Adam Bosworth, Google’s executive in charge of leading the company’s health information efforts, has left the company to pursue other interests.

“Adam is a great talent and was instrumental in starting Google Health,” Google spokesman Steve Langdon told MM&M in an e-mailed statement. “He is now on vacation and has decided to pursue other opportunities after that.”

Marissa Mayer, VP of search products & user experience, will take over Google’s health team until a new leader is appointed, Langdon said.

“Google is moving forward with work on our health products,” Langdon added.

Bosworth joined Google three years ago and had been thought to be working on a major new health service at the company. Google watchers have speculated the new, yet-to-be unveiled service could be centered on ideas ranging from health information search to ways to allow consumers to create their own personal medical records.

Prior to joining Google, Bosworth was a VP at business software provider BEA Systems. He previously held management positions at Microsoft where he worked with Web coding system Ajax, which has given rise to several Web 2.0 applications.
