Sirachai (Shin) Arunrugstichai (b. 1987) is a Thai conservation photographer, specialising in marine conservation issues. Shin originally picked up photography to document marine biodiversity, while working as a field biologist. However, after realising the power of photography for communicating serious conservation issues with the public, Sirachai later shifted his career path toward photojournalism in 2015.
Currently, Shin is a freelance photographer for National Geographic Magazine (Thai edition), starting with his work on the plight of sharks in Thai waters in 2016. He later covered three additional stories for the magazine, the degradation of the Andaman sea in 2016, the development of a large-scale deepwater port in Southern Thailand in 2017, and the Marine Protected Areas (MPAs) of Thailand in 2018. As freelancer, he has also been working on assignment with several conservation organizations, including IUCN Asia, Save Our Seas Foundation, WildAid and more, while some of his works have been published in National Geographic, the Washington Post, the Guardian and BBC Earth.

      He has received a number of awards in major international competitions and gave a talk for TEDx Bangkok in 2017 on the topic of conservation photography. Since 2017, Shin has joined the International League of Conservation Photographers as an Emerging League Photographer and has also been selected as one of the six talents from Southeast Asia and Oceania region of the 6x6 Global Talent Program by World Press Photo Foundation. 
In 2019, Shin has been selected as one of the PDN’s 30 New and Emerging Photographers to Watch by Photo District News and received the Early Career Explorer Grant from National Geographic Society.


      Although his focus is in photojournalism, he is still active within the scientific community, working on conservation biology of sharks in Thailand and he is willing to assist on any shark researches or conservation projects in the Andaman Sea region.

      Shin is currently based in Bangkok, so without going out in the field to cover conservation stories, he does not know much what to do with his life in the big city.
