Nipa asserts her commitment to fight social injustice and promote gender equality through her professional work as a development communication expert in the audiovisual media. Her film Children in the Hidden World (2005) zooms in on the lives and future of daughters of sex workers living in the red-light areas in Bangladesh. It also elaborates the circle a young girl, born into brothels, goes through to become a sex worker. Apart from a few professional actors, sex workers of Doulotdia and their children have enacted their reality in the film.

"While working for ATN Bangla's Amra Korbo Jai (a weekly news-based show for adolescents), I got the chance to be acquainted with a number of children from the red light areas in Tangail. They were very talented -- good in singing, dancing and attentive to their studies. Yet, their lives are different from other children. I was interested to get an insight of their world," Nipa explains the background of the film. With the cooperation of local NGOs, she conducted the necessary research activities on Doulotdia brothel, for the film.

From birth to growing up, education, crises and surroundings aspects of the life of a girl child born into a brothel, are depicted with utmost empathy in the film, featuring interviews interspersed with dramatised sequences. Actors Tamalika Karkakar and Mithu have enacted the roles along with the sex workers of Doulotdia in the film.

Another noteworthy film by Nipa was a series of five documentaries on street children in Dhaka. Chena Mukh Ochena Chobi focused on the unheard stories of street children -- addicted to drugs, taken to prostitution, begging, selling flowers -- and the usual tokai. The film reveals that hundreds of street children in Karwan Bazar are engaged in substance abuse. Nipa explores the reason behind their addiction, their background and their likely future, in the documentaries.

According to the filmmaker, "A major issue in making films like these is shortage of funds. As these films lack glamour and commercial viability, they don't have much market value."

Nipa was the director and scriptwriter of the TV programme Amrao Pari, aired on ATN Bangla. The show went on to win an Emmy Award in the UNICEF/ICDB category in 2004. The filmmaker has also received the International Meena Media Award in 2005 and Anannya Top Ten Achievers in 2004.

At present Nipa is working on a drama serial based on Thakur Mar Jhuli, a hugely popular collection of fairy tales by Dakshinaranjan Mitra Majumder.
