I am a fifth-year graduate student in the Department of Astronomy and Astrophysics at the University of California, Santa Cruz. I work with Natalie Batalha to detect and precisely characterize exoplanets.
I am an experienced Keck-HIRES observer and a member of the TESS-Keck Survey (see Chontos+ 2022 for a survey overview).
As an undergraduate and master's student at Stanford University, I worked with Bruce Macintosh and Ian Czekala on disentangling the spectra of T Tauri stars using Gaussian processes.
In my free time I love to run, cycle, surf, and swim.

In my latest first-author paper, we report mass measurements for 12 planets across eight TESS systems. We use an end-to-end joint photometry, radial velocity, and stellar activity modeling framework to homogeneously derive planet parameters. Our code is publicly available online.
