Dian is a multi-award winning fine art wildlife photographer, scientist, author, inspirational speaker and world records discoverer, specialised in world record and world class individuals in iconic megafauna species.
 He creates timeless images by using an immersive approach, portraying as never seen before giants that have captured our imagination. He pays much attention not only to the subject selection, perspective and composition, but also to body postures. The artistic question he asked himself is: “if a Statue, a Monument were to be raised to a species, what would that look like?” He was a member of the jury of the Golden Turtle Photography Awards (2023) and the Jackson Wild Film Festival (2022) and the curator of the exhibition Europe's Wild Heart (Brussels, 2019). Dian has 10 years of artistic, scientific and conservation experience working with big-tusked African and Asian elephants. About 30 of his images with big-tusked elephants were awarded in prestigious photography competitions such as GDT European Wildlife Photographer of the Year, MontPhoto, Refocus Awards, MonoVisions Awards, Monochromatic Awards, HIPA Diversity, Px3 Paris, Fine Art Photography Awards, Nature Photographer of the Year or Africa Geographic Photographer of the Year. In addition, Dian won Photographer of the Year: Wildlife in the Re-Focus Awards 2024, he was a First Prize Winner (Montier, 2020) and Grand Prize Winner (Untamed, 2018).

Dian is an accomplished speaker on biodiversity and environmental issues at events in Africa, Asia, Europe and North America.
