Ganapathi is a most jovial person and a smart working guy; he never-give-up anytime, even though it is beyond his capability. He is a key team player, can handle pressurized situations with a smile, and encourages others to complete the task within the time frame. He is known as Kattappa on the IIT Campus because of his dedication and hairstyle. He was one of the fine candidates with an eight-pack body in the campus sports. He is pursuing his Ph.D. in Energy conversion and storage in electrochemistry under Prof. Kothandaraman R. He attended more than 10 National and International conferences in India, Singapore, and Switzerland. He received several awards such as the Institute Research award, ACS Best poster award, and many more. He is passionate about research in energy and wants to become an entrepreneur in the same field.
