Klaus-Peter Engelbrecht is working as a Postdoc at the Quality and Usability Lab of Telekom Innovation Laboratories, TU Berlin. He studied Communication Research and Musicology and received his Magister degree in 2006 from TU Berlin. In July 2011 he successfully defended his Dissertation thesis entitled "Estimating Spoken Dialog System Quality with User Models". His current work deals with modeling how users experience interactions with automated dialog partners, and how this impacts the judgments they provide about them. From 2013 to 2014, he managed the BMBF Forschungscampus project "Interaktion & Sensoren", which dealt with innovative ways of interacting with technology in the smart home. In his spare time, he enjoys playing in rock bands and biking.
