Research

I help manage a department of 70 Artificial Intelligence Engineers at The MITRE Corporation, including a Human Language Technology group. This group provides expertise in a broad variety of computational linguistics, or the use of computers for linguistic applications or research. Our researchers work on projects addressing character recognition, language/script identification, transliteration, name-matching, machine translation, parsing, entity extraction (who/what/when/where), information retrieval, speech recognition/synthesis, dialogue systems, and multimodal human-computer interfaces, all in a variety of natural languages. Independent of the above topics are the type of expertise we apply, including basic research, application of existing products, and technology evaluation.

My own research at MITRE has focused on multimodal conversational systems, including the contribution of gesture and intonation to discourse. Exploring these phenomena has required investigating tools for analyzing and annotating video, and I've recently co-organized several workshops on this topic. Papers on these issues, as well as on a number of my other research interests, can be found on my Publications page.

I'm also an adjunct faculty member in Georgetown's Department of Linguistics, and have recently taught graduate seminars in Tone and Intonation (Spring 2006) and Gesture and Language (Spring 2007). I'm currently (Fall 2008) co-teaching, with Linda Van Guilder, a hands-on graduate course in Multimodal Dialogue Systems. I also teach an introductory graduate course in Descriptive Linguistics in George Mason University's Department of Linguistics (Fall 2007, Spring 2009).
