Research Interests

My research interests are mostly graph theory, graph algorithms and network science. In particular, I am interested in reducing the gap between theory and practice, by gaining a better understanding of what makes some graph problems easy or hard in the real world, and how algorithms exploit such properties. We can use network models as proxies to understand this relation between properties and algorithm behavior.

As Advisor

Other Activities

I enjoy sharing my knowledge and enthusiasm for computer science with students. Therefore, I was active in the HPI's Youth Academy, developing and organizing camps and workshops for young students. I also support the BWINF (Bundeswettbewerb Informatik), and was a mentor for the Make Your School project.

In my freetime, I enjoy playing Volleyball, Beachvolleyball and Badminton, and swimming. I also play the piano and enjoy singing in the student a cappella group "Source Chord".
