News

  • I am teaching CSCI 544 Applied Natural Language Processing this semester (Spring 2014).
  • I am looking for a summer intern for a project on discourse parsing. If you are a graduate student working on parsing or discourse (or both!) and you want to spend the summer in sunny LA, let me know. Apply here. The deadline is February 16, 2014.
  • I am looking for PhD students in Natural Language Processing or Computational Linguistics. Prospective students should apply directly to the USC Computer Science PhD program by December 1st, 2013.

Research Interests

  • Computational Linguistics.
  • Automatic analysis of child language.
  • Human Language Technology applications (e.g. dialogue systems, information extraction and speech recognition).
  • Multimodal processing and human communication dynamics.

For more details, see my research page and my list of publications.

Current and Recent Activities

  • I am teaching CSCI 561 Foundations of Artificial Intelligence, Spring 2012.
  • I was Syntax and Parsing area co-chair for EACL 2012 (with Xavier Carreras).
  • I was a member of the discriminative language modeling team in the 2011 Johns Hopkins CLSP Summer Workshop.
  • I am an information officer for SIGPARSE, the ACL Special Interest Group on Natural Language Parsing.
  • I co-organize the ICT Machine Learning reading group with Louis-Philippe Morency.

Brief Bio

University of Southern California (2008-present)

I am a Research Assistant Professor at the USC Computer Science Department and a Research Scientist at the USC Institute for Creative Technologies, where I am a part of the Natural Language Dialogue group.

University of Tokyo (2006-2008)

Before joining USC I was a member of Tsujii Laboratory at the University of Tokyo. At Tsujii Lab, I worked on combining discriminative dependency parsing with HPSG, and on applying syntactic parsing in bioinformatics.

Carnegie Mellon University (PhD, 2006)

I got my PhD at Carnegie Mellon University in 2006. My thesis advisors were Alon Lavie (LTI) and Brian MacWhinney (Psychology). The other members of my thesis committee were Lori Levin (LTI), Jaime Carbonell (LTI), and John Carroll (University of Sussex, Department of Informatics).

My research at CMU involved the identification of grammatical relations, or GRs, (such as subjects, objects and adjuncts) in corpora of transcribed dialogs between children and parents. Most of these transcripts came from the CHILDES Database, but I also worked with transcripts from other sources.
