A nu Aga is an Indian billionaire businesswoman and social worker who led the energy and environmental engineering company Thermax for many years. She took over as chairwoman of the company in 1996 following the sudden death of her husband, Rohinton Aga. Her tenure began under tragic and challenging circumstances, as she had also lost her son just a year earlier. Despite these personal hardships, she steered the company through a difficult period and led its successful turnaround.

Under her leadership, Thermax streamlined its operations, shed unprofitable ventures, and focused on its core business of providing energy and environmental solutions. She retired as chairwoman in 2004, handing over the reins to her daughter, Meher Pudumjee. Since her retirement, Anu Aga has dedicated her life to social work and philanthropy, with a strong focus on education. She was nominated to the Rajya Sabha, the upper house of the Indian Parliament, in 2012 in recognition of her contributions to social work.
