How to Apply

**Fee waivers are available to eligible students through the university. Priority is given to U.S. citizens/permanent residents. Due to the limited number of available waivers, fee waivers for international students are extremely rare. Please explore the fee waiver information**

Applications are accepted from candidates who intend to pursue the Ph.D. degree. We don't have a MS degree program. Applications are submitted online with an application fee, paid by credit card.

The electronic application can be found on the Graduate Admissions page. The web-based application allows applicants to save entries and return several times for edits before submitting the application. The application fee is $125 for U.S. citizens, permanent residents, and international applicants.

Women, underrepresented minority candidates, LGBTQ students, first generation college students, as well as individuals with disabilities are encouraged to apply.  Learn more about our culture and equity & inclusion.
