Sandatharaka, an artist born and raised in the village of Ampitigoda in the Maturata region within Sri Lanka's central mountains, profoundly integrates his lived experiences into his creative endeavors. His oeuvre, predominantly executed in oil paints and watercolors, is marked by an experimental approach that seeks to explore the intrinsic properties of these mediums.

His artistic practice is distinguished by a dual focus: the pursuit of aesthetic refinement in the final finish of his works and the articulation of a potent visual language that reflects the strength of the artist's personal expression.

He has also been working on a studio-based practice for a very long time, and his research is integrated with a broad education in traditional academic art. In his continuous experimentation, Sandatharaka maintains a rigorous adherence to the inherent qualities of his chosen mediums, thereby achieving a balance between innovation and tradition.

Additionally, his reputation as an arts educator is well-established, with his pedagogical approach being profoundly shaped by the extensive practical experience he has amassed over his long-standing career in the field.
