Born in 1977, Lek Kiatsirikajorn studied painting at Silpakorn University in Bangkok before switching to photography, which interested him with its potential for outreach. He was promising young artist on the Thai scene in 2001 when he decided to move to England and study photography at The Arts Institute at Bournemouth. Immediately after graduating, he won a photography competition called ”Fashion Meets Art”. It was organised by ArtReview, a British art magazine. He returned to Thailand in 2008 after spending several years studying and working in the UK.

During his last two years in England, he became fascinated with great American documentary photographers such as Walker Evens, Stephen Shore, Joel Sternfeld and Alec Soth. The way they managed to project a strong visual documentation of American society through a personal vision inspired him to look back to his own roots. Lek has been working commercially, as well as working on his personal photography projects since he came back.
He has also been exhibiting internationally.
