Preliminary Interview

Matriculating students are given an oral preliminary interview prior to the beginning of the fall semester of their first year. Students review their background with their academic advisor and other faculty whose research is related to the student's interests. Courses and possible research advisors are suggested to the student.

About APS

The goal of the APS graduate program is to train the next generation of scientists through both coursework and research. Before applying, we encourage you to view our graduate Program Information page to learn about the components of a Ph.D. at CU and the typical timeline for graduate student careers. While enrolled, graduate students in the APS department are financially supported through a combination of Teaching and Research Assistantships, covering all tuition and a personal stipend sufficient to live in the Boulder area.

Our graduate program integrates astrophysics, planetary science, solar physics, space physics, and space instrumentation with strong observational and theoretical components. These assets facilitate interaction and collaboration between the disciplines and enable students to explore a wide variety of research areas. In addition, the Sommers-Bausch Observatory on campus provides excellent hands-on experience with telescopes and observing. The Department supports the world-class Fiske Planetarium, which offers a unique opportunity for public outreach. Other affiliated research organizations in Boulder complement these campus resources. The Department of Astrophysical and Planetary Sciences values contributions from scientists of diverse backgrounds and aims to promote an inclusive environment for all people.

Opportunity for Underrepresented Students

The Colorado Advantage Graduate Preview Weekend gives underrepresented students a chance to visit the campus, meet faculty, and preview doctoral programs in science, math, and engineering departments at CU-Boulder, including ours.
