As a principal researcher at DFKI, I have been doing the following things since 2001:

  • Conducting research on general issues in the area of interactive intelligent systems and human-computer interaction
  • Directing more application-oriented research projects in in these areas
  • Conducting targeted research in these areas for industrial clients (this work is not represented on this website)
  • Giving talks and courses to convey the general lessons learned from this research and practice


[Chusable logo] At the end of 2016, I founded the DFKI spin-off company Chusable AG, which is based partly on technology developed within the EIT Digital innovation activity 3cixty. I am currently spending most of my time developing the first two Chusable products, though I still contribute part-time to some DFKI activities.
[Persuasive 2017 Logo] At Persuasive Technology 2017 in Amsterdam, I held a half-day tutorial on April 4th to explain how people in the persuasive technology field can benefit from an understanding of the psychology of choice and choice support. The slides and other detailed information are available from the page about the tutorial.
