Research (needs updating)
In a broad sense, my research aims to improve performance in natural language processing by developing more linguistically-informed approaches and models, drawing on my background as a linguist, particularly in the areas of syntax, semantics and discourse. I have two main areas of research: computational linguistics for low-resource languages (CL4LRL), and computational discourse and semantics.

Computational linguistics for low-resource languages
Methods developed for languages with extensive digital resources are not straightforwardly applicable to under-studied languages, and attempts to adapt such methods raise an obvious-sounding but crucial underlying issue: we will never have the amount of data for these languages that we do for more widely-studied languages. We need to make clever use of the resources we have, considering how to fold linguistic information into data-driven models. My interests in this area are both theoretical and practical, and I am especially interested in the particular low-resource case of endangered language documentation and description. At present, I am interested in facilitating creation of new language resources as well as improving our capacity to develop tools for linguistic analysis of a new language using minimal amounts of data.

Computational discourse and semantics
In this area my recent work has been on semantic role labeling (SRL), mostly in the FrameNet paradigm. Recent work has focused on the interaction between discourse level information and semantic argument structure, aiming both to improve the robustness of SRL approaches and to incorporate more context for labeling individual sentences. In addition to SRL, I work on the automatic classification of situation entities in text, as a step toward better machine handling of discourse-related information.

Other research interests
Other areas of interest include syntax and semantics of Ojibwe (an Algonquian language), grammar engineering (see the OpenCCG project), machine learning and active learning, structure of discourse and the discourse-syntax interface, indigenous languages of the Americas, and relationships between language and music.

PhD thesis    
Semi-Automatic Annotation and Active Learning for Language Documentation (defended October 2009)
My dissertation work uses machine learning and NLP techniques, including active learning, in the context of the documentation and description of endangered languages. With supervisors Jason Baldridge and Katrin Erk and colleague Taesun Moon, I worked on methods for decreasing the time and effort needed to produce interlinear glossed text (IGT) from transcribed texts in language documentation projects. This work was done in part under the auspices of the EARL (Efficient Annotation of Resources by Learning) project.

Music and other interests
French horn

I play French horn with WindMachine (the Saarland University Big Band) and the Saarland University horn quartet. I used to play with the Austin Symphonic Band, a community wind ensemble.

I (used to) play in the Austin Handbell Ensemble, a semi-professional community ensemble. It's unlike anything you've seen or heard before!

These days I attempt my own at-home yoga practice. I used to do yoga at
Yoga Yoga, an Austin studio.
