The Cosmostatistics Initiative (COIN) is a worldwide endeavor aimed to create an interdisciplinary community around data-driven problems in Astronomy.

It was designed to promote innovation in all aspects of academic scientific research.

The group is lead by Rafael S. de Souza (University of North Carolina at Chapel Hill, USA), and co-chaired by Emille E. O. Ishida (Universite Clermont Auvergne, France), Alberto Krone-Martins (Universidade de Lisboa, Portugal),  Ewan Cameron (Oxford University, UK) and Jessi Cisewski (Yale University, USA).

Researchers willing to join are welcome to contact any of the chairs!


An unstructured and intimate meeting, offering opportunities for collaborative research, learning, and sharing of expertise with concrete scientific outcomes.

The main goal of the CRPs is to benefit young and experienced researchers in astronomy, statistics, computer science and related disciplines alike. Thus contributing to the establishment of Astrostatistics and Astroinformatics as full-fledged disciplines.

We also aim at creating a personal bond among our members, providing a completely informal environment where such intimate connections can grow.

Thus, the program is held in a residence and participants share not only scientific discussions, but participate in logistic decisions during the program.

A complete report of of previous editions and results can be found in the Residence Programs and Projects sections, respectively.
