The Topology program supports research on algebraic topology, including chromatic, equivariant, motivic, and (un)stable homotopy, homology and cohomology theories; bordism and K-theory; topological manifolds; knots and links; geometric topology; differential topology; transformation groups; topological quantum field theories; contact and symplectic structures; infinity and model categories; and topological data analysis. Conferences Topology proposals for conferences, workshops, summer/winter schools, and similar activities must be submitted to PD 22-1267 using the "Conference" or “Travel” proposal type in research.gov. The program’ssubmission windows for conference/travel proposalsare September 1-30 and April 1-30. Proposals with budgets not exceeding $50,000 should be submitted during a submission window that occursat least six months prior to the event. Proposals with budget requests that exceed $50,000 should be submitted during a submission window that occursat least eight months prior to the event. Principal Investigators should carefully read the relevant sections of the PAPPG to obtain important information regarding the substance of such proposals and note the additional requirements for travel support requests for international events.

The program in Geometric Analysis supports research on differential geometry and its relation to partial differential equations and variational principles; geometric methods in modern mathematical physics; symplectic geometry; geometric group theory; geometric data analysis; aspects of global analysis, including convex, complex, integral, and information geometries; and related geometric topics.

The Directorate for Social, Behavioral and Economic Sciences (SBE) offers Postdoctoral Research Fellowships to encourageindependence earlyin the fellow'scareerby supporting his or herresearch and training goals.The research and training plan of each fellowship must address important scientific questions within thescope of the SBE directorate and the specific guidelines in this solicitation. The SPRF program offers two tracks: (I) Fundamental Research in the SBE Sciences (SPRF-FR) and (II) Broadening Participation in the SBE Sciences (SPRF-BP). See the full text of the solicitation for a detailed description of these tracks.

Summary: The fiscal year 2026 (FY26) Bone Marrow Failure Research Program (BMFRP) Resource Development Award (RDA) supports the development of a multiomic atlas generated from well-annotated human bone marrow failure (BMF) samples, with omic data derived from marrow specimens. The resulting dataset should serve as an open-access, durable resource for the BMF research and clinical communities and is expected to facilitate key discoveries that advance the understanding of BMF diseases.Distinctive Features: The application must include a robust Data Resource Sharing Plan that describes the means and timeline by which the fully developed resource will be made available to the scientific and clinical community.

Summary: Supports studies that further develop mature ideas, expand upon key discoveries, and have the potential to make significant advances in bone marrow (BMF) failure research and/or patient care. Investigator-Initiated Research Award (IIRA) applications may involve translational and clinical research including studies in preclinical models, research with human data and/or anatomical substances, and research with human subjects, as well as correlative studies associated with a clinical trial(s); however, this award mechanism does not support clinical trials. IIRA applications may also support Investigational New Drug (IND)-enabling efforts such as lead compound characterization, and assessments of formulation and stability, absorption, distribution, metabolism and excretion, dose/response and toxicology.Distinctive Features:This funding mechanism allows for a partnering Principal Investigator (PI). Only the initiating PI will submit a pre-application, but both PIs will need to submit full applications. The partnering PI application is an abbreviated package specific to their distinct portion of the research project. Be advised, all associated applications for a research project may be withdrawn if the initiating or partnering application is rejected or administratively withdrawn.This award mechanism requires preliminary data relevant to the proposed project. Applications can support clinical research studies; however, this mechanism does not allow clinical trials.

Summary: The BMFRP Idea Development Award (IDA) is intended to support innovative ideas and high-impact approaches based on scientifically sound evidence to move toward the BMFRP’s vision of understanding and curing BMF diseases.Distinctive Features:This funding opportunity is open to Established Investigators (EIs) and Early-Career Investigators (ECIs). Reviewers will assess Principal Investigators (PIs) using distinct review criteria based on their eligibility as an EI or ECI.Preliminary data is not required. Applications should demonstrate the ability to achieve interpretable results in the absence of preliminary data supporting the hypothesis.
