Adam Bosworth, who was charged with developing health information for Google Health, will be leaving the company to pursue other opportunities, the Times Online reported.
John Batelle notes that Marissa Mayer will take over the position.
Bosworth helped develop XML - the Extensible Markup Language - before joining Google three years ago.
Mayer has held many senior positions with Google. In 2002 she was a product manager, but by 2005 Mayer was Director of Consumer Web Products, though ended the year as VP of Search Products & User Experience.
Got to wish them both the best.
