The Department of Logic and Philosophy of Science (LPS) brings together faculty and students interested in a wide range of topics loosely grouped in the following areas: general philosophy of science; philosophy of the particular sciences; logic, foundations, and philosophy of mathematics; and philosophy of mathematics in application. LPS enjoys strong cooperative relations with UCI’s Department of Philosophy; in particular, the two units jointly administer a single graduate program which offers the Ph.D. in Philosophy. LPS also has strong interconnections with several science departments, including the Departments of Cognitive Science, of Language Science, and of Economics, as well as the School of Biological Sciences, the Donald Bren School of Information and Computer Sciences, and the School of Physical Sciences. The Program in Law and Graduate Studies is a concurrent degree study leading to a J.D. from the School of Law in conjunction with a Ph.D. in the Department of Logic and Philosophy of Science.

Salzburg Exchange Program

LPS and the Department of Philosophy jointly administer an Exchange Program with the University of Salzburg. The program has two parts. The Scholarly Exchange provides opportunities for faculty and graduate students in LPS and Philosophy to visit Salzburg and for faculty and graduate students from Salzburg to visit one or the other of the UCI units. The Program also sponsors joint conferences, held alternately in Irvine and in Salzburg; these are co-sponsored by Salzburg and the UCI Interdisciplinary Program in the History and Philosophy of Science.

To be eligible for the Salzburg Exchange, a graduate student must have advanced to candidacy. The selected student spends one semester in Salzburg, usually teaching one course in the general area of the thesis topic. An upper-division course may be taught in English, but lower-division courses must be taught in German. (Some previous visitors have learned serviceable German by attending a Goethe Institute during the preceding summer.) Typically, a Salzburg visitor will receive a Salzburg Fellowship intended to cover travel expenses, and a stipend; those who teach while in Salzburg will also receive a salary intended to cover living expenses (including health and dental insurance).

Applications from LPS graduate students (including a curriculum vita and syllabi for courses that might be taught) should be sent to the LPS Salzburg Exchange Director by November 1.

Program in Law and Graduate Studies (J.D./Ph.D.)

Highly qualified students interested in combining the study of law with graduate research and/or professional qualifications in Logic and Philosophy of Science are invited to undertake concurrent degree study under the auspices of UC Irvine’s Program in Law and Graduate Studies (PLGS). Students in this program pursue a coordinated curriculum leading to a J.D. degree from the School of Law in conjunction with a Ph.D. degree in the Department of Logic and Philosophy of Science. Contact the PLGS Program Director’s office for additional information at  949-824-4158, or by email to admissions@law.uci.edu.  A full description of the program, with links to all relevant application information, can be found at the School of Law Concurrent Degree Programs website and in the School of Law School section of the Catalogue.
