Biography
Ricardo Baeza-Yates is a professor of the practice and the director of research at Northeastern University's Institute for Experiential Artificial Intelligence, based in Silicon Valley.
Baeza-Yates came to Northeastern after serving as chief technology officer of NTENT, a semantic search technology company based in California. Prior to these roles, he was vice president of research at Yahoo Labs in Sunnyvale, California from August 2014 to February 2016. Before joining Yahoo Labs in California, he founded or led Yahoo Labs in Barcelona, Spain; Santiago, Chile; Haifa, Israel; and London.
Baeza-Yates is a part-time professor at the Universitat Pompeu Fabra in Barcelona, Spain and the Universidad de Chile in Santiago. Until 2004, he was a professor and founding director of the Center for Web Research at the Universidad de Chile.
Baeza-Yates is a co-author of the best-seller Modern Information Retrieval textbook (Addison-Wesley, 1999), whose 2011 expanded edition won the ASIST Book of the Year award. He is also a co-author of the second edition of the Handbook of Algorithms and Data Structures (Addison-Wesley, 1991) and co-editor of Information Retrieval: Algorithms and Data Structures (Prentice-Hall, 1992), among more than 600 other publications.
Baeza-Yates served on the board of governors of the IEEE Computer Society from 2002 to 2004, and on the ACM Council from 2012 to 2016. He has received the Organization of American States award for young researchers in exact sciences, the Graham Medal for innovation in computing from the University of Waterloo, the CLEI Latin American distinction for contributions to computing in the region, and the National Award of the Chilean Association of Engineers, among other distinctions. In 2003, Baeza-Yates became the first computer scientist to be elected to the Chilean Academy of Sciences and, since 2010, he has been a founding member of the Chilean Academy of Engineering. He is a fellow of the ACM and the IEEE.
