Activities

I am active in the ACM, IEEE, GI (video), the ComTec Alumni and the Alumni Informatik Dortmund.

I am looking forwad to participate in the NII Shonan meeting on Intelligent Information Processing - Chances of Crowdsourcing.

I have attended the Dagstuhl seminar 12492 on Human Activity Recognition in December 2012. All pretty amazing for me.
There is a report available here.
