Hari Balakrishnan: Architect of Connectivity and Innovation

In the realm of computer science and artificial intelligence, certain individuals stand as trailblazers, shaping the future through innovation and dedication.

One such luminary is Hari Balakrishnan, the Fujitsu Professor of Computer Science and Artificial Intelligence in the Department of Electrical Engineering and Computer Science at MIT. Beyond academia, he is also the Co-founder and CTO at Cambridge Mobile Telematics (CMT), a company at the forefront of revolutionizing mobile telematics worldwide.

Early Life and Academic Journey of Hari Balakrishnan

Balakrishnan’s journey began in Nagpur, India, where he was born and later raised in the vibrant cities of Bombay (Mumbai) and Chennai. His academic pursuits led him to the prestigious Indian Institute of Technology, Madras, where he earned his bachelor’s degree in computer science in 1993.

Following this, he ventured to the University of California, Berkeley, culminating in a doctoral degree in computer science in 1998. Since then, Balakrishnan has been an integral part of the MIT community, contributing significantly to the fields of computer science and artificial intelligence.

Pioneering Contributions in Computer Networks

Hari Balakrishnan’s impact on computer networks is profound. He co-invented the Chord distributed hash table, the RON resilient overlay network, and the rcc tool for verifiable Internet routing.

His work in Internet congestion control architecture includes groundbreaking innovations such as the Congestion Manager, the Congestion Control Plane, and the Fastpass system, contributing to the efficiency and reliability of data transport in data centres.

Mobile Sensing: Redefining Connectivity

The CarTel project, a collaborative effort between Hari Balakrishnan and Sam Madden, marked a paradigm shift in the realm of mobile sensing. Introducing the concept of using sensors attached to mobile assets, such as vehicles and phones, the project laid the foundation for advancements like the Pothole Patrol and VTrack algorithms.

The success of the CarTel project led to the formation of Cambridge Mobile Telematics, a global leader in mobile telematics, transforming the landscape of road safety.

Transformative Work in Cricket, Wireless Networks, and Internet Security

Between 1999 and 2004, Hari Balakrishnan’s work on the Cricket indoor location system showcased the fusion of radio and ultrasound for precise indoor location. His contributions to wireless networks, TCP Migrate protocol, spinal codes, and SoftPHY exemplify his multidimensional approach to network challenges.

Balakrishnan’s impact extends to Internet security, with contributions to the Infranet anti-censorship system and distributed quota enforcement for spam control. His router design work and proposals for layered naming architecture further underscore his commitment to fortifying the foundations of the Internet.

Recognitions and Accolades

Hari Balakrishnan’s illustrious career has garnered numerous accolades, including the ACM doctoral dissertation award, election as a Fellow of the Sloan Foundation, and MIT’s Harold E. Edgerton prize.

His election to the US National Academy of Engineering and the American Academy of Arts and Sciences, along with receiving the IEEE Koji Kobayashi Computers and Communications Award, showcases the depth of his contributions.

Impact Beyond Academia: Entrepreneurship and Industry Leadership

In 2010, Hari Balakrishnan co-founded Cambridge Mobile Telematics, serving as its Chairman. The company’s exponential growth, fueled by innovations from the CarTel project, attracted a $500 million investment from the SoftBank Vision Fund in 2018.

Balakrishnan’s role as an advisor to various companies, including YugabyteDB, Valtix, and StreamAlive, further emphasizes his influence in shaping the technological landscape.
