Biologist turned photographer, Chien began his career in northern California as an environmental educator prior to moving to Malaysian Borneo in 1996 where he has been based ever since. Having acquired an incurable fascination for the rainforest, he now travels at least eight months every year to document tropical biodiversity, undertaking photographic assignments and leading field trips from Madagascar to Indonesia and New Guinea. Chien is a firm believer in the power of imagery to bring about change, and aims to use his work to inspire a deeper understanding and appreciation of the natural world with the hope of leading more people to take an active role in conservation.
