Research Interest

The goal of my research is to create a system which allows humans to talk to machines in the same natural way as to humans. To reach this goal, it is essential to answer the following questions: which properties and abilities must a system have to act in a natural manner, which factors make the behaviour of the system to be perceived as natural, and how may this natural interaction be realized from a technical point of view. In other words, we need to understand all the factors that constitue “natural system behaviour”. This research lies on the intersection of human-computer interaction, computational lingusitcs and artificial Intelligence.

One of my latest reserach is on a novel dialogue model for statistical spoken dialogue systems that is centred around entities and is able to model relations as well as multiple entities. Read the paper and watch the talk.


Short Bio

I am Dialogue Research Lead at Mercedes Benz Research & Development working on the next generation of the Mercedes Benz User Experience. Previously, I was a Research Associate at the Spoken Dialogue Systems Group at the University of Cambridge working with Prof. Steve Young and Prof. Milica Gasic within the EPSRC project “Open Domain Statistical Spoken Dialogue Systems”. I have received my Diploma (MSc) in Computer Science from the Karlsruhe Institute of Technology (Germany) in 2010 and my doctorate in engineering (PhD) at the Dialogue Systems Group at Ulm University (Germany) in 2015. The topic of my dissertation was „User-centred Adaptive Spoken Dialogue Modelling“.

I am currently lecturing in the „Dialogue Systems“ class at Ulm University and co-supervising four doctoral students of their Dialogue Systems Group.
