Interests
I apply the first principles of type theory, and increasingly, statistical machine learning, to design programming languages and programming environments for scientists and other skilled end-users (e.g. engineers, data analysts and artists). My goal is to design programming languages and environments that are more:
  • adaptable
    Library providers should be able to modularly install library-specific syntactic forms and editor services.
  • reasonable
    There should be clear abstract reasoning principles available to programmers as they read and edit programs.
  • predictive
    The programming environment should combine statistics gathered from a corpus of other programs with a semantic understanding of the program being written to help predict the edit actions that the programmer intends to perform.
