I am now at the University of Stuttgart, Germany. Please visit my web page there for the most up to date list of publications.

Research Interests

Natural Language Processing: statistical machine translation, hybrid machine translation, cross-lingual information retrieval, statistical parsing of syntax and discourse, language modeling, morphology, information extraction, topic detection, automatic evaluation

Machine Learning: structured prediction, semi-supervised learning, unsupervised learning, hybrid discriminative and generative models
