One key paper must be cited as evidencing the contributions, though a body of papers may be discussed in the nomination. The qualifying key paper must have been published in English in a peer-reviewed journal within the three calendar years preceding the award year. Either the candidate must be a graduate student or the key paper must have been published no more than three years after the candidate received their PhD. The committee may consider exceptions to the three-years-from PhD rule, for career interruptions or delays occurring, e.g., for child bearing, child rearing, or elder care.
For the 2025 award, the paper must have been published between the dates of January 1, 2022 - December 31, 2024. The candidate must have been awarded their PhD no earlier than 2019.
