I lead the machine learning algorithms and toolkit group in Microsoft’s Cloud and AI division. We develop Microsoft’s machine learning toolkit known to the public as ML.NET. I am also a member of the Apache Software Foundation and was the inaugural PMC chair (VP) of Apache REEF. My work focuses on machine learning techniques, systems therefore and applications thereof. Prior, I lead the machine learning research group of the Cloud Information Services Laboratory (CISL) at Microsoft and prior to that, was a researcher at Yahoo! Research.
