Research Interests

I am interested in Network Analysis and Distributed Computing. While I like analyzing big data with the help of networks, I am focused on more local questions with respect to distributed graph algorithms. I particularly like to investigate networks formed in the real world exhibiting social phenomena. Summarized to one sentence: I like graphs and investigating their properties.

I like all sorts of puzzles that are easy to state and not (necessarily) so easy to solve. I am always up for new topics and ideas.
