Biography

William is a PhD student and text-adventure author. They are currently attending Johns Hopkins University (Piscataway land), studying in the Physics and Astronomy Department. They conduct research at the Space Telescope Science Institute in order to understand the growth, evolution , and composition of giant planets, brown dwarfs, and very low mass stars. They graduated from Amherst College (Nonotuck land) in May 2021 with a Bachelors of Arts in Astronomy and Physics, receiving a departmental recommendation for summa cum laude honors based on their thesis research. You can read an informal description of their research, peruse various blog posts, and view their astrophotography, over on their personal website.
