Combined Ph.D. Information
Environment offers a combined PhD in conjunction with Anthropology.
The Graduate School's academic calendar lists important dates and deadlines related to coursework, registration, financial processes, and milestone events such as graduation.
Students must register every term in which they are enrolled in the Graduate School. Registration for a given term takes place the semester prior, and so it's important to stay on top of your academic plan. The University Registrar's Office oversees the systems that students use to register. Instructions about how to use those systems and the dates during which registration occurs can be found on their registration website.
Standardized Testing Requirements
GRE is optional. Please check the program website for more information.
English Language Requirement
TOEFL iBT or IELTS Academic is required of most applicants whose native language is not English.
You may be exempt from this requirement if you have received (or will receive) an undergraduate degree from a college or university where English is the primary language of instruction, and if you have studied in residence at that institution for at least three years.
Combined Degree Program Application Deadline
*The deadline to submit an application to a combined program is always the earlier deadline of the two individual programs, or December 15, whichever comes first.
PhD Stipend & Funding
