Research Interests

I am a cognitive scientist interested in intelligent social robotics. I understand this area as artificial intelligence + social robotics. I combine a variety of methods from social sciences and cognitive science to the design and evaluation of behaviors for social robots.
There is a growing number of machines in the world that can be called robots. Many of these are now deployed in settings in which they will encounter humans on the one hand and other machines like them on the other hand. This is especially noticeable in the growing market of service robotics, where robots already serve various purposes in hospitals or warehouses, for example. To be able to deal with the challenges of working in such essentially social environments, my research is dedicated to equipping machines with "social intelligence". General areas I am interested in are: In the past, I conducted research within the ITALK project, the ECHORD project and the RoboEarth project. The final demo of the RoboEarth project can be seen here. I was also involved in the CITEC Dialogue Demonstrator. A short demo of the system can be seen here.



Winter Semester 2016/2017
LV 64-124 Proseminar Künstliche Intelligenz Alpay, Griffiths, Wermter

For bachelor's or master's theses:
Please contact me regarding possible projects in the areas listed under "Research Interests" and we can discuss your ideas. Currently, I am looking for students who would like to work on natural language generation (NLG), dialogue systems or socially intelligent robots.
