Since April 2010 I am with the chair for Pervasive Computing at the KIT under the supervision of Prof. Dr.-Ing Michael Beigl. My research interests include the design, analysis and optimisation of algorithms for context prediction, distributed and ubiquitous systems and collaborative transmission in Wireless sensor networks.
Currently, I am engaged with the National Institute of Informatics (NII) in Tokyo, Japan in the group of Prof. Yusheng Ji.

Thesis and student work

Are you interested in the research branch and are considering writing a thesis at our institute?
In these cases please contact me via Email. We constantly discuss intriguing research questions but do not formulate all of these right away as thesis proposal. Also, if you have your own research idea I would much like to discuss it with you.
