EAPS Graduate Application Requirements

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. Our 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 our research programs include field work in the U.S. or abroad. Our department is equipped with state of the art computer and laboratory facilities for calculation, visualization, and experimentation. Our former students are now employed by major research institutions, liberal arts colleges, government agencies, and industry. 

Individuals who have not completed a Master's Program acceptable to the EAPS Graduate Committee will normally be considered for initial admission to the Master's Program. However, individuals may apply for direct admission to the Doctoral Program. The MS degree is not a prerequisite for the PhD degree.

To be valid for admission, English proficiency test scores (TOEFL, IELTS) must be no more than two years old at the time the recommendation for admission is received at the Graduate School.
