A Sri Lankan by origin, Senaka attained fame early in life as a prodigy for his works of art. He held his first international solo exhibition at the age of ten, in New York. Although he painted copiously and held many shows both in his native country as well as abroad, it was only after he went to Yale school for graduation in Art and Architecture did he realize that his true calling lay in the field of art. For the past decade, Senanayake has concentrated his art as a medium for environmental advocacy: depicting beautiful scenes from the rainforest to promote public awareness of environmental degradation in his native Sri Lanka and around the world. Senanayake's work shows a fervent passion for nature's beauty and a great knowledge of the flora and fauna of the rainforest. His work has been shown at most parts of Europe and South Asia with critical acclaim. Till date he has more than 100 solo shows to his credit, and numerous group shows in the countries of Europe, China, Australia, Japan, Singapore, Czechoslovakia, Korea and Egypt to name a few. His work has been documented by Metro Goldwyn, British Movietone News, BBC TV, London, Yeo Soo TV, South Korea, TV Austria, and Star TV, India. Various journals, magazines and newspapers such as The New York Sunday Times, Washington Post, London Times, Weser Kurier, Germany, UNESCO Features, Paris, National Geographic Magazine, Asia Week and many others, have devoted their mediums to document Senaka’s work.
