Prior Research

I worked with Professor I. Dan Melamed on Machine Translation. More specifically my interests include empirical methods for machine translation, grammar formalisms, MT evaluation, MT system design and implementation, efficient biparsing and discontinuous constituent parsing. My work was part of the Proteus Project at NYU.

    My (outdated) curriculum vitae is available in pdf and ps forms.

    Other Projects

    I am working with some amazing people to get a new non-profit off of the ground called New Rust Exchange. It focuses on using improvisation and improv comedy as a teaching tool for life skills.


  • With over 12 years of directing/performing experience, I am available to teach/coach/perform improv comedy. See what others have said about my work here.

    Current Comedy Groups

  • Cherub Improv All volunteer improv comedy group.
  • Los Banditos Del Canto Musical Improv Comedy performing all around the city.

    Past Comedy Groups

  • NYU Improv Comedy Group: Dangerbox The improv comedy group I started and was the creative director of at NYU
  • Bucknell Improv Group The improv comedy troupe I started and was in for 4 years at Bucknell, but alas, i graduated.
