Synaptics, a developer of human interface solutions for mobile computing, communications, and entertainment devices, has appointed Russell Knittel as Interim president, chief executive officer and board of director following the resignation of Thomas Tiernan as president, CEO and a director.

The company said Knittel has held key executive positions with Synaptics for over ten years and most recently served as executive vice president.

Knittel also served as CFO of the company for the majority of his tenure from April 2000 through September 2009.

Knittel said, his involvement with Synaptics for more than 10 years has given him a deep appreciation of the company’s many strengths, including innovation, product offerings, customer service, and employee talent and creativity.

"During this important transition period, the Board of Directors and I are committed to working with our employees to continue to enhance our business and take advantage of the expanding market opportunities," Knittel said.
