Mathematical Logic has a long tradition in the UCLA Mathematics Department going back to the 1940s, with early faculty that included C. C. Chang, Alfred Horn, Max Zorn, and Abraham Robinson. The group’s strengths over the years have been in model and set theory, and the foundations of mathematics.

The group maintains close connections with other mathematical logic groups in southern California, at Caltech and at UC-Irvine, runs several seminars including the Caltech-UCLA Cabal seminar, runs a biweekly Logic Colloquium, and organizes a series of biennial conferences with national and international speakers, known as Very Informal Gatherings of Logicians, which started in 1975.
