Infosys co-founder Nandan Nilekani has donated Rs 315 crore to his alma mater Indian Institute of Technology (IIT) Bombay to celebrate 50 years of his association with the institution.

Nilekani had joined the institute in 1973 for a Bachelor’s degree in electrical engineering.

“The donation is intended to foster world-class infrastructure, stimulate research in emerging areas of engineering and technology, and nurture a deep tech startup ecosystem at IIT Bombay,” according to a press statement.

The contribution stands as one of the largest donations made by an alumnus in India, the IIT statement added. He had earlier contributed Rs 85 crore to the institute, which now takes his total contribution to Rs 400 crore.

“IIT-Bombay has been a cornerstone in my life, shaping my formative years and laying the foundation for my journey. As I celebrate 50 years of my association with this esteemed Institution, I am grateful to give forward and contribute to its future,” the press release cited Nilekani as saying.
