With more than 1000 registrations, the ESCAPE Summer School on Data Science for Astronomy, Astroparticle & Particle Physics held online from 7 to 18 June 2021 was a success.
This event was a continuation of the ASTERICS summer schools held at the LAPP in 2017, 2018 and 2019. Dedicated to the development of projects for astrophysics, astroparticle physics & particle physics, the school that was supposed to take place at Laboratory of Annecy of Particle Physics (LAPP) was moved to an online event, due to the current situation in France and the rest of the world. A different organisation but with the same goal: to provide any software engineer, data scientist or interested students with the tools and good practices to do data science in their field and in the context of open data and open science.
