Apple Inc. may have a solution to quash criticism that it’s lost its innovation mojo. The company recently hired Yoky Matsuoka, the co-founder of Google X, a semi-secret division within Google responsible for things like smart contact lenses and driverless cars.

Matsuoka, who originally moved to the U.S. from Japan to pursue a tennis career but has since earned a Ph.D. in robots from MIT, will report directly to Apple AAPL, -3.17% COO Jeff Williams. Williams oversees Apple’s futuristic health initiatives, such as HealthKit, ResearchKit and the new CareKit.

Apple confirmed the hiring to MarketWatch, but did not provide details about her role. Matsuoka’s LinkedIn page has been updated to reflect the move, but she doesn’t list a specific title.

Matsuoka most recently served as CEO of Quanttus, an app that gathers biomedical data, such as blood pressure, so that users can monitor key health trends. Her role at Apple will likely involve the company’s new smart-health initiatives, which includes apps that track health data via Apple Watch.

Before Quanttus, Matsuoka served as vice president of technology at Nest Labs, the home-automation company bought by Google, now a part of Alphabet Inc. GOOGL, -2.41% , for $3.2 billion in 2014. From 2009 to 2010 she was head of innovation of Google, where she co-founded Google X, the company’s secretive “moonshots” research and development arm.

In May 2015, Matsuoka turned down a vice president job at Twitter Inc. TWTR, +2.03% after she was diagnosed with a life-threatening disease, which she announced publicly in a Medium post.

The hiring of Matsuoka comes one week after Apple reported its first ever quarterly decline in iPhone sales. The company has been trying to reposition itself as a software and services company as hardware growth slows and the company loses steam in China, its largest market outside the U.S. Last quarter, services revenue jumped 20% year-over-year to $6 billion.

Shares of Apple have declined 1.5% over the past three months and 26% over the past year, underperforming the Dow Jones Industrial Average, which is up 8% over the past three months and down just 1.7% on the year. The shares traded up 0.3% to $95.45 Wednesday morning.
