At MIT in the mid-1990s, Professor Anantha Chandrakasan began working on energy-efficient electronic circuits, and later on chips, a field of study that has been of great help to today’s smartphones. The focus of his work has been to develop technology for energy-starved sectors. Now, this alumnus of University of California, Berkeley, who migrated to the US in his teens and did his Bachelor’s, Master’s and doctorate in electrical engineering, heads the biggest department at MIT, the engineering school. Within the institute, he is regarded highly for being people-centric and innovative. He also helps current students connect with old ones in academia and industry. It is not for nothing that the brilliant researcher has taken up a teaching post—he believes that theory and application are intertwined and exhorts his undergraduate students to come up with publication-worthy research. For an academic of such accomplishments, Chandrakasan is down-to-earth and humble. The Chennai-born engineering hotshot hopes to continue his work on energy-efficient systems.
