I am currently a principal researcher and manager at AI platform team of Microsoft AI and Cloud. My current research interests include computer vision, learning based computational photography and AI for content generation. I always look for addressing industry scale challenges, and keep an eye on practical machine learning settings. During the past eight years, I have been working closely with different product teams including Bing map, XBox/Kinect, Microsoft Pix Camera, Swift-Key and Cognitive services etc, and shipped several important technologies to those products. Prior to the current position, I was a lead researcher at Microsoft Research Asia lab.
