Hi! I'm a 2nd-year PhD Student at University College London.
My research focuses on the interpretation of exoplanetary atmospheres using Bayesian retrievals and atmospheric models supported by observations from the James Webb Space Telescope. I am most interested in studying the atmospheres of super-Earths and sub-Neptunes in the habitable zones of late-type stars. Check out my latest work below! ★
Aside from exoplanet research, I also own a small art business and I’m a massive Pokémon fan!
