Ronjon Nag Inventions Information

Ronjon Nag is a British-American inventor and entrepreneur specializing in the field of mobile technology. He co-founded the technology company Lexicus, acquired by Motorola in 1993 and Cellmania, acquired by Research in Motion in 2010. He later served as Vice-President of both Motorola and BlackBerry.

Ronjon Nag received his bachelor's degree in 1984 from the University of Birmingham, where he studied Electronic and Electrical Engineering. He received a Master of Science degree from MIT in Management Science and studied neural networks in Stanford University's Department of Psychology. After completing a Doctorate in Engineering at Cambridge University, he studied as a Harkness Fellow in the United States at Massachusetts Institute of Technology and Stanford University. He has since become a fellow of the Stanford University Distinguished Careers Institute and a Fellow of the Institution of Engineering and Technology.

Nag is currently the Chairman of Embee Mobile, a company enabling market research on mobile devices, anda co-founder of Payplant, an alternative finance platform. He also serves as chairman at Ersatz Labs, which specializes in machine learning. Nag serves on the boards of Bounce Imaging, which develops tactical cameras for the defense and security industry, as well as Introhive, which creates sales automation software.

He divides his time between Cambridge in the United Kingdom and Silicon Valley in California.

Nag's work has focused on inventing new systems for interacting with mobile devices, resulting in breakthroughs in the application of speech recognition, handwriting recognition, predictive text and touch screens for mobile devices. As a student at Cambridge University, Nag wrote an article applying a hidden Markov model to speech recognition, which became the basis for his Phd on the subject. In 1991 Ronjon Nag began researching artificial neural networks, first under Amar Gupta at MIT and then in Stanford University's Department of Psychology, studying under David Rumelhart. In 1992, Nag co-founded the technology company Lexicus in Palo Alto, California. As CEO and as a computer scientist, Nag oversaw the emergence of Lexicus as an industry pioneer of speech and predictive technology systems and saw the acquisition of Lexicus by Motorola in November 1993. As a subsidiary of Motorola, Lexicus introduced some of the first devices with Chinese handwriting and speech recognition. In 1999, he founded Cellmania, a mobile infrastructure company that provided digital rights management for mobile content, enabling the creation of some of the first mobile app stores. Cellmania was sold to Research in Motion, now BlackBerry Limited, in 2010 for an undisclosed sum.

In 2014 Nag was the recipient of the Mountbatten Medal awarded by the Institution of Engineering and Technology. The award cited Nag's influence on the creation of the modern mobile phone industry with the development of smartphone components such as text and speech recognition and digital distribution platforms, technologies that were later incorporated widely into early smartphones developed by Motorola and BlackBerry.
