Ari Juels is a prominent computer scientist and an influential figure in the fields of computer security, cryptography, and blockchain technology. He currently holds the prestigious position of Weill Family Foundation and Joan and Sanford I. Weill Professor of Computer Science at Cornell Tech, part of the Cornell Ann S. Bowers College of Computing and Information Science, and the Jacobs Technion-Cornell Institute. In addition to his academic roles, Juels serves as the chief scientist at Chainlink Labs and is a co-director of the Initiative for CryptoCurrencies and Contracts (IC3), an initiative focused on research and educational activities in cryptocurrencies and smart contracts. ^{[2] [1]}

Education

Juels studied at Amherst College from 1987 to 1991, earning a Bachelor of Arts degree in classical Latin literature and mathematics. He later completed a Ph.D. in computer science at the University of California, Berkeley in 1996. His academic training in mathematics and computer science provided the foundation for his subsequent work in cryptography, cybersecurity, and digital systems research. ^{[2] [3]}

Career

Before joining the academic field, Juels was deeply involved in industry-based research. He served as the chief scientist at RSA Security, a globally recognized leader in cybersecurity. At RSA, he was also the director of RSA Laboratories, the research arm of the company where he made significant contributions to the development of security technologies. Furthermore, Juels held the role of a distinguished engineer at EMC (now known as Dell EMC) until 2013, playing a pivotal role in guiding the company’s technology strategies and innovations. In his academic role, Juels has been instrumental in advancing the study of cryptography and blockchain through teaching and directing research initiatives. Since joining Cornell, he has co-founded and co-directs the Initiative for CryptoCurrencies and Contracts (IC3), which plays an essential role in exploring the capabilities and applications of blockchain technology. IC3 collaborates with academic institutions, government organizations, and industry players to conduct cutting-edge research in cryptocurrencies, smart contracts, and related areas. ^{[1] [2] [3]}
