I research computational methods for style-based analysis of natural language using machine learning and shallow lexical semantic representations, exploring applications in intelligence analysis, forensic linguistics, biomedical informatics, and humanities scholarship.

I am Associate Provost for AI and Professor of Computer Science at Touro University. In addition, I hold a courtesy appointment as a fellow at the Brain Sciences Foundation (Providence, RI). I received my B.Sc. in Applied Mathematics from Carnegie-Mellon (1988) and my Ph.D. in Computer Science from Yale University (1994). I received a Fannie and John Hertz Foundation Doctoral Research Fellowship (1991-94), a Fulbright Postdoctoral Fellowship at Bar-Ilan University (1994-96), and an Israel Science Foundation Immigrant Scientist Fellowship (1999-2002). I was the 2014 Distinguished Visitor in Forensic Linguistics at the Centre for Forensic Linguistics, Aston University, Birmingham, UK, and am a Fellow of the British Computer Society.
