Researcher

Jonathan Turner

Jonathan Turner is a computer scientist whose scalable packet-switching work connects to AI through the network infrastructure used to move data among computing systems. He earned degrees at Washington University, Oberlin and Northwestern, joined WashU as a computer science professor in 1983, and published a 1986 paper on an integrated network for data, video and voice. At WashU, he co-founded the Applied Research Laboratory, directed it through 2012 and co-founded Growth Networks; he became an ACM Fellow in 2001 and a National Academy of Engineering member in 2007. As of October 2026, he is a Senior Professor at WashU and continues selected research projects.

Timeline

  1. 1977–1982

    WashU, Oberlin and Northwestern degrees

    He earns B.S. degrees in computer science and electrical engineering at Washington University and a B.A. from Oberlin College in 1977. At Northwestern, he earns an M.S. in computer science in 1979 and a Ph.D. in 1982.

  2. 1981–1983

    Bell Labs packet switching

    From 1981 to 1983, he serves as principal system architect for Bell Labs' Fast Packet Switching project.

  3. 1983–1997

    A WashU professorship

    He joins Washington University as an assistant professor of computer science in 1983, becomes a full professor by 1990, and chairs the Computer Science department from 1992 to 1997.

  4. 1986

    New Directions in Communications

    In 1986, he publishes “New Directions in Communications,” proposing an integrated network architecture for data, video and voice. His scalable packet-switch designs connect to AI at the network-infrastructure layer that moves data between computing systems.

  5. 1988–2012

    The Applied Research Laboratory

    In 1988, he founds the Advanced Networking Group and co-founds the Applied Research Laboratory at Washington University with Jerome R. Cox and Guru Parulkar; he directs the lab through 2012. Their Growth Networks startup develops high-performance switching components for Internet routers, and Cisco Systems acquires it in 2000.

  6. 2001

    An ACM Fellowship

    In 2001, ACM names him a Fellow for his design of scalable packet switches and contributions to an integrated packet network for data, voice and video.

  7. 2007

    National Academy membership

    He is elected to the National Academy of Engineering in 2007 for contributions to the design and analysis of high-performance communication networks.

  8. As of October 2026

    Senior professor at WashU

    As of October 2026, he is a Senior Professor in Washington University's Department of Computer Science and Engineering and continues selected research projects.

  1. 23% of people shaping AI who left a university for a company later returned to a universityIncludes Jonathan Turner. We estimate that 468 of the 2,011 people shaping AI who left a university for a company (23%) later returned to a university after a median of 5 years, and 163 of 829 (20%) made the reverse round trip.
  2. Universities keep AI researchers for a median of 6 years, compared with 2 years at frontier labsIncludes AT&T. Across 15,811 dated work stays (6,529 people), median role tenure runs from 6 years at universities to 2 years at frontier labs. We compare all five organization types, starting decades from the 1970s to the 2020s, and the organizations that keep people longest.
  3. 20% of people at companies who shape AI also hold a university role, led by Google and Stanford UniversityIncludes AT&T. We estimate that 539 of the 6,766 people with a known current organization (8%) hold both a university role and a company role, including 20% of people at companies and 13% of people at universities.
  4. People shaping AI work at a median of 3 organizations over a career: 3 for university starters and institute and lab starters, versus 2 for company startersIncludes AT&T. Across 6,853 people shaping AI with a dated work role, we estimate a median of 3 parent organizations over a career (mean 3.6), comparing role groups, starting sectors and starting decades from the 1950s to 2020–2026.
