Ron Nersesian, who heads Agilent Technologies' Sonoma County division, was promoted Thursday to the No. 2 spot at the $6.6 billion high-tech manufacturer.
Nersesian, 52, was named chief operating officer at Agilent, giving him day-to-day responsibility for its three business units: chemical analysis, life sciences and the Santa Rosa-based Electronic Measurement Group.
"Ron has done a superb job of leading Agilent's electronic measurement business," Agilent president and CEO Bill Sullivan said in a statement. "He was responsible for a complete transformation of EMG, resulting in outstanding profitable growth in current as well as emerging markets."
Santa Clara-based Agilent reported its best year in history on Tuesday. Much of its growth is being driven by demand for next-generation smartphones.
To replace Nersesian, Agilent tapped Guy S??to lead the electronic measurement division. S?? 56, has been vice president of the company's microwave and communications business since 2009.
Nersesian joined Hewlett-Packard in 1984 two years after graduating from Lehigh University and went to Agilent when it was spun off from H-P in 1999. He held various management posts over the last three decades, coming to Santa Rosa in 2005 as vice president of its wireless unit.
Nersesian said Thursday he'll continue to live in Santa Rosa, splitting his time between Sonoma County, Santa Clara and customer locations around the world.
Agilent's Santa Rosa campus is headquarters and research-and-development center for the measurement group. It has about 1,150 employees.
"Santa Rosa will continue to be a very strong part of Agilent," Nersesian said.
S??was his choice to head the measurement group. "He's a very strong leader with great people skills and business skills," Nersesian said.
