**Eligibility**

To be eligible for the award in year X, a nominated dissertation must have been successfully defended in the period January 1st, X-2 through December 31st, X-1. If the advisor of the dissertation is in the core committee of year X (see below), it cannot be nominated in year X. In this case the eligibility period extends by one year, i.e., a dissertation successfully defended between January 1st, X-3 through December 31st, X-2 is eligible if and only if it was not eligible in either year X-1 or year X-2. The core committee of year X is disjoint from those of years X-1 and X-2. Each dissertation is thus eligible exactly twice. The dissertation must be in English: either originally written in English, or translated. The main topic of the dissertation must be on the principles of Distributed Computing. (For a possible indication of what it is meant by this term, see for example the Call for Papers of DISC and PODC.)

**Nomination and Submission**

A one-page nomination letter must be submitted by the thesis advisor. The nomination should highlight the dissertation’s contributions and justify why the dissertation is worthy of the award. Submission Checklist:

A nomination must include:

- Contact details (affiliation and email addresses) of the advisor and the doctoral student.
- A formal document from the student’s department/institution/organization verifying the date that the dissertation was successfully defended (a scanned version is acceptable for the submission, but the original document might be required at a later stage of the evaluation). If not indicated by the document, also state the period of time the student was enrolled in the doctoral program.
- A one page justification letter.
- The following four lists of work (co)authored by the candidate:
- Publications that contain material from the thesis, detailing what material was taken from which part of the thesis and the parts that are not contained in the thesis.

- Publications that are cited in the thesis, but do not contain material that also appears in the thesis.

- Papers currently under review, including journal submissions of previously published work, that contain material from the thesis, detailing what material was taken from which part of the thesis and the parts that are not contained in the thesis.

- Those parts of the thesis which are not included in the other lists.

- A list of awards the student received for the thesis and/or publications related to the thesis.
- One copy of the dissertation in electronic form (preferably in pdf).
- A separate copy of the abstract in electronic form (either as pdf or plain text).

**Award Committee and Review Process**

The committee will consist of four core members and a number of ad-hoc members, selected as described below. The review process will consist of two stages:

The first selection phase, carried out by the core members, will be based on the nomination letters and publication lists. At the end of this phase, a short list of dissertations to be considered in the second round will be compiled.

Based on the short list, the four core members will identify experts on the topics of the dissertations and invite them to serve as additional (ad hoc) members of the committee. The committee should include sufficiently many members to allow each dissertation to be reviewed by three members without requiring any member to review more than two dissertations.

For an award year X, the four core members will by default be the following:

The PC Chair of DISC in year X-9.

The PC Chair of PODC in year X-9.

The PC Chair of DISC in year X-1.

The PC Chair of PODC in year X-1.

The committee chair will alternate between DISC and PODC PC chairs of year X-9. Specifically, when X is even, the chair will be the DISC PC chair of X-9 and when X is odd, the chair will be the PODC PC chair of X-9.

Members of the committees in years X-1 and X-2 are not eligible for participation in the committee for year X. If a core committee cannot be established (for this or any other reason), the corresponding Steering Committee of the award year nominates a person to work on behalf of the missing DISC/PODC PC chair.

**Evaluation Criteria**

The nominated dissertations will be reviewed for technical depth and significance of the research contributions in the area of Distributed Computing, potential impact on theory and practice, and quality of presentation/writing, including thoroughness of description of related work and understandability of algorithms and proofs.

**Award**

The award presentation will alternate between DISC (even years) and PODC (odd years).

The winning dissertation will receive a plaque and a monetary prize.

The committee reserves the right to split or decline to give the award.

The committee can give Honorable Mentions to up to two non-winning dissertations meriting special recognition (or one Honorable Mention in case the award is split).
