This volume contains the proceedings of the Ring Theory Session in honor of T. Y. Lam's 70th birthday, at the 31st Ohio State Denison Mathematics Conference, held from May 25-27, 2012, at Ohio State University. Columbus, Ohio, USA.

Included are expository articles and research papers covering topics such as cyclically presented modules, Eggert's conjecture, the Mittag-Leffler conjecture, clean rings, McCoy rings, QF rings, projective and injective modules, Baer modules, and Leavitt path algebras.

Graduate students and researchers in many areas of algebra will find this volume valuable as the papers point out many directions for future work; in particular, several articles contain explicit lists of open questions.
