Welcome to the 12th Complex Motion in Fluids Summer School, which will take place from Sunday 15th June 2025 to Friday 20th June 2025 on Oleron Island, along France's western coastline. The school is organised by LadHyX (CNRS & Ecole Polytechnque, F)  in collaboration with the University of Cambridge (UK), the University of Twente (NL), and the Technical University of Denmark (DK).

At the summer school, each invited lecturer will give a 90-minute lecture on a topic in fluid dynamics at an introductory level for PhD students and a 60-minute lecture on their current research.

Registration fees are fixed to 880€ VTA included and cover full-board accommodation for five nights starting on Sunday June 15th in the evening (housing in shared beach houses, full meal and extra-activities).

Pre-registration and abstract submissions are now closed. Applications are currently being reviewed and applicants will be notified by the end of March.

Accepted  participants will be contacted in a second step regarding the online payment in April of the registration fees.

A tentative program for the week can be found here.

The scientific program will include 9 sets of two lectures by our invited speakers, flash talk sessions where participants will present their work in short (2') presentation followed by a poster session, and ample talk for free discussions and relaxing time to enjoy the center's facility (pool, tennis courts, beach access, bike rentals). An outing to discover Oleron's island will be organised on Wednesday afternoon. 

The Summerschool will be held in the island resort "La Vieille Perrotine" located outside of Saint Pierre d'Oleron in France. Participants will be hosted in small bungalows with individual rooms and shared bathroom facilities. The ~40ha resort offers many facilities (swimming pool, tennis courts, bike rentals..) and a direct access to the beach. 

Oleron offers a secluded and peaceful setting for a week of fruitful exchanges, but is also quite remote. The largest city and transportation hub is La Rochelle which is well connected by train to Paris (high-speed connection, 3h-3h30, 5-6 direct connections daily) and Bordeaux (regional trains, 2h30). 

A bus shuttle to la Vieille Perrotine will be organised to bring participants from the La Rochelle train station  on Sunday afternoon (~4.30pm) and return on Friday afternoon to La Rochelle (3pm-3.30pm). You are strongly advised to plan your travel to La Rochelle according to meet these shuttles as reaching the center on your own might be difficult (public transportation is scarce to / on Oléron).

Participants are strongly recommended to travel to La Rochelle by train. Overseas participants flying to Paris and connecting to the train to La Rochelle should take into account ample transfer time from the airport to the Montparnasse  station in Paris (~1h from Orly (ORY) and >1h15 from Charles de Gaulle (CDG) by public transportation, recommended)
