About the Program


EAPS is a multidisciplinary department in the College of Science offering graduate research programs leading to the Master of Science (MS) and Doctor of Philosophy (PhD) degrees. The program’s research uses mathematics, physics, chemistry, biology, statistics, and computer modeling to address some of the most challenging interdisciplinary questions about the past, present, and future state of the earth and planetary systems. Many of the research programs include field work in the U.S. or abroad. The department is equipped with state of the art computer and laboratory facilities for calculation, visualization, and experimentation. Former students are now employed by major research institutions, liberal arts colleges, government agencies, and industry. 

Graduate research areas include:

  • Atmospheric and Climate Sciences
  • Environmental Geoscience
  • Geodata Science Initiative
  • Geology and Geophysics
  • Planetary Science

Program Requirements


30 Credits Required

Required Courses (6 credits)


Student must attend EAPS 69100, the colloquium seminar, and write a brief summary of at least seven seminars attended per semester for two semesters.

GPA Requirements


Students are expected to maintain a minimum cumulative GPA of 3.0/4.0. Failure to do so will result in the student being identified as “Less Than Good Standing” in academic standing by the University. Students so identified will not be awarded a degree. A student remaining in “Low” academic standing for three consecutive semesters will be notified by the EAPS Graduate Committee to terminate their program.

The courses should generally be 500/600-level but a maximum of 6 credits at the 300/400-level are allowed. A maximum of 6 credits of independent study are allowable in the 18 credit minimum. Students must take a minimum of 9 credits of EAPS courses.
