The 2026 Alonzo Church Award for Outstanding Contributions to Logic and
Computation
CALL FOR NOMINATIONS
Deadline: 17 April 2026
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 17 April 2026 to Marcelo Fiore
<[email protected]>.
AWARD COMMITTEE
The 2026 Alonzo Church Award Committee consists of the following five members:
Mikolaj Bojanczyk, Thomas Colcombet, Anuj Dawar, Marcelo Fiore (Chair), and
Alexandra Silva.
