Nisha is a social entrepreneur, founder & director of ArtsEkta - one of the only organisations on the island of Ireland promoting ethnic arts, culture and heritage. She founded this organisation in 2006 following two decades of experience in the arts and after discovering a critical gap for quality ethnic arts engagement in the sector. Nisha was former member of the executive board of the Arts Council of Northern Ireland by appointment from the Minister for Communities, and is also a member of the Intercultural Arts Steering Group which oversees the implementation of the Intercultural Arts Strategy developed by the Arts Council of Northern Ireland.

In June 2014, Nisha was the first Asian women from Northern Ireland to be awarded the prestigious UK Asian Women of Achievement Award for contribution to arts and culture, and later that month was awarded an OBE for services to the minority ethnic sector in the 2014 Queen's Honours List.
