After passing out from Art College, Partha devoted his entire life to art under the tutelage of Ashesh Mitra. To aid his art works, Partha had worked as a tuition teacher, a railway porter, and painted garages.
In the early 80’s, along with a colleague, Partha wanted to venture into Film Publicity. But an encounter with the legendary Satyajit Ray, the Indian film director put him back in art.
Partha joined as an art teacher in DPS, Angul, Orissa and later Kendriya Vidyalaya, Dhanbad. He continued painting under the guidance of Ashesh Mitra. He became a member of the renowned Reflection group of Calcutta in the 1980s. His first exhibition as part of the reflection group was in 1988.
It was during this time, Partha started receiving commissioned works. His work included copies of Renaissance painters like Rembrandt, Renoir, Vermeer, Titian. The commissioned works financed his personal series as a painter.
