News

• UPDATE: I'll be working at Twitter starting Oct. 2011
• Our Latent Attribute work got some press coverage:
  • New Twitter Algorithm Could Out Dudes Pretending to Be Lesbians, The Atlantic
  • Another way to tell women and men apart? Tweets, CBS News
  • You Can't Keep Your Secrets From Twitter, Fast Company

Research Interests

I am interested in scalability of learning algorithms and the application of graph theoretic methods to problems in NLP. I've been fortunate to work and publish with some well known people in these fields and have served on the program committees of ACL, EMNLP, IJCAI, AAAI, WWW, and IEEE Pattern Recognition.
