As far back as Delphin could remember, the romantic concept of an unspoiled wilderness has tinted his first look on nature, and has influenced his academic education as well as the various projects in which he has been involved since. Some figures clearly stir up his dreams and provided a momentum to them. The Swiss artist and philospher Robert Hainard was probably the most omnipresent of all. Other sources, like the Arseniev's memoirs picturing Dersou Ouzala, Shackleton's adventures or Edward O. Wilson's essays have all influenced in one way or another Delphin's approach to nature.

Delphin is a wildlife biologist. In our modern world, science and conservation provide him opportunities to stay connected to nature, to improve his understanding of it and to contribute to its preservation. Delphin has worked in various environments, from East Africa to the Hawaiian islands, or from Northern Quebec to Antarctica where he spent 14 months on a scientific station studying wildlife at age 21. In 2004, he completed a Master degree in wildlife biology at the Université du Québec, which ended a three-year experience in Canada. He then moved to the USA and got involved in various conservation projects in California, the Caribbeans, the Hawaiian Islands and throughout the Pacific Northwest. In 2005, while lecturing at the University of California Los Angeles, he initiated a long-term project aiming at promoting the conservation of the Bale Mountains, in the Ethiopian Highlands. Late 2008 Delphin moved back to France, where he works as a consultant.

Delphin is a member of the International League of Conservation Photographers.
