The Earth and Environmental Sciences Ph.D. program is a competitive full-time program offered through the Graduate School of Arts and Sciences with opportunities for students to specialize in aqueous and environmental geochemistry, atmospheric science, biogeoscience, climate science, geology, marine geology and geophysics, paleoclimatology and paleoceanography, paleontology, physical oceanography, seismology and solid earth geophysics, and solid earth geochemistry. The goal of the program is to train broadly educated Earth scientists for careers in academia, research, government, and industry.

During their course of study in the program, students will earn an M.A., M.Phil., and Ph.D.

For our PhD program, passion about the Earth and environmental sciences is the main ingredient we are looking for in students. We often admit students lacking key background courses (math or chemistry for instance), who take those classes the summer before or during their first semester of enrollment. All of our Ph.D. students in good standing are guaranteed graduate fellowships covering 12 months of salary for 5 years. Moreover, to give students a measure of independence and flexibility, each one receives a research allowance of $1000 per year.

The Department of Earth and Environmental Sciences also sponsors a free-standing master's program in Climate and Society.
