Chowdhury moved to Delhi in 1972 as the curator of the art collection at Rashtrapati Bhawan. In 1975, he along with some leading Delhi artists founded Gallery 26 and Artists' Forum. From 1976, onwards, Chowdhury participated in several exhibitions and art camps abroad. He published ajoumal called Art Today in 1981 with Shuvaprasanna. In 1987, Chowdhury joined Kala Bhavan, Santiniketan as professor of painting. Besides his numerous activities, Chowdhury has written extensively on contemporary art.

Always a powerful artist, Chowdhury developed his individual style after his return from France in the late '60s. Although Chowdhury has painted oils, his forte is painting in ink, water colour and pastel. The sinuous line contouring the flaccid figures, the crosshatching to achieve tonal variations distinguish C'howdhury's paintings which show men and women m enigmatic situations with provocative gestures placed in a dark dream- space. There is a bit of the theatre of the absurd. Chowdhury lives and works in Sandniketan.
