In 2026, the French Academy of sciences and the U.S. National Academy of Sciences will award the Richard Lounsbery Grand Prize valued at $100,000 (including $25,000 to cover one or more stays of scientific cooperation in the USA) to recognize the achievements of a researcher in biology or medicine.
To be eligible, candidates must be 45 years old or younger in 2026 (born in 1981 or later, with a one-year extension per child for women), and be working permanently in a French laboratory.
Nominations may be submitted by any institution or researcher in the field covered by the prize. Direct applications are not accepted.
Applications must be written in English using the online form, and sent by Monday October 20, 2025 by e-mail as a single PDF file (letters of recommendation can be received separately) to the following address: prix@academie-sciences.fr
Based on what NAS says, what is required, and what’s visible from past awardees, here are what tend to correlate with successful nominations / awards:
| Predictor | What It Looks Like / Why It Helps |
|---|---|
| High scientific / scholarly impact | Strong, important discoveries; contributions that have meaningfully advanced a field; papers that are well‐cited or have influenced others. Awardees often have several high-impact works. |
| Selectivity in “best work” | Since the nomination wants a short list of most significant publications, nominees who can pick strong, high-visibility, perhaps paradigm-shifting works tend to do better. |
| Originality / novel ideas | Work that shows creativity, breaking new ground, not just incremental extension. NAS prizes recognize scientific novelty. |
| Growing recognition but not “done already” | Someone who is established enough to have key outputs, but not so saturated with awards that their contributions are taken for granted may be favoured (especially when nomination guidance says “earlier in their career” or “not already heavily recognized”). |
| Strong letters / peer reputation | The nominator’s letter and letters of support are important; being able to show peer recognition (invited talks, leadership, prior awards) helps. |
| Clarity in nomination materials | A well-organized, compelling nomination: clear summary of achievements; how they advanced science; why this person stands out; succinct presentation of key publications. |
| Broader scientific influence / impact beyond niche | Contributions that influence broader areas of science, or have applications; people whose work is visible and has influenced thinking in a field. |
| Potential for future work / continuity | Even for awards, showing that the person is active, with ongoing contributions, or that the work has further implications tends to help. NAS seems to prefer candidates whose work is current and impactful not just in the past. |
To be eligible, candidates must be 45 years old or younger in 2026 (born in 1981 or later, with a one-year extension per child for women), and be working permanently in a French laboratory.
