Since January 2014 to present, I'm a Ph.D. student in the Computer Science Department at Saarland University, under the supervision of Prof. Kurt Mehlhorn. I am also affiliated with the Algorithms and Complexity Department at Max Planck Institute for Informatics and the Cluster of Excellence on "Multimodal Computing and Interaction".
