Dan Klein is a professor of computer science at UC Berkeley (Ph.D. Stanford, MSt Oxford, BA Cornell). His research on natural language processing creates computer systems that use statistical models to automatically acquire and process human languages. Examples include large-scale systems for language understanding, information extraction, and machine translation, as well as computational linguistics projects, such as the reconstruction of ancient languages. Klein's honors include a Marshall Fellowship, a Microsoft New Faculty Fellowship, a Sloan Fellowship, an NSF CAREER award, the ACM Grace Murray Hopper award for his work on grammar induction, and multiple best paper awards.
