I’m Principal Applied Science Manager in Search and Artificial Intelligence at Microsoft. I am a Applied Science leader who drives key areas of “query rewriting” for Microsoft Bing. My team is responsible for various systems that search users take for granted, ranging from spell correction, synonym expansion, and query intent classification and rewriting, that help you discover rich content on the web. Microsoft has deeply invested in the deep learning wave, with in-house, very large scale pre-trained models for both NLP and natural language generation. We apply state-of-the-art models in production to bring better search results to Microsoft users.
