There is also the substantial work on formal proofs in mathematics using the Cambridge-München
Isabelle prover. There is an archive of formal proofs at https://www.isa-afp.org and the Isabelle
home page is at https://isabelle.in.tum.de/index.html (one of four mirrored sites).

I don't know much about Homotopy Type Theory, but Georges Gonthier was also involved in that, along
with other luminaries such as the logicians Peter Aczel, Per Martin-Löf and Dana Scott
