ARCS® Foundation is proud to announce Albert G. Greenberg, PhD, as the 2026 ARCS Alumni Hall of Fame Inductee, recognizing a career that has helped shape the digital infrastructure powering today’s Internet, cloud computing, and artificial intelligence.

Hall of Fame Inductees are ARCS Scholar Alumni whose work has made an extraordinary impact on science, innovation, and US competitiveness. Greenberg is a pioneering computer scientist whose research, innovation, and engineering leadership have helped shape the foundational infrastructure of the modern digital world. His breakthroughs underpin today’s high-scale Internet backbones, cloud computing platforms, and next-generation AI infrastructure. His work has enabled reliable, high-performance networking systems that support global commerce, large-scale scientific collaboration, and modern communications across continents.

As an engineering leader, Greenberg has played a critical role in advancing technology at AT&T, Microsoft, and with Uber currently, with impact spanning networking, computing, data systems, artificial intelligence, security, and high-scale services. His innovations helped transform cloud computing into the secure, affordable, and dependable global infrastructure that powers modern IT. Today, in the cloud-enabled AI era, his work continues to pave the way for secure and efficient AI computing platforms and the large-scale data systems that accelerate autonomous vehicle technology.

“One of the most satisfying moments in my career was seeing the very first bit successfully travel across a virtualized network in the lab,” Greenberg shares. “That technology is now used everywhere. When something you build stands the test of time, that’s incredibly rewarding.”

Greenberg’s achievements are notable for their rare combination of deep theoretical insight and real-world application. His innovations in software-defined networking and high-performance data and control planes fundamentally changed how networks are built, programmed, and scaled—making today’s cloud and AI ecosystems possible.

In recognition of his contributions to operating large carrier and data-center networks, Greenberg was elected to the National Academy of Engineering in 2016 and has received nearly all major ACM and IEEE awards in networking.

An ARCS Scholar in 1983 while pursuing his PhD in computer science at the University of Washington, Greenberg credits ARCS Foundation with providing both critical resources and an invaluable boost of confidence early in his career. “With my ARCS award, I bought the best modem I could find,” he recalls. “It allowed me to work faster and stay connected to my research, but just as important was the confidence boost. Knowing someone believed in my potential made a tremendous difference.”

Beyond his technical accomplishments, Dr. Greenberg is deeply committed to mentorship. Throughout his career, he has mentored hundreds of students and interns and has been a strong advocate for increasing diversity and inclusion within engineering and technology fields.

“Dr. Greenberg’s career exemplifies what ARCS stands for,” says ARCS Foundation National President Jill Bray. “His achievements show how investing in outstanding young scientists leads to innovations that benefit society and strengthen US leadership in science and technology.”

ARCS Foundation is honored to celebrate Greenberg as the 2026 Alumni Hall of Fame Inductee and to recognize the lasting impact of a career dedicated to solving complex problems that shape our connected world.
