Individual Interdisciplinary Doctoral

Be Unique

Washington State University’s individual interdisciplinary doctoral degree is a unique program, designed by you, to meet your individual interests. While many universities offer interdisciplinary degrees, very few offer one that is individually designed and able to meet the distinct needs, interests, talents, and career goals of each person.

IIDP students work on a broad range of topics, bridging many disciplines, as highlighted by the research topics of current students (see below). In their Ph.D. studies, IIDP scholars have addressed many important problems facing society—problems that are too complicated for a single discipline, and must be tackled by successfully integrating the perspectives of multiple disciplines.

Students who have earned IIDP Ph.D. degrees have gone on to successful careers in academic research and administration as well as the public and private sector. See some examples HERE.
