# F. Thomson Leighton

Frank Thomson "Tom" Leighton (born 1956) is an American mathematician who is the CEO of Akamai Technologies, the company he co-founded with Daniel Lewin in 1998, and a professor of applied mathematics at the Massachusetts Institute of Technology (MIT). He is a member of the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT.

## Early life and education

Leighton's father was a U.S. Navy colleague and friend of Admiral Hyman G. Rickover, the father of naval nuclear propulsion and a founder of the Research Science Institute (RSI). His brother, David T. Leighton, is a professor at the University of Notre Dame specializing in transport phenomena.
He received his B.S.E. in electrical engineering from Princeton University in 1978, and his Ph.D. in mathematics from MIT in 1981.

## Career

Leighton discovered a solution to free up web congestion using applied mathematics and distributed computing.
Leighton worked on algorithms for network applications and has published over 100 papers on algorithms, cryptography, parallel architectures, distributed computing, combinatorial optimization, and graph theory. He also holds patents involving content delivery, Internet protocols, algorithms for networks, cryptography, and digital rights management.
Leighton has the Presidential Informational Technology Advisory Committee (PITAC) and chaired its subcommittee on cybersecurity. He is on the board of trustees of the Society for Science & the Public (SSP) and of the Center for Excellence in Education (CEE), and he has participated in the Distinguished Lecture Series at CEE's flagship program for high school students, the Research Science Institute (RSI).
