I am a JSMF postdoctoral fellow in MIT’s Department of Earth, Atmospheric and Planetary Sciences.

I did my undergraduate work at Harvard, where I studied Physics and Philosophy. I received my PhD from UChicago’s Department of Geophysical Sciences, where I worked on the atmospheres of extrasolar planets and past climates of Earth.

December 2019

Our three papers on how to quickly search rocky exoplanets for atmospheres are now out in ApJ (here, here, and here). You can read more about our results in this NASA press release and at Sky & Telescope.


September 2019

Our new paper on the rocky exoplanet LHS 3844b (led by Laura Kreidberg) is now out in Nature, and another paper on rocky planets with hydrogen atmospheres (led by myself) is out in ApJ.


April 2019

Kudos to Henri Drake, who made a neat visualization of CO2’s greenhouse effect using PyRADS.

Find out what Henri did here.


July 2019

Enough of seeing red? The shortwave version of PyRADS is now on github.


September 2018

I’ve recently developed PyRADS, a line-by-line radiation code appropriate for research in planetary atmospheres and for teaching radiative transfer, which runs (almost) entirely in Python! To download the code, go to my github.
