Joshi was born in 1934 in Ranchi, Bihar . Her parents were from Nepal and her father was an officer of the British Army until the nation’s independence in 1947. Although the family was Hindu, she was educated by Christian missionaries in Patna. At that time she learned of Mother Teresa’s work and wanted to share in that service. She soon converted to Roman Catholicism and joined the Missionaries of Charity, founded by Mother Teresa.

Joshi earned a Master’s degree in Political Science from an Indian university and received additional training as a lawyer. She was one of the first Sisters of the institute to head a foreign mission when she went to Panama.

In 1976, Joshi started the contemplative branch of the Missionaries of Charity and remained at its head until 1997 when she was elected to succeed Mother Teresa as Superior General of the institute.

The government of India bestowed the Padma Vibhushan, the second highest civilian award, on Sister Nirmala on Republic Day (January 26) 2009 for her services to the nation. Her term as Superior General ended on 25 March 2009, and she was succeeded by German-born Sister Mary Prema Pierick, M.C
Sister Nirmala died on June 23, 2015 in Kolkata.
