Recent Projects LORELEI My current position at the CMU Language Technologies Institute involves coordination of human and linguistic input, and the generation of linguistically-aware word representations, for the ARIEL-CMU team in the DARPA LORELEI project. In LORELEI, teams participate in a surprise language evaluation, developing machine translation, entity-detection and linking, and information extraction systems within a constrained timespan (e.g. 17-28 days) in unfamiliar languages. Gitxsan/English Online Dictionary I was the lead designer and programmer for the Gitxsan/English Online Dictionary, which uses advanced search and a modern user-interface to solve some of the perennial problems that face users of low-resource language dictionaries. Totem Field Storyboards I was the site manager for the Totem Field Storyboards project, a collection of language-neutral comic-style stories intended for linguistic fieldwork and language education. Each storyboard is carefully constructed to draw out a particular semantic phenomenon. I am also one of the editors of the forthcoming open-access, peer-reviewed journal Storyboards for Linguistic Fieldwork. North American Computational Linguistics Olympiad I help run the North American Computational Linguistics Olympiad, a contest that introduces U.S. and Canadian high-school students to linguistics and computational linguistics. As the lead curriculum designer, I've published over 35 fun age-appropriate linguistics problem sets and served as an editor for many more. International Linguistics Olympiad I am the archivist and webmaster for the International Linguistics Olympiad, the international finals round for high-school linguistics competition.

Other Papers NACLO Style Guide (v6) "Linguistics Olympiad" problems -- age-appropriate problem sets in linguistics for middle- and secondary-school students -- are a distinctive genre with their own rules of composition. This document is a normative "style guide" for the North American Computational Linguistics Olympiad, detailing the criteria that NACLO editors use when choosing a problem for publication.
