Typically, grad students of faculty in the Section of Integrative Biology are part of the Ecology, Evolution, and Behavior graduate program (EEB). More information about EEB is found here. For historical reasons, the names of the graduate programs do not reflect the names of the administrative sections (departments) in the School of Biological Sciences. Thus, there is no graduate program in Integrative Biology per se.
Applications to the EEB program are reviewed by a committee; the decision about admitting a student is not made by the prospective advisor.
