Chang Wang

Technology startup founder and researcher on machine learning & natural language processing


  • I am currently running a New York based technology startup on knowledge extraction from big data using machine learning and natural language processing techniques. Previously, I worked at Bridgewater Associates (Elemental Cognition) and IBM Research both as a researcher. Prior to joining IBM, I received Ph.D on artificial intelligence at the University of Massachusetts at Amherst. I also did internship at Microsoft research (2009), IBM research (2008), and eBay research (2007) on search engine, ranking and sentiment analysis.
