Nokia Bell Labs has appointed Guru Parulkar as the new Head of Bell Labs Research, placing a veteran networking researcher and entrepreneur in charge of the company’s long-term research agenda spanning AI, networking, cloud, and edge computing. The announcement comes as Nokia consolidates Bell Labs Core Research and Bell Labs Solutions Research into a single organization focused on advancing technologies for the AI era.
Parulkar brings decades of experience from academia, government-backed research initiatives, industry consortia, and startups. His career includes leadership roles at Stanford University, the Open Networking Foundation (ONF), Intel, and multiple DARPA-supported research programs. He has worked across several major technology transitions, including software-defined networking (SDN), cloud-scale infrastructure, edge computing, and AI-enabled systems.
The leadership change also marks the upcoming retirement of Peter Vetter, who has led Bell Labs Core Research for nearly two decades. Vetter is scheduled to retire on July 17, concluding a tenure that helped guide Bell Labs research activities across optical networking, communications systems, and advanced technology development. Nokia said the combined Bell Labs organization will create a unified focus on science and technology research supporting future AI-driven connectivity platforms.
