We regret to announce that we have decided to cancel Summer School 2020 due to the COVID-19 pandemic. Uncertainty about the possibility of international travel and the unavailability of premises prevent us from meeting as planned in July. The next edition will therefore take place in 2021. Exact dates will be communicated at a later date. With your agreement, we will keep your contact details to inform you when registration opens. We wish you a beautiful and healthy summer. Best regards
