I am currently pursuing a PhD at EPFL in Computer Science.
My advisor is Ola Svensson and so I am part of the Theory group.

My main research interests include online and approximation algorithms.

Before moving to Switzerland, I obtained both my Bachelor's and Master's
in Computer Science at TUM in Germany.
