Microsoft's Senior Vice President Satya Nadella announced yesterday in an internal memo, future management changes of the OSD R&D team at MSN.

As mobile development is one of the top priorities Erik Jorgensen, head on MSN, who was previously responsible for the engineering, editorial, content strategy and media efforts for MSN worldwide, will be replaced by Ted Cahall, so that he can now focus completely on mobile efforts.

He will supervise product strategy and execution on mobile devices and will develop location and mapping services for Microsoft's Bing search engine as well, and, for the next month will work with Ted Cahall and the MSN leadership team to ensure the transition.

Ted Cahall left his post as Chief Technology Officer at AOL and will join Microsoft as Corporate Vice President, September 7th, under Nadella's authority, supervising the MSN leadership team, that includes Scott Moore, Geoff Sutton, John Skovron, Anil Mehra and Erik Zigman.

Cahall worked for AOL, United Online, Bank of America and CNET Networks, where he occupied senior leadership roles.

Marc Davis, former chief scientist for mobile at Yahoo, also joined Microsoft as Partner Architect to the Online Services Division, and is now working for Nadella “on vision and technology strategy.”

He was chief scientist at Invention Arts, he worked at the MIT Media Lab, Interval Research, UC Berkeley before leaving Yahoo a year ago.

Satya Nadella said that these changes needed to be made in the OSD R&D team, “to better align and focus [our] leadership on key priorities across MSN and Mobile.”

He is very excited and says that with the “increasing investments in mobile and location-based services and our great momentum with MSN, putting such strong leaders against our biggest challenges will enable deeper focus on the things that will drive our business forward.”

Satya Nadella is a Senior Vice President and leads Microsoft Corporation's engineering efforts in the Online Services Division, which includes the Search (Bing), Portal (MSN) and Advertising platforms.
