Joshua Gancher

I am a postdoc at Carnegie Mellon University, advised by Bryan Parno. I obtained my PhD from Cornell University, co-advised by Elaine Shi and Greg Morrisett.

My research is about using techniques from formal methods and program verification to certify cryptographic implementations and proofs.
