Internet Services Research Center (ISRC)

The Internet Services Research Center (ISRC) is a specialized research group, focusing on all aspects of internet services. We see applications moving to the cloud, with Web search posing deep technical challenges, and with mobility, social networks, data mining, and system structures seeing huge changes. We work to accelerate innovations in search and ad technologies, and partner with other parts of Microsoft to rapidly deliver them to our search products, customers, and advertisers.
