My research interests are Machine Learning, Natural Language Processing, and Information Retrieval and Extraction. In particular, I am interested in the application of these to problems in the Social Sciences and Humanities.
At ETS, I am the lead developer on the TextEvaluator (formerly SourceRater) project. I have also made significant contributions to e-rater and fairly small contributions to SpeechRater.
At Stony Brook, I worked with Professor Amanda Stent in the HCI Lab. For my thesis, I developed a Java-based NLP/Machine Learning tool that aims to help students, both native and non-native speakers of English, improve their writing. You can read my thesis, if you'd like.
Over the summer of 2008, I contributed my IR/IE/ML/NLP skills to the PLOG project, as overseen by Professors Stent and Rob Johnson, and Mike Hart. I made recommendations on NLP tools for the project and worked on a section known as Affinity-Based Access Control (ABAC), in which blog entries are only shared with others who have a common interest in the entry's topic.
In the summer of 2007, I participated in the Data Sciences Summer Institute at the University of Illinois at Urbana-Champaign, where I worked on a project that explored the Virtual Web as a finite-state graph. A presentation on my work can be found below.

Here is the presentation on my work at the University of Illinois that I gave to my reading group.
I was an Adjunct Instructor at the State University of New York College at Old Westbury for three academic years. The courses I taught were:
While at Stony Brook, I had the pleasure to be a TA for the following courses (which, luckily, match up exactly with my teaching interests):
I am a member the CSA market share at Z Food Farm and an ARPA level member of the host of this website, a.k.a. the "PBS of the Internet". I drive a Volvo and I'm probably much more excited about it than I should be. ;)
I was the founding Vice-President and Webmaster of Women in Computer Science at Stony Brook, and I used to regularly attend both LUGSB and SBCS meetings. When I was an undergrad at Binghamton, I was a representative on the Student Assembly and was on the Rules Committee as both Vice-Chair and Chair.
I probably spend most of my free time listening to music, and you can get a good feel for my (excellent :) ) musical taste from my last.fm account. When possible, I spend time outside the house playing board games, adventuring around New Jersey and the five boroughs, or going on hikes.
