This email from Vladimir seems to be from a time when he had just learned more about Coq but had not yet started using it:

Hi Dan,

thanks for the link. I have heard about this one (from coq-club actually on
which list I am since several years ago). All is well with me, all of the
Bloch-Kato papers are submitted to journals for about a year now and many are
accepted. 

I am thinking a lot these days about foundations of math and automated proof
verification. My old idea about a "univalent" homotopy theoretical models of
Martin-Lof type systems survived the verification stage an I am in the
process of writing things up.

I also took a course at the Princeton CS department which was for most part
about Coq and was very impressed both by how much can be proved in it in a
reasonable time and by how many young students attended (45, 35 undergrad +
10 grad!). 

How are you?

Vladimir.
