Thesis Advisors

Our Earth and Planetary Sciences Graduate Program is comprised of UC Davis faculty, federation and emeriti. While only members of the Earth and Planetary Sciences Graduate Program (EPSGP) can be Thesis Advisors for our graduate students, non-members of the EPSGP may help in mentoring students on specific aspects of their projects.
