Degree description
Geological Sciences PhD degree description
The Doctor of Philosophy program in geological sciences is designed to develop creative scholarship in the terrestrial and planetary geosciences. You are encouraged to cross subject boundaries and pursue new understandings of Earth and the solar system.
Why earn your geological sciences PhD at ASU?
Geology at ASU lives inside the School of Earth and Space Exploration, so you study our planet alongside planetary scientists, astrophysicists and instrument builders, while pursuing Earth and other worlds.
A location in the geologically spectacular American Southwest makes ASU an exceptional place to do geoscience. You develop both classic field and lab expertise, and modern computational, modeling and remote-sensing skills --- a combination that opens doors in research, industry and government.
Additional details
As part of the SESE graduate community, based largely on the Tempe campus, you gain access to analytical labs, field programs and the Marston Exploration Theater. You also take part in the SESE colloquium, field trips and research symposia.

Careers this geological sciences PhD degree prepares you for
Graduates are prepared for academic and professional careers in geological science fields such as geochemistry, field geology, geomorphology, structure and tectonics, mineralogy and petrology, geophysics, planetary geology, hydrology, volcanology, Earth observation and remote sensing, and related areas, including geoscience education.
Professionals with expertise in geological sciences are in high demand across sectors and industries, including remote sensing, natural resource management, data science, environmental consulting, economic geology (oil and mining industries), hazard and risk assessment, geophysics and planetary science. Coding and numerical modeling skills translate across many domains, even beyond geosciences. Skills in the measurement and analysis of data related to the physics, chemistry and structures of earthly and planetary systems are valuable to businesses and institutions that rely on data-driven strategies to interact with the planet and explore beyond Earth. The doctoral degree in geological sciences is required for careers in postsecondary education and research.
Career examples include:
- data scientist
- environmental consultant
- geologist
- geosciences professor
- instrument builder
- planetary scientist
- program manager
- research scientist

Frequently asked questions about degree programs
Accelerated programs allow students the opportunity to expedite the completion of their degree.
Accelerated master's
These programs allow students to accelerate their studies to earn a bachelor's plus a master's degree in as few as five years (for some programs).
Each program has requirements students must meet to be eligible for consideration. Students typically receive approval to pursue the accelerated master's during the junior year of their bachelor's degree program. Interested students can learn about eligibility requirements and how to apply.
Concurrent degrees allow students to pursue their own personal or professional interests, earn two distinct degrees and receive two diplomas. To add a concurrent degree to your existing degree, work with your academic advisor.
Joint programs, or jointly conferred degrees, are offered by more than one college and provide opportunities for students to take advantage of the academic strengths of two academic units. Upon graduation, students are awarded one degree and one diploma conferred by two colleges.
ASU adds new programs to Degree Search frequently. Come back often and look for the "New Programs" option.
ASU Online offers programs in an entirely online format with multiple enrollment sessions throughout the year. See https://asuonline.asu.edu/ for more information.
The Western Regional Graduate Program (WRGP) provides a reduced tuition rate to non-resident graduate students who qualify. Visit the WRGP/WICHE webpage for more information: https://graduate.asu.edu/wiche.
