Welcome! 

I am a theoretical astrophysicist interested in binary stellar evolution and high-energy astrophysical phenomena. My research focuses on modeling mass transfer between stars in binary systems and on relativistic eruptions from highly magnetized neutron stars, known as magnetar giant flares. 

In September 2025, I defended my PhD thesis “Theory of stellar mass loss: from binary stars to magnetars” under the supervision of Ondřej Pejcha at Charles University in Prague. In October 2025, I joined the Astronomical Institute of the Slovak Academy of Sciences in the Tatra Mountains as a research scientist, and in November 2025, I will begin a postdoctoral fellowship at Tartu Observatory, University of Tartu, Estonia, under the guidance of Indrek Vurm.

Before moving into astrophysics, I worked in the field of continuum mechanics under the supervision of Vít Průša.
