I am an Associate Professor in the Mathematics Department at the University of California, Irvine and am a member of the group in Logic and Foundations.
I also hold a courtesy appointment in the Department of Logic and Philosophy of Science.
I currently have a NSF CAREER Grant in Model Theory and Operator Algebras.
My new book Nonstandard methods in Ramsey theory and combinatorial number theory
(joint with Mauro Di Nasso and Martino Lupini) is now available.
