This volume contains the proceedings of the Logic at Harvard conference in honor of W. Hugh Woodin’s 60th birthday, held March 27-29, 2015, at Harvard University. It presents a collection of papers related to the work of Woodin, who has been one of the leading figures in set theory since the early 1980s.

The topics cover many of the areas central to Woodin’s work, including large cardinals, determinacy, descriptive set theory and the continuum problem, as well as connections between set theory and Banach spaces, recursion theory, and philosophy, each reflecting a period of Woodin’s career. Other topics covered are forcing axioms, inner model theory, the partition calculus, and the theory of ultrafilters.

This volume should make a suitable introduction to Woodin’s work and the concerns which motivate it. The papers should be of interest to graduate students and researchers in both mathematics and philosophy of mathematics, particularly in set theory, foundations and related areas.
