Collaboration and Sponsors

While we often picture astronomers as lone souls peering through a telescope, building, carrying out, and analyzing an ambitious survey such as DES requires a large, coordinated team.  DES is an international project with over 400 scientists from 25 institutions in 7 countries, who have come together to carry out the survey.  Our team of scientists comprises university faculty and researchers, laboratory and observatory staff scientists, post-doctoral researchers, and graduate and undergraduate students. The support staff are also a critical part of the team: they make it possible for our scientists to travel to Chile to observe for the survey and to travel to conferences and collaboration meetings to discuss the latest results.

Science Working Groups and Conveners

Our scientific efforts are organized into Science Working Groups, each of which is tasked with coordinating and leading analyses and projects that feed into the larger questions of cosmic acceleration and expansion as well as other science topics. The co-coordinators of the Working Groups make up the Science Committee, which coordinates the analysis across working groups. The Science Working Groups, and their conveners, are:

Galaxy Clusters: Sebastian Bocquet & Matteo Costanzi
Galaxy Evolution & QSO: Xin Liu & Antonella Palmese
Large-Scale Structure: Anna Porredon & Santiago Avila
Milky Way: Burçin Mutlu-Pakdil & Andrew Pace

The Science Committee is coordinated by Chihway Chang & Michael Troxel.

Richard Kron from the University of Chicago and Fermilab was appointed the new Director of the Dark Energy Survey in October 2018.  He leads the Project/Collaboration Office, which oversees all aspects of the Project and Collaboration. Tom Diehl is the Deputy Director. The Management Committee oversees collaboration affairs and oversees a number of committees:

Publication Board: Klaus Honscheid
Membership Committee: Eusebio Sanchez
External Collaborators: Paul Ricker
Speakers Bureau: Rich Kron
Early Career Scientists: Zhou Conghao, Rebecca Chen, Jack O’Donnell, Johnny Esteves and Rafaela Gsponer.
Education and Public Outreach: Ross Cawthon
Diversity & Inclusion: Alex Alarcón 
Collaboration Meeting Steering Committee: Don Petravick


The ombudspersons provide confidential, informal, independent, neutral advisory services for anyone in DES, including aid in resolving disputes. They are assigned by the Director. We also count on two external, professionally trained mediators are offering their services to DES. The advisory board observes and takes feedback on a range of topics, and gives strategic advice to the Director.

Ombudspersons:  Kathy Romer, Ting Li, and Kyler Kuehn.
External mediators: Julian Mayers (University of Sussex) and Katrina Abatis (ETH Zurich).
Advisory Board: Bhuvnesh Jain & David Weinberg

Executive Committee

The Executive Committee manages all aspects of the operation of the survey, from data management to camera operation to science computing. It focuses on:

Data Management
Observing Systems
DECam Operations
Survey Strategy
Science Analysis Computing
Data Release

External Collaborations

We also collaborate with other scientists and projects to carry out joint studies including the Atacama Cosmology Telescope, VISTA Hemisphere Survey, the South Pole Telescope Survey, STRIDES, and others.

At each institution, a number of scientists share their knowledge of the cosmos and their perspectives on science with the general public. DES is committed to contributing to both our local communities and the global community.

DES welcomes new ideas for external collaboration – if you are interested, please contact one of the working group coordinators or analysis team leads listed above.
