*Self-supported NIMBioS visitor

Visitors work on-site at NIMBioS and may link the visit with a Working Group or other activity at NIMBioS. Visitors receive reimbursement for travel and housing expenses as well as a per diem.

Applications can include any type of interdisciplinary synthesis project, but NIMBioS particularly welcomes collaborative projects. Such collaborations might involve NIMBioS resident researchers or staff or local researchers; joint applications from two or more researchers to spend time together at NIMBioS; or applications from participants in other NIMBioS activities to work on their project with NIMBioS computational science staff.

Applications are considered four times a year, with deadlines on March 1, June 1, September 1, and December 1. Applications are evaluated in terms of both the scientific value of the project and the qualifications of the applicant. Particular priority is given to students and junior researchers.
