Research
My research area is in the area of computational linguistics, or natural language processing. I have focused my work in two major areas: computational morphology and semantic disambiguation. In particular, I have spent a lot of time looking at how these problems are the same/different across different languages.

For my doctoral thesis, I developed a multilingual, minimally supervised morphological analyzer for Spanish, Portuguese, French, Catalan, Occitan, Italian, Romanian, Latin, English, German, Dutch, Danish, Norwegian, Swedish, Icelandic, Czech, Polish, Russian, Irish, Welsh, Greek, Hindi, Sanskrit, Estonian, Finnish, Turkish, Uzbek, Tamil, Basque, Tagalog, Swahili, and Klingon.
I have also published in areas outside of natural language processing:
