LAOS: Logicians At Ohio State

An interdisciplinary group of scholars with research interests in logic

Welcome to the LAOS members' page. Here you will find brief details about the wealth of different interests of scholars working in logic-related areas at Ohio State. This is a cross-departmental, interdisciplinary grouping with breadth and depth that is hard to match in the English-speaking world. The student seeking instruction in any aspect of Logic is bound to find someone on this list who can help.
