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).

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).

The final program for the week can be found here.

The scientific program will include 9 sets of two lectures by our invited speakers.

All participants will  present a flash talk to present their work in short (2') presentations on Monday and Tuesday evenings, and will have the opportunity to present a poster on one of the following poster sessions during one of the coffee breaks.

The schedule and list of flash talks & posters can be found here.

Additionnally there will be ample free time for 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). 

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)

Bus shuttles to la Vieille Perrotine are organised to bring participants from the La Rochelle train station  on Sunday afternoon and return on Friday afternoon to La Rochelle. You are strongly advised to plan your travel to La Rochelle accordingly to meet these shuttles as reaching the center on your own might be difficult (public transportation is scarce to / on Oléron).

On Sunday June 15th, two different shuttles are organised  from La Rochelle train station:

• Shuttle #1 will depart from the train station at 4.45pm
• Shuttle #2 will depart from the train station at 6.45pm (participants on this shuttle will need to proceed directly to the restaurant for dinner before checking into their rooms)

The list of participants assigned to each bus is available here.

On Friday June 201th, one shuttle will be organised from Oleron, leaving after lunch to arrive at the station around 3.30pm.

The meeting point with the shuttle is located next to the station, but on the opposite side to the main entrance (see the map below):
