Every day at Microsoft, we bring an insatiable curiosity to our work, continually challenging ourselves to rethink what is possible and to push beyond existing boundaries. We build on past innovations to create what comes next—shaping the future and empowering billions of people around the world. Online advertising is one of the fastest‑growing sectors of the internet economy today. Search engines, web publishers, major advertising networks, and ad exchanges serve billions of ad impressions daily, generating terabytes of user interaction data in the process. This rapid expansion has created significant opportunities, alongside complex technical challenges that require intelligent, scalable solutions. The field of computational advertising has emerged as a multidisciplinary field that draws on information retrieval, data mining, machine learning, statistical modeling, optimization, linear algebra, and microeconomics to address the demanding problems inherent in modern online advertising. We are a team that focuses on keeping the Microsoft Advertising ecosystem safe for users and compliant with policies.
