Visitors at NIMBioS in 2019

NIMBioS supports short-term visitors to NIMBioS for periods up to one week to assist their efforts in carrying out research that conforms to the mission of NIMBioS to foster research at the interface between mathematics and biology. NIMBioS no longer provides financial support for Sabbatical Fellows, but is open to requests for self-supported visits not needing financial support lasting up to several months duration, with the length of stay determined by the objectives of the proposed project.
