From Categorical Logic to Facebook Engineering

I chart a line of development from category-theoretic models of programs and logics to automatic program verification/analysis techniques that are in deployment at Facebook. Our journey takes in a number of concepts from the computer science logician's toolkit -- including categorical logic and model theory, denotational semantics, the Curry-Howard isomorphism, sub structural logic, Hoare Logic and Separation Logic, abstract interpretation, compositional program analysis, the frame problem, and abductive inference.
