Bhowmick, who guided Churchill Brothers to I-League title last season has taken over the reigns from Sukhwinder Singh, who resigned on October 14, following the team's poor performance in the ongoing I-League.
The one-year deal was signed on Thursday.
Bhowmick took charge of the team before the Pune FC match, which they went down fighting 1-0 in Pune on October 19.
He is looking forward for a change in the team's fortune and is hoping for their first win when they play against United Sports Club in their away match on November 2.
