Roles and Responsibilities of Psi-k Working Groups and their Leaders

Psi-k and its mission

Psi-k is a Europe-based, worldwide network of researchers working on the advancement of first-principles computational materials science. Its mission is to develop fundamental theory, algorithms and computer codes in order to understand, predict and design materials properties and functions. Theoretical condensed matter physics, quantum chemistry, thermodynamics and statistical mechanics form its scientific core. Applications encompass inorganic, organic and bio-materials, and cover a whole range of diverse scientific, engineering and industrial endeavours. Key activities of Psi-k are the organisation of conferences, workshops, tutorials and training schools as well as the dissemination of scientific thinking in society.

Working groups

As a grassroots movement Psi-k relies heavily upon working groups to represent the views of the community and to organise activities to deliver its mission. Each working group should normally consist of five members (including the leader) chosen together to be representative of that whole area.

The trustees value diversity and the different perspectives that people from different backgrounds bring to the Psi-k community. They are keen to ensure equality of opportunity and to promote diversity amongst the working group leaders and members. To make progress towards gender equality, each working group will be expected to have at least one male and one female member.

The working group is normally asked to serve for the period between major Psi-k Conferences (typically five years). Each working group will organise a ‘community meeting’ at the Psi-k Conference at which the new working group leader and members are elected. Working group leaders should not serve more than one consecutive term of office. Working group members who have delivered their commitments may serve for more than one term.

New working groups may be proposed to the Psi-k trustees at any time by emailing [email protected].

Working group leaders

Each working group should normally have one elected leader. Leaders should be members of the Psi-k community who are established experts in the area of the working group and have a reputation for reliability in organisation.

The roles and responsibilities of working group leaders include:

• attending the annual meeting of the Psi-k Scientific Advisory Committee and submitting a brief written report about activities from the past year and proposed for the coming year;
• coordinating the working group and representing their views, eg., when assessing workshop proposals;
• actively encouraging the submission of proposals for workshops associated with the working group, with the expectation of at least one proposal per year primarily associated with the working group;
• liaising with cognate working groups to coordinate and encourage joint activities;
• organising an annual meeting of the wider working group community to be hosted either at a workshop primarily associated with the working group or at the annual German Physical Society meeting, except in the year of a major Psi-k Conference when all working groups will be expected to host community meetings there.

Working group members

The roles and responsibilities of working group members include:

• actively participating in the assessment and ranking of workshop proposals relevant to the working group;
• attending the meeting which hosts the annual working group community meeting;
• submitting workshop proposals primarily associated with the working group, with the expectation that agreeing to join the working group involves a commitment to propose at least one workshop during the lifetime of the working group (typically five years).
