Division of Integrative Organismal Systems (Core Programs)

Funding Agency:
National Science Foundation

The Division of Integrative Organismal Systems (IOS) supports research aimed at understanding why organisms are structured theway they are and function as they do. Proposals are welcomed in all of the core scientific program areas supported by the Divisionof Integrative Organismal Systems (IOS). Areas of inquiry include, but are not limited to, developmental biology and the evolution of developmental processes, nervous system development, structure, modification, function, and evolution; biomechanics and functional morphology, physiological processes, symbioses and microbial interactions, interactions of organisms with biotic and abiotic environments, plant and animal genomics, and animal behavior. Proposals should focus on organisms as a fundamentalunit of biological organization. Principal Investigators (PIs) are encouraged to apply systems approaches that will lead to conceptual and theoretical insights and predictions about emergent organismal properties.

Eligibility Requirements

Limit on Number of Proposals per PI or Co-PI:

Core Programs Track:

One submission as PI or Co-PI per fiscal year (October 1- September 30) to IOS.

Proposals submitted to the PGRP solicitation, the PBI solicitation or the RUI/ROA Solicitation (NSF 14-579) also count toward the limit for the Core Programs Track.

Rules of Life Track:

One submission as PI or Co-PI per fiscal year (October 1- September 30) to the Biological Sciences Directorate (BIO).

PIs or Co-PIs who submit to the Rules of Life track in IOS may not submit to the Rules of Life track in another division in the Directorate for Biological Sciences. A PI or coPI may only submit one Rules of Life proposal in the Directorate of Biological Sciences in a fiscal year.

In a fiscal year, an individual may participate as a PI or Co-PI on no more than one proposal submitted to the Core Programs track in response to this IOS Core Program Solicitation and no more than one proposal submitted to the Rules of Life track.

There is no limit on the number of proposals per fiscal year that an investigator can participate in as a non-Co-PI lead of a sub-award or Other Senior Personnel. Thus, the number of proposals on which an investigator can be listed as collaborator is unlimited. Proposals in excess of the limit for any person will be returned without review in the reverse order received. It is the responsibility of the submitters to confirm that the entire team is within the eligibility guidelines. Changes to the team post-submission to meet the eligibility limits will not be allowed.

For the purposes of this solicitation senior personnel include the Principal Investigator (PI), any Co-PIs, and as “Other Senior Personnel”, any other researchers actively involved in achieving and managing the intellectual merit or broader impacts goals of the project. Senior personnel may include individuals who will provide essential expertise and intellectual engagement in a small but significant component of the overall project. Named postdoctoral researchers may be considered senior personnel. Students, collaborators, or consultants who provide specific technical expertise on a limited portion of the project are not considered senior personnel.

This limit does not pertain to proposals submitted to other solicitations not associated with the IOS Core Programs track (e.g., EDGE, Research Coordination Networks, CAREER) or to solicitations in other BIO divisions (e.g. Division of Molecular and Cellular Biosciences, Division of Biological Infrastructure, Division of Environmental Biology). However, individual solicitations may have their own limit guidelines; therefore be sure to review those solicitations carefully for details.
