In addition to work in general philosophy of science, the research activities of the Department are loosely organized into five active Research Groups:
Some of these Groups oversee an Emphasis within the LPS PhD program. These emphases allow students to include graduate seminars in the sciences and in mathematics in their course of study.
LPS enjoys strong cooperative relations with UCI's Department of Philosophy; in particular, the two units jointly administer a single graduate program leading to the Ph.D. in Philosophy. LPS also has strong connections with several science departments, including mathematics, physics, biology, computer science, economics and mathematical behavioral sciences.
