I am an astronomer at NASA's Ames Research Center in California. I primarily study the atmospheres of extrasolar giant planets, brown dwarfs, and solar system giant planets. (Note that the opinions I express are my own and not those of NASA.)
I have served on multiple committees that offer advice to NASA on topics ranging from the best strategies to study extrasolar planets, to exoplanet-detecting telescope design, to the optimal outer solar system exploration strategy. I currently serve on the "Science and Technology Definition Team" for the proposed "Exo-C" space-based coronagraph telescope.
On Google+ my public posts tend to be articles or items that have caught my eye, mostly regarding extrasolar planets and brown dwarfs. I don't aim to provide a content stream.
