Karim Temsamani, former managing director for Google Australia, has become the head of Google's Asia-Pacific operations.
His most recent role was Google's vice-president of new products and solutions for the Americas region.
"Temsamani returns to Asia as Google president of Asia-Pacific sales and operations," said a Google spokesperson. "[He will oversee] Google's sales and operations across the Asia-Pacific region, determining the strategy for 16 offices and the regional business strategy for Google products, including AdWords, AdMob, Google Maps, Google Apps for Business, DoubleClick Ad Exchange, YouTube, and AdSense."
Temsamani was Google Australia's managing director from August 2007 to December 2010, when he was promoted to be the company's vice-president for global mobile operations.
Nick Leeder subsequently became Google Australia's managing director.
Prior to joining Google, Temsamani worked at Fairfax Media for just under five years.
He takes over the role of David Alegre, who is now Google global head of partner business solutions after long-time staffer Marissa Mayer left in July 2012 to become the president and CEO of beleaguered rival Yahoo.
Alegre is currently based in Google's headquarters in the US.
