Zygo CEO steps down, board names interim CEO

MIDDLEFIELD, Conn. (AP) -- Zygo Corp. said Monday that its CEO and chairman, Chris Koliopoulos, is stepping down in what it described as a "mutual decision" with the scientific instrument maker's board of directors.

Zygo said the board has appointed Gary Willis to serve as interim CEO and Michael Kaufman to serve as chairman. Willis is a former CEO and chairman, and is now on its board of directors.

"The board appreciates Dr. Koliopoulos' service to Zygo and we wish him the best in his future endeavors," said Carol Wallace, who chairs the company's corporate governance and nominating committee. "The board of directors is focused on achieving Zygo's full potential for the benefit of our shareholders."
