I am an associate professor in Natural Language Processing at the University of Stavanger, where I am part of the Information Access & Artificial Intelligence (IAI) research group. Previously, I was a researcher at the Université Grenoble Alpes and a member of Modélisation et Recherche d’Information Multimédia team, working with Philippe Mulhem and Lorraine Goeuriot. Before that, I was a postdoc at the University of Maryland working with Doug Oard. I was a member of UMIACS and the Computational Linguistics and Information Processing (CLIP) lab there. I completed my PhD in computational linguistics at the Institute of Formal and Applied Linguistics at Charles University in Prague where I was advised by Pavel Pecina.

I have been working on a wide range of information retrieval and natural language processing problems and I particularly enjoy working on interdisciplinary research and applications. My main research focus is cross-language information retrieval and multimedia, speech and video retrieval.
