A graduate of the Purnea Art College in Bihar, Dewashish Das's interest in art can be traced as early as school. Dewashish worked with the eminent artist Shri Sukumay Mitra, a graduate from Shantiniketan and student of Nandalal Bose, after a stint at the Rabindra Bharati University in Kolkata. A recurring theme of culture and heritage is most commonly seen in Dewashish's paintings. Das has participated in several regional, national and international exhibitions.
