With my advisors François Pottier and Jacques‐Henri Jourdan, we aim at establishing a program logic for proving correctness of Multicore OCaml programs. For that, we are using the Coq proof assistant and the Iris separation logic.

Research interests: functional programming, proof of programs, multicore programming, type systems…

Glen Mével, Jacques-Henri Jourdan, and François Pottier. Time credits and time receipts in Iris. In Luis Caires, editor, European Symposium on Programming (ESOP), volume 11423 of Lecture Notes in Computer Science. Springer, April 2019. [PDF]
We present a machine-checked extension of the program logic Iris with time credits and time receipts, two dual means of reasoning about time. Whereas time credits are used to establish an upper bound on a program's execution time, time receipts can be used to establish a lower bound. More strikingly, time receipts can be used to prove that certain undesirable events — such as integer overflows — cannot occur until a very long time has elapsed. We present several machine-checked applications of time credits and time receipts, including an application where both concepts are exploited.
I gave a companion talk at ESOP 2019. [PDF of the talk] The Coq proofs are available here.
