Geological Sciences, PhD

At the School of Earth and Space Exploration, students in the geological sciences doctoral degree program are working with faculty and researchers in state of the art laboratories and in the field on all seven continents on Earth.    

Arizona State University is a world leader in the geological sciences. Our research interests range from volcanology, to seismology, and from geochemistry to planetary geology. We encourage our students to cross subject boundaries and pursue new understandings of our Earth and the universe beyond. 

Students in this program have access to NSF-funded labs and instruments including a Secondary Ion Mass Spectrometer (SIMS), an electron Microprobe, a NanoSIMS, an experimental volcanology lab, and the Experimental Petrology and Igneous Processes Center (EPIC).   

Our geological sciences Ph.D. program is designed to develop creative scholarship and prepare students for professional and academic careers in geological science fields such as geochemistry, geology, geophysics, planetary geology, hydrology, and related areas.

Graduate students in geological sciences become part of our NASA- and NSF-funded projects, studying the great unknowns of the Earth and our solar system. We are seeking to answer the most significant questions in science and setting the stage for a new era of exploration.

Degree Overview

The Ph.D. program provides training in experimental and theoretical geoscience research. The degree requires 84 credit hours, a written comprehensive exam, an oral comprehensive exam, a prospectus, and a dissertation. The ideal candidate will have an interest in experimental or theoretical geoscience.

How to apply

The majority of SESE’s admissions are for the fall semester. Spring admissions occur under special circumstances. Graduate admission to SESE consists of the following application dates for full consideration of funding and campus recruitment activities. Applications are encouraged before these dates. Applications received after these dates will still be considered, but generally at a lower priority for funding and visitation.

January 15 of the current year for fall admission
October 1 of the previous year for spring admission

To be eligible for admission to SESE’s graduate program applicants must:

  • have a bachelor’s degree
  • have at least a 3.0 GPA
  • submit general GRE scores; exam must have been taken within last 5 years
  • demonstrate English proficiency via the TOEFL or IELTS, if necessary. More information regarding English proficiency and required scores can be found at https://students.asu.edu/graduate/proficiency

Most applicants will have a degree in an area related to the graduate degree they are seeking, although this is not a requirement. There is not a minimum score requirement for the GRE exams because scores are taken into consideration with the academic record and other materials as a whole. Meeting the minimum criteria does not guarantee admission to the program.
