I am a PhD student at Computer Science Institute of Charles University under the supervision of Robert Šámal. I received my Master's degree in Mathematics from Sharif University of Technology, where I was advised by Ebadollah S. Mahmoodian and Javad B. Ebrahimi. My research interests lie in Combinatorics, Graph Theory, and Combinatorial Optimization. As a researcher I specialize in tackling deep theoretical problems using a combination of mathematics, computer science, and data-driven approaches. Alongside research, I have hands-on experience in Python programming, data analysis, and SQL (PostgreSQL), and I’m expanding into data engineering and science. I’m passionate about translating complex problems into clear insights, and I enjoy roles that bridge theory and practical impact.

My hobbies

I play football, volleyball, bowling, billiards, tennis, badminton, and other sports whenever possible. Apart from playing sports, I like doing programming and watching movies and TV series.
