About me

I am PhD graduate in mathematics at the University Paris-Saclay in France and University of Vienna in Austria. My advisors were Alin Bostan and Herwig Hauser and my interests are integer sequences, differential operators and algebraic power series. I also have a master's degree in mathematics and another one in quantitative finance.
