Noémie Elhadad Assistant Professor Department of Biomedical Informatics Columbia University 622 W. 168th Street, VC-5 New York, NY 10032 noemie @ dbmi.columbia.edu

My research interests are in natural language processing, with particular focus on text summarization and statistical text generation. I investigate ways in which clinical texts (these include scientific articles, medical textbooks and patient notes) and health consumer texts (health news stories, educational health documents and peer-patient forum posts) can be processed automatically to enhance access to relevant information for physicians, health researchers, and health consumers alike.

Until Fall 2005, I was a Computer Science doctoral student at Columbia University in the Natural Language Processing group headed by Prof. Kathleen McKeown. In 2006, I was an assistant professor in the Computer Science department of The City College of New York. I moved to DBMI in Fall 2007.
