Juniper Networks on Wednesday announced it has hired Shaygan Kheradpir to be its chief executive officer, effective January 1, 2014. Kheradpir succeeds Kevin Johnson, who in July announced his plan to retire as CEO. Johnson will remain as a member of the board.

"The board has conducted a comprehensive search process and we're very excited to name Shaygan Kheradpir as our next chief executive officer," said Scott Kriens, chairman of the board, Juniper Networks, which is based in Sunnyvale, Calif. "Shaygan has a proven track record of successful business operations and technology leadership, with industry knowledge and technical vision from the perspectives of both telecommunications service providers and global enterprises. Most importantly, Shaygan's values and vision for the company align very tightly with our own, building a strong foundation for Juniper's future."

Kheradpir joins Juniper Networks from Barclays PLC, where he served as the chief operations and technology officer and as a member of its executive committee. Prior to joining Barclays, he was executive vice president and chief information and technology officer at Verizon Communications.

"Juniper Networks delivers innovations that are transforming the way people interact, conduct business, and connect as a global community," said Kheradpir in a press release. "I am honored to lead this visionary organization and look forward to working with this group of dedicated and talented professionals to drive the next phase of the company's growth."

Kheradpir joined Barclays, a major global financial services provider, in 2011. While responsible for its operations and technology, he helped lead customer-focused innovation projects.

Kheradpir was an original member of the management team when Verizon was created, and helped Verizon transition from a regional telephone company to a broadband, media and global communications leader. During his tenure, he helped to create and implement technologies and such as IP multi-media and Fiber Optic Service (FiOS).

Kheradpir holds a bachelor's, master's, and Ph.D. in electrical engineering from Cornell University.
