He has worked in the domain of Human-Computer Interaction and Usability Engineering since 2009 – especially on Voice Output Communication Aids and their emotional expressiveness.

He holds a M.A. in Computational Linguistics.
He studied at the University of Trier, Germany (1997-2005),
and at the University College Dublin, Ireland (2001-2002).

Currently, he is doing his PhD with the preliminary titlte 'What are Implications of Prosodic Speech for Augmented Communicators'. (partially funded by PROMI - Promotion inklusive and the employment centre)

He worked at the Fraunhofer Gesellschaft, Germany: First, at the Fraunhofer-Institute for Algorithms and Scientific Computing SCAI from 2006, and then at the Fraunhofer-Institute Centre Birlinghoven Castle from 2009 till 2014. From 2006 till 2009, he did his duty in the project PHOSPHORUS (Lambda User Controlled Infrastructure for European Research) funded by the European Union – annotating and implementing a Resource Selection Service in the Grid Middleware including the design of ontologies.

He is also certified as a Usability Engineer.
He is disabled (Cerebral Palsy, Dysarthria).
