Students conduct their research at INSTAAR, but INSTAAR is not a degree-granting department.
Students should register for a degree program in one of the departments associated with INSTAAR: Anthropology, CEA Engineering, Environmental Studies, Ecology and Evolutionary Biology, Geography, Geological Sciences, or Atmospheric and Oceanic Sciences. Some students choose to participate in interdepartmental programs like Hydrological Sciences or the Certificate in Oceanography as well.
Contacting INSTAAR faculty working in your areas of interest is a good first step. They can tell you before you apply if they are accepting new students, and help answer your questions about departments as well as INSTAAR.
Each INSTAAR faculty member also has a full-time appointment in a department. It is not required that a student be in the same department as the INSTAAR faculty member supervising their research, but it does make parts of the process, like choosing an advisor and assembling a thesis committee, much more straightforward.
