To further facilitate collaboration in the research community, INTERFACE plans to sponsor a limited number of “collaborative exchanges” for US-based graduate students, in which students who primarily work with models spend a brief period (up to one month) working in an experimental setting, or students who primarily work on global change experiments spend a brief period (up to one month) working in an ecosystem or Earth system modeling setting. These exchanges should ideally allow the student to continue working on a similar topic, but from a different perspective. Interested graduate students should identify a laboratory in which they would like to work, and should secure approvals from their advisor and the exchange lab’s PI. To apply, students should submit as a single PDF file: (1) a two-page proposal explicitly stating the questions being addressed and why the collaboration will facilitate answering them, (2) an NSF-style CV, (3) a one-page budget justification, and (4) letters of support from the advisor and the PI of the lab the student will visit. Applications should be sent to Aimée Classen <firstname.lastname@example.org>. Applications will be reviewed at two times each year, starting on the fourth Monday of April and the fourth Monday of October, through the end of 2014. Allowable expenses include airfare, meals while traveling to and from the exchange location, and housing. These funds cannot be used to cover classes at the host institution or student/ PI salary. Exchanges may be partially or fully sponsored by INTERFACE.
