Born in the Sri Lankan coastal village of Galle, Prasanna studied Fine Arts at the University of Kelaniya in Colombo, once known as the 'garden city of the east' and now the most populated city in Sri Lanka, before pursuing a career in advertising while continuing to paint.
One of few abstract painters in Sri Lanka, Prasanna first presented his acrylic works at the Kala Pola Art Market in Colombo in 2004. What followed was the development of the painter's first series 'Unknown Birds' (2009–2013)—bright outlines of scattered feathers emulating blurred avian forms mid-flight.
