PhD student

Supervisor: Mészáros Szabolcs, (2026)

Biography:

As a member of the MTA-ELTE Momentum Milky Way Research Group, my research focuses on the comparison between high-resolution spectroscopic sky surveys and modelling the galactic chemical evolution of the Milky Way traced by the observed SDSS (APOGEE and Milky Way Mapper) stellar atmospheric abundances.

I got my BSc degree at The University of Szeged in 2020. My bachelor thesis investigated the gravitational magnetoelectric effect in special spacetimes. I participated and granted a special prize on the OTDK with this study. For this project, I have earned the prestigious scholarship of the ÚNKP New National Excellence Program.
I earned my MSc diploma in astrophysics also at the University of Szeged in 2022. In my MSc diploma thesis I have presented a comparative analysis of radial velocities and atmospheric parameters from high-resolution spectroscopic sky surveys: APOGEE, GALAH, Gaia-ESO.
In my PhD thesis, I model the galactic chemical evolution with semi-analytical code OMEGA+, based on stellar data published in the fifth phase of SDSS. Since 2023, I have been supported by the DKOP-23 Doctoral Excellence Program of the Ministry for Culture and Innovation from the Source of the National Research, Development and Innovation Fund.
