Interdisciplinary Track

For those seeking a second major rich in astronomy content


The Interdisciplinary Astronomy (IDA) major is an ideal second major for students seeking to add astronomy content to their primary degree. It provides the solid scientific background needed for technical positions in astronomy or for careers like teaching, science writing, and outreach.

Students pursuing their primary degree in a science, technology, engineering, and mathematics (STEM) field can add an IDA major with little additional coursework. With appropriate advance planning, humanities students can use it to add a STEM focus to their degree.

The IDA major includes foundational courses in math and physics, but the requirements in these areas are less intensive than for the Academic Track. It is designed to be adapted to each student’s career goals; please meet with an advisor to learn how the IDA major can be customized for you.

If you enjoy astronomy but don’t plan to major in it, an astronomy minor on the Interdisciplinary Track can be a great way to incorporate the field into your existing course of study. Because the physics demands are less intensive than on the Academic Track, it’s often easier for non-science majors to fit an Interdisciplinary Astronomy minor into their schedules. Students interested in this option should meet with the undergraduate advisor to develop a course plan tailored to their goals and interests.
