board’s mission to advocate for the welfare of the Observatory.

By any standard, Celine Herweijer’s rise in the world of climate policy has been meteoric. Born in London, Herweijer came to New York to pursue graduate studies at Columbia, where she wrote her PhD thesis on drought modeling with Lamont-Doherty modelers Mark Cane and Richard Seager.
