Bio

I'm a post-doc at Cornell, working with Greg Morrisett. My email address is jsarracino@cornell.edu. I defended my PhD at UCSD in 2020, working with Nadia Polikarpova and Sorin Lerner in the Programming Systems group.

My research interests lie at the intersection of Programming Languages (PL), Human-Computer Interaction (HCI), and Security. Here are some of my current and past projects!

  • mirrorsolve: extensible first-order logic in Coq with an SMT solver backend. talk with demo, code.
  • leapfrog: certified, automatic proofs of equivalence for network protocol parsers. blog post, code.
  • mockdown: resizeable visual layouts from input-output examples. replication package, code.
  • spyder: language support for maintaining data invariants. code.
  • eddie: interactive diagrams without coding. online demo, website, code.
