About me
I am a mathematician specializing in combinatorics and algorithms. The research topics I have studied are diverse, their nature hovering around the boundary of theoretical and applied mathematics. Extremal and graph theoretical themes are regularly featured in my papers.
To take a break from work, I enjoy riding around the hilly regions of the country. I also love cooking dishes of different cuisines. I find reading about antrohopology, philoshophy, physics, and economics inspiring. Sometimes I make enamel art on copper.

Accessible website about COVID
Providing scientifically accurate yet easy to understand up-to date information about COVID-19 from the early stages of the pandemic on. Responsible for website design and structure. Proofread most of the content.
It is cited in the recommendations for decision-makers by the Hungarian Academy of Sciences as a widely acclaimed website targeting laypeople with science-backed information.
The website was also featured by ELTE (my MSc and BSc alma mater).
Board member at my condominium
I served from 2018 until 2021 as the chair of the supervisory board of the building I live in. Since 2021, I am the deputy chairman of the board managing the condominium. Voluntary work.
