My History & Profile

I am currently a Research Assistant at Idiap Research Institute under the supervision of Dr. Andrei Popescu-Belis and Prof. Herve Bourlard and registered as PhD student in the Electrical Engineering (EDEE) doctoral program at EPFL since August 2014. Before Joining Idiap I attended RWTH Aachen in Germany and received my Masters degree in Media Informatics in 2014.

My research focuses on machine translation and natural language processing. I am mainly interested in combining the techniques of machine learning with linguistic rules (e.g syntacit/semantic/ambiguity/co-reference information) in order to improve machine translation of different language pairs. My project is part of a multiinstitutional collaboration under the SNF-funded MODERN project between Idiap, the University of Zuerich and the Utrecht University in the Netherlands.

My research interests in machine translation, natural language processing, machine learning and related areas.
