Ideal Applicant

Researchers, training programs, conference organizers, or fellowship applicants working in neurophysiology and allied neuroscience fields, especially programs tied to the Grass Fellowship or similar training/meeting activities.

Good Fit

  • Proposal supports neuroscience training, fellowships, or conference/meeting costs.
  • Project serves early-career neuroscientists or professional development in neurophysiology.
  • Clear alignment with the Grass Fellowship or the Marine Biological Laboratory programming.
  • Willingness to follow the foundation's application instructions and page limits.
  • Geographic or institutional ties to Massachusetts programs where appropriate.

Geography

Restrictive

The latest year’s giving was concentrated in three states but heavily focused on Massachusetts, which received about 89% of 2024 dollars, indicating a locally concentrated footprint despite some out-of-state awards.

Recipient Variety

Moderate

The foundation funded seven distinct recipients in 2024 (and many more in earlier years), showing a mix of recurring large institutional grants and many smaller awards and individual prizes; dollar concentration to a few top grantees is high (top five took 96%).

New Applicants

Broad

A public application portal and guidance are available and five of seven 2024 recipients were new that year (2023 also showed high new-recipient rates), which together suggest unfamiliar applicants can realistically access some of the foundation’s programs, though some funding streams are by preselection.
