Guidelines Prix Schläfli 2020

Rewarding the best Swiss PhDs in the natural sciences

The Swiss Academy of Sciences (SCNAT) awards the Prix Schläfli for excellent scientific articles resulting from PhDs. In 2020, four prizes will be awarded according to the following disciplines:

  • Biology
  • Chemistry
  • Geosciences
  • Astronomy

The last discipline rotates annually between Mathematics, Physics, and Astronomy.

Articles on clinical and pharmaceutical research are beyond the scope of the Prix Schläfli and will not be considered.

A jury is established for each of the four areas in order to evaluate the candidates and choose the laureate.

Eligibility is limited to young researchers who did their doctoral thesis at a Swiss university, or Swiss nationals who completed their doctoral thesis abroad. Candidates must have defended their doctoral thesis between 1 November 2016 and 31 October 2019. Nominations may only be submitted by the candidate’s doctoral supervisor or by the president of an SCNAT member society.

Only one nomination may be submitted according to one of the four disciplines recognized by the Prix Schläfli, even if the article in question fits multiple disciplines.


Only complete applications in English will be considered. Nominations must be submitted using our online form before 31 October 2019, including the following documents:

  • Motivation letter from the doctoral supervisor or the president of the SCNAT member society nominating the candidate (max. 2 pages). The supervisor or the president must specify the contribution of the nominee if the article in question has multiple authors.

The prize consists of CHF 5,000 plus support for participation at a venue in one of the scientific fields.
