I am a postdoc in the theory of computation group at MIT working with Erik Demaine. I obtained my PhD in computer science from Humboldt-Universität zu Berlin in August 2010, supervised by Martin Grohe.

My main research interests are:

• Algorithmic graph structure theory, esp. planar graphs, graphs on surfaces, and graph minors
• Graph algorithms, esp. network design and approximation schemes
• Parameterized complexity theory, esp. in connection with logic
• Algorithmic game theory
• Implementation and engineering of theoretical algorithms

I have also been continuosly involved in teaching ever since my first undergraduate year.

I am co-teaching 6.889 Algorithms for Planar Graphs and Beyond at MIT this term!

The lectures are being video taped and are available online.

In particular, I have given the following lectures: L05, L06, L07, L09, L10, L16, L17, L22, L24.
