• I LOVE IT HERE.

    I'm a climate scientist, which means I get to study my favorite planet: Earth.

     

    I'm also a writer, storyteller, and human. And I'm so glad you've stopped by.

    Science and stuff

    Columbia University and NASA GISS

    Associate Research Scientist

    I study climate forcings (things that affect the planet's energy balance) and feedbacks (processes that speed up or slow down warming). Our work here has shown that observational estimates of the Earth's sensitivity to greenhouse gases are probably biased low: assuming climate changes will be small is not a very good idea.

    Lawrence Livermore National Laboratory

    Postdoctoral Researcher

    My postdoctoral work identified a "fingerprint" of human influence on global precipitation patterns and showed that we are already changing rain and snowfall. This is both reassuring, because it suggests climate model projections are credible, and terrifying, because it suggests climate model projections are credible.

    Carnegie Institution

    Postdoctoral Scholar

    How much wind power could we theoretically extract from the atmosphere before severe climate consequences result? Our work showed that this geophysical limit is large- an order of magnitude greater than worldwide electricity demand. So go ahead and put those turbines in the jet stream!

     

    Stanford

    Science Fellow

    As a Science Fellow at Stanford, I worked on policy-relevant scientific issues like nuclear power safety, climate model downscaling, and electrical grid resilience. Our work suggested that distributed grids, with electricity generated at local scales, can be inherently more fault-tolerant than centralized grids.
