Welcome to my personal research website. I am currently working as a Postdoctoral Research Fellow in the Language Technology Group of the Department of Informatics, University of Oslo. My research is funded by a 3-years research grant from the Norwegian Research Council.

My general research interest is dialogue modelling and its applications to various language technology tasks. During my PhD, I developed a hybrid approach to dialogue management which combined expert domain knowledge and statistical models into a unified framework. One offspring of my work was the release of the OpenDial toolkit to build robust and adaptive spoken dialogue systems.

In my postdoctoral work, I am now focusing on the use of dialogue modelling for another application domain, namely machine translation. In spite of great progress in the recent years, machine translation remains poor at adapting translations to the relevant context. In order to translate a dialogue (say, film subtitles), current systems typically operate one utterance at a time and ignore the global coherence and structure of the conversation. The goal of this postdoctoral project is to enhance the contextual awareness of machine translation systems by incorporating features from the surrounding dialogue context and exploiting these features to dynamically modulate the translation outputs.

[25/02/2014] I successfully defended my PhD thesis on the 21st of February 2014! Thanks to everyone who contributed to this event [1, 2, 3, video]. Starting from next month, I will work as a Postdoctoral Research Fellow for a 3-years project funded by the Norwegian Research Council.
[12/02/2014] My PhD defense is officially scheduled for Friday, 21st February 2014 at 14:15 (see here for all practical details). I'm honoured to have Kristiina Jokinen, Verena Rieser and Jim Tørresen as opponents. Everybody is welcome to attend!
[31/01/2014] The first public release of the OpenDial toolkit is finally available! OpenDial is a Java-based toolkit to develop robust and adaptive dialogue systems for various domains. The code has recently been fully refactored and includes an easy-to-use graphical interface. The project website also features a user manual for the toolkit.
