Gatien Cosendey

Gatien started his underwater journey in 2013 with a try dive in Bora Bora and took his Open Water Diver course later that year in the cold and dark waters of Lake Leman, Switzerland. He demonstrated an early interest for overhead environments, enjoying ice diving and then cave diving.
The willingness to share his passion with others brought him to take a first instructor class and shortly after a DSLR camera underwater. Since then, he continuously worked on sharpening his teaching and photography skills: they both are efficient tools to enable people to discover the marvelous underwater world.
He is often seen in his yellow SF-Tech dry suit diving Swiss lakes and caves, and enjoy diving caves, mines and wrecks across Europe.
Besides diving, Gatien holds a Master’s degree in Physics and a PhD in Photonics from the École Polytechnique Fédérale de Lausanne and works as an optical engineer in the field of augmented and mixed reality.
