Fields of Study

Fields include geochemistry and petrology, geophysics, ice physics, mineral physics, seismology and geodynamics, structural geology and tectonics, paleontology and paleoecology, oceanography, meteorology, cryospheric dynamics, and climatology.

Students admitted in 2020 or earlier have the option of receiving a degree in either geology and geophysics or Earth and planetary sciences. Students admitted in 2021 and subsequent years will receive a degree in Earth and planetary sciences.

Special Requirements for the Ph.D. Degree

There is no formal language requirement and no required curriculum. Students plan their course of study in consultation with their adviser to meet individual interests and needs and to lay the foundations for dissertation research. At the end of the first year the faculty reviews the standing of each student. A student recommended for continuation in the Ph.D. program will be so notified. Some students may be encouraged at that time to pursue only the M.S. degree. At the end of the second year the faculty reviews each student’s overall performance to determine whether the student is qualified to continue for the Ph.D. degree. In order to qualify, a student must have met the graduate school Honors requirement and maintained a better than passing record in the areas of concentration. Also, a student must have satisfied the requirements of the Qualifying Exam by having completed two Research Discourses termed (according to their degree of development) the Minor and the Major Discourses. The Major Discourse will be presented at the Qualifying Presentation, followed by an extended question period wherein the student must successfully defend both Discourses. Remaining degree requirements include a dissertation review in the third year; the preparation and defense of the dissertation; and the submission of the dissertation to the graduate school.

Teaching experience is regarded as an integral part of the graduate training program in Earth and Planetary Sciences. For this reason, all students are required to serve as teaching fellows for two terms during the course of their predoctoral training. Students who require additional support from the graduate school must teach additional terms, if needed, after they have fulfilled the academic teaching requirement.

In addition to all other requirements, students must successfully complete EPS 7100, Responsible and Ethical Conduct of Research, prior to the end of their first year of study.

EPS 7410a, The Origin of Bilaterian AnimalsBhart-Anjan Bhullar

The nature of the bilaterian ancestor—the ancestor of all animals except sponges, comb jellies, jellyfish, and acoel flatworms—is one of the enduring mysteries in evolutionary biology and paleontology. Only in the last decade has some consensus emerged on bilaterian phylogeny. Meanwhile, further insights into various bilaterian clades have been made possible using anatomical, developmental, and genetic data. However, these new sources of information have not been mustered in an attempt to revisit the question of the ancestral bilaterian’s characteristics. In this seminar, we read selected papers on the biology of the major bilaterian clades, including recent evolutionary developmental and paleontological work, and attempt collaboratively to build a character dataset that permits us to reconstruct the features of the ancestral bilaterian. Prerequisite: introductory biology including phylogenetic thinking.
