PerkinElmer appointed CEO and President Robert Friel to the additional job of chairman of its board of directors. The company said that the appointment is part of a leadership succession plan that it adopted in 2007. Friel succeeds Gregory Summe, who did not stand for re-election. Friel started at the company in 1999 as chief financial officer and he was promoted to president and chief operating officer in 2007. He took the CEO spot from Summe last year.
