Hi, welcome to my webpage! I’m a theoretical astrophysicist specializing in planetary science and exoplanet research. I am currently a Postdoctoral Scholar Employee at the University of California, Los Angeles. Before that, I was a postdoc at Princeton University and am a member of the Center for Matter at Atomic Pressures (CMAP) collaboration.
I study how planets form and evolve over billions of years, and how observations can reveal information about their interior structures. I am the lead developer of APPLE — A Python Code for Planetary Evolution — a next-generation planetary evolution code for modeling the internal structures and thermal evolution of giant planets and exoplanets. (The code is currently private on my GitHub repository.) You can learn more about this work on my research page.
My earlier research focused on neutron stars and gravitational-wave astrophysics, including using gravitational-wave observations for cosmology. I earned my Ph.D. from the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences (Warsaw, Poland) in September 2022 and was a Predoctoral Fellow at the Center for Computational Astrophysics, Flatiron Institute (Simons Foundation, New York) from 2021–2022.
My CV can be found here, and my publications are here.

Aug 2026: I am invited to the Caltech campus to attend the Origin of the Uranian System. It is a closed-group meeting to refine the objectives and measurements required to probe Uranus's interior and constrain its origin from a spacecraft mission.
July 2026: I am a core member of the White paper "Layers of Understanding: Model Intercomparisons of Exoplanet Interiors," ---in preparation for the future ARIEL and PLATO Missions.
July 2026: Along with Rafael Fuentes, David Stevenson, and Peter Bodenheimer, we submitted a paper to ApJL showing how much mass double-diffusive convection can erode from the cores of Jupiter and Saturn.
