AnHai Doan is an associate professor in the database group at Wisconsin-Madison. He did his undergrad in Hungary, where he ran a profitable cigarette resale business and learned Pascal and English. Next he did his Ph.D. in the U.S., where he started in AI but switched midway to databases (to graduate faster). His dissertation studied schema/ontology matching, and received the ACM Doctoral Dissertation Award in 2003. Since then he has worked extensively in information integration and extraction, structured Web databases, and human computation. He was a Sloan fellow in 2007, and has consulted extensively in industry and government. Currently he's on leave as Chief Scientist for Kosmix, a startup that builds structured databases over social media. When not working, he's traveling and moonlighting on a data integration textbook as well as his memoir in Vietnamese, which details his path from cigarette seller to textbook writer, and the lessons he has learned along the way.
