Subhash Kak is Regents Professor of Computer Science Department at Oklahoma State University in Stillwater.

Born in Srinagar, Kashmir, Kak was educated in various places in Jammu and Kashmir. He completed his PhD in Electrical Engineering from Indian Institute of Technology, Delhi. During 1975-1976, he was a visiting faculty at Imperial College, London, and a guest researcher at Bell Laboratories, Murray Hill. In 1977, he was a visiting researcher at Tata Institute of Fundamental Research, Bombay. During 1979-2007, he was with Louisiana State University, Baton Rouge where he served as Donald C. and Elaine T. Delaune Distinguished Professor of Electrical and Computer Engineering.

Kak’s research has spanned the fields of information theory, cryptography, neural networks, and quantum information. He is the inventor of a family of instantaneously trained neural networks (for which he received a patent) for which a variety of artificial intelligence applications have been found. He has argued that brain function is associated with three kinds of language: associative, reorganizational, and quantum.

Kak was the first to look for information metric for a quantum state over thirty years ago. His work on quantum information includes the only all-quantum protocol for public-key cryptography. He has written on the limitations on the capabilities of quantum computers and proposed a new measure of information for quantum systems. This work as well as his proposed resolution of the twin paradox of relativity theory have received considerable attention in the popular press.

Kak is also an archaeoastronomer and Vedic scholar. His discovery of a long-forgotten astronomy of ancient India that has been called “revolutionary” and “epoch-making” by scholars. In 2008-2009, he was appointed one of the principal editors for the ICOMOS project of UNESCO for identification of world heritage sites. He is the author of 12 books which include “The Nature of Physical Reality,” “The Architecture of Knowledge,” and “Mind and Self.” He is also the author of 6 books of verse. The distinguished Indian scholar Govind Chandra Pande compared his poetry to that of William Wordsworth.
