Research Experience
-
2025 - 2027 Multi-modal self-supervised learning on JWST data
Max Planck Institute for Astronomy, Heidelberg Master's thesis project · Advisors: Dr. Ivelina Momcheva, Dr. Morgan Fouesneau - Trained an in-house foundation model on sparse, multi-survey JWST data — NIRISS/NIRCam imaging and low-resolution PRISM spectra — fused via CLIP.
- Enables population-level inference of galaxy properties (e.g. stellar mass) from single-band photometry and spectroscopy.
-
2024 - 2025 Spatially resolved Balmer decrements of individual galaxies
Max Planck Institute for Astronomy, Heidelberg Bachelor thesis · Advisors: Dr. Ivelina Momcheva, Prof. Dr. Hans-Walter Rix - Analysed HST/CLEAR and JWST OutThere pure-parallel grism spectroscopy.
- Developed a PSF-matching technique for grism emission-line maps.
- Produced the first reff-normalized Balmer decrement profiles at z > 1.
- Constrained the galaxy-to-galaxy scatter in resolved dust attenuation and its relation to stellar mass and resolved star formation.
-
2023 Trapping and cooling Rb atoms with a self-built MOT
Kirchhoff Institute for Physics, Heidelberg University Curriculum extension · Advisor: Prof. Dr. Klaus Reygers - Built a 3D magneto-optical trap (MOT) from scratch in a student team, cooling and trapping rubidium atoms close to the Doppler limit.
- Aligned and fine-tuned the optical setup for the cooling laser beams.
-
2022 Optical observations with a 70-cm telescope and data reduction
State Observatory Heidelberg-Königstuhl Independent project · Advisor: Prof. Dr. Jochen Heidt - Operated the 70-cm telescope.
- Implemented a data-reduction pipeline for raw stellar images and performed photometry.
Conferences and Workshops
-
