Marissa Mayer, a 13-year veteran of Google, is Yahoo's new CEO, the company announced on Monday.

Mayer's appointment comes after a revolving door of chief executives at the company including, most recently, Scott Thompson, who stepped down in May after a scandal involving his doctored resume.

Mayer, 37, was employee number 20 at Google and was a crucial asset to the search giant, introducing more than 100 features and products to the site during her tenure. In October 2010, Mayer, who held the title VP of Search Product, began overseeing location and local services at the company.

An engineer by trade, Mayer was among the top echelon at Google with access to company co-founders Larry Page and Sergey Brin.

For Yahoo, the appointment is another shot at reinvention after a slew of would-be turnaround experts including Carol Bartz and Thompson, who's short tenure was marked by a proxy war with Dan Loeb, an activist investor.
