William is a PhD student, freelance science journalist, and author. They use the Very Large Telescope Interferometer (VLTI), the Hubble Space Telescope (HST), and the James Webb Space Telescope (JWST) to study planets in other solar systems. They are a Ph.D candidate in the Department of Physics and Astronomy at the Johns Hopkins University in Baltimore, MD (Piscataway land). They were NASA’s Maryland Space Grant Observatory Fellow for the 2022-2023 academic year. This static site hosts William’s CV and links to their peer-reviewed articles and presentations. You can read an informal description of their research, peruse various blog posts, and more on their personal website. Last updated 2023/08/20.
