Oh, hey there, what's up.  I'm an associate professor in the economics department at the University of Toronto.  I work on microeconomic theory, with a particular interest in robustness and other modeling issues in mechanism design.

How to find me

By email: zgabriel.zcarroll@zutoronto.zca, but without the z's.

In person: Unfortunately this isn't really happening these days.

By telephone: Still figuring out how this one works. I'm getting there.
