(CNN) -- Marissa Mayer, who was Google's first female engineer and its 20th employee when she joined that company in 1999, has been named CEO of Yahoo. 

She's the fifth CEO in as many years at that struggling company. Monday's announcement has caused ripples in the world of technology as people expressed surprise that Mayer would leave Google and that Yahoo has landed such a charismatic leader. 

Here's a quick guide to some of the most interesting and water-cooler-worthy facts about the 37-year-old. (We know what you're thinking. And yes -- an 11-point list can successfully illuminate decades of a person's personal and professional life. Of course it can.)

1. She's responsible for the clean look of Google.com. The minimalist home page, with plenty of white space and a single search bar in the center, is said to be the brainchild of Mayer, who has overseen the launch and development of many of Google's iconic products. 

"Google has the functionality of a really complicated Swiss Army knife, but the home page is our way of approaching it closed. It's simple, it's elegant, you can slip it in your pocket, but it's got the great doodad when you need it," she told Fast Company in 2005. "A lot of our competitors are like a Swiss Army knife open -- and that can be intimidating and occasionally harmful." 

2. She specializes in artificial intelligence. Mayer holds bachelor's and master's degrees from Stanford University. For both degrees, Mayer focused on artificial intelligence, which has become a core area of focus for Google, a company that has introduced autonomous cars and whose computers are trying to use equations to understand human speech. She told CNN she holds several patents in AI and interface design.
