The Astronomy and Astrophysics Research Grants (AAG) program, funded by the National Science Foundation, supports a broad range of research in the astronomical sciences with approximately $50 million awarded annually. The program funds individual investigators and collaborative teams pursuing observational, theoretical, laboratory, and archival data studies.
Research topics span the full scope of astronomy and astrophysics, from stellar physics and planetary science to cosmology and extragalactic studies. Proposals are due November 16, 2026, and are open to unrestricted applicants at U.S. institutions. AAG is the primary NSF mechanism for sustaining the astronomy research community and maintaining U.S. leadership in observational and theoretical astrophysics.

Improving Undergraduate STEM Education: Education & Human Resources (IUSE: EHR) Program is sponsored by National Science Foundation (NSF). This program promotes novel, creative, and transformative approaches to generating and using new knowledge about STEM teaching and learning to improve STEM education for undergraduate students. It supports projects that bring recent advances in STEM knowledge into undergraduate education, adapt, improve, and incorporate evidence-based practices, and lay the groundwork for institutional improvement in STEM education. Professional development for instructors to ensure adoption of new and effective pedagogical techniques is a potential topic of interest.
NSF Small Business Innovation Research / Small Business Technology Transfer Phase I Programs is sponsored by National Science Foundation (NSF). These programs provide non-dilutive funds for use-inspired research and development of unproven, leading-edge technology innovations that address societal challenges. NSF funds broadly across scientific and engineering disciplines and does not solicit specific technologies.
Innovations in Graduate Education (IGE) Program is sponsored by National Science Foundation. The IGE program encourages the development and implementation of bold, new, and potentially transformative approaches to STEM graduate education training. It seeks proposals that explore ways for graduate students to develop skills, knowledge, and competencies needed for a range of STEM careers.
Research Grants is sponsored by The Leakey Foundation. The Leakey Foundation Research Grants support both PhD dissertation research and post-PhD research across multiple disciplines related to human origins, evolution, and behavior. They prioritize funding for exploratory phases of promising new research projects and innovative, multidisciplinary approaches that expand the boundaries of current understanding. Relevant disciplines include archaeology, biological anthropology, paleoanthropology, primate behavioral ecology, genetics, geology, anatomy, morphology, paleobotany, and paleoclimatology. Current funding focus areas include the paleoanthropology of the Miocene, Pliocene, and Pleistocene; primates (evolution, behavior, morphology, ecology, endocrinology, genetics, isotope studies); and modern hunter-gatherer groups.
Fire Science Innovations through Research and Education (FIRE) program is sponsored by National Science Foundation (NSF). This program invites innovative multidisciplinary and multisector investigations focused on convergent research and education activities in wildland fire. It supports research that can inform risk management and response, adaptation, and resilience across infrastructures, communities, cultures, and natural environments. Relevant topics include developing novel materials and methods for retrofitting existing buildings and remediating buildings following wildfire and smoke events.
