I am a machine learning graduate student in Computer Science at the University of Wisconsin-Madison. I work with Professor Jerry Zhu on several projects in semi-supervised learning, natural language processing, and computational cognitive psychology. I plan to finish my PhD in the Summer of 2010, with a dissertation entitled New Directions in Semi-Supervised Learning. Please see my research page and list of publications for more details.

6/09 I posted several new sets of slides and posters on the publications page.

Short Biography

I grew up in Hastings-on-Hudson, NY and received a B.A. in Computer Science from Amherst College in 2003. After college, I worked for two years at Deitel & Associates, where I helped write, edit, and build code for introductory CS textbooks. Since 2005, I've been a graduate student in the wonderful city of Madison.
