The 2026 Alonzo Church Award for Outstanding Contributions to Logic and Computation
CALL FOR NOMINATIONS
Deadline 2026 April 17
INTRODUCTION
An annual award, called the Alonzo Church Award for Outstanding Contributions to Logic and Computation, was established in 2015 by the ACM Special Interest Group for Logic and Computation (SIGLOG), the European Association for Theoretical Computer Science (EATCS), and the European Association for Computer Science Logic (EACSL). The award is for an outstanding contribution represented by a paper or by a small group of papers published within the past 25 years. This time span allows the lasting impact and depth of the contribution to have been established. The award can be given to an individual, or to a group of individuals who have collaborated on the research. For the rules governing this award, see <

THE 2025 AWARD
The 2025 Alonzo Church Award was given to Paul Blain Levy for his fundamental study of effectful λ-calculi through the Call-by-Push-Value (CBPV) calculus, which has had major impact on logical calculi, programming language semantics, and their applications to computer science.
ELIGIBILITY AND NOMINATIONS
The contribution must have appeared in a paper or papers published within the past 25 years. Thus, for the 2026 award, the cut-off date is January 1, 2001. When a paper has appeared in a conference and then in a journal, the date of the journal publication will determine the cut-off date. In addition, the contribution must not yet have received recognition via a major award, such as the Turing Award, the Kanellakis Award, or the Goedel Prize. (The nominee(s) may have received such awards for other contributions.) While the contribution can consist of conference or journal papers, journal papers will be given a preference.
Nominations for the 2026 award are now being solicited. The nominating letter must summarise the contribution and make the case that it is fundamental and outstanding. The nominating letter can have multiple co-signers. Self-nominations are excluded. Nominations must include: a proposed citation (up to 25 words); a succinct (100-250 words) description of the contribution; and a detailed statement (not exceeding four pages) to justify the nomination. Nominations may also be accompanied by supporting letters and other evidence of worthiness. Nominations for the 2026 award are automatically considered for all future editions of the award, until they receive the award or the nominated papers are no longer eligible.
PROCEDURE AND DEADLINE
Nominations to the 2026 Alonzo Church Award, taking the form of a single PDF file, should be sent by 2026 April 17 to Marcelo Fiore <
