He obtained a Ph.D. from the University of Waterloo with Efficient Text Searching, supervised by Gaston Gonnet and granted in 1989.[3]

His research interests include:

  • Algorithms and data structures. His contributions[4] include algorithms for string search such as the Shift Or Algorithm and algorithms for Fuzzy string searching, inspiring[5] also the Bitap algorithm; co-author of the Handbook of Algorithms and Data Structures ISBN 0-201-14218-X with his former Ph.D. advisor Gaston Gonnet,
  • Information retrieval. Co-author of Modern Information retrieval Addison Wesley, ISBN 0-201-39829-X, first edition in 1999 and a second edition in 2011 that won the 2012 book of the year award of the Association for Information Science and Technology.[6]
  • Web search and mining. Baeza-Yates founded in 2002 and directed until 2005 the Center for Web Research in the Department of Computer Science of the University of Chile. His latest work on this area focuses on bias on the Web,[7] giving the Gödel Lecture 2017 in Viena.[8]

Dr. Baeza-Yates was awarded one of the Spanish national Computer Science awards in 2018[9] as well as the J.W. Graham Medal in Computing and Innovation by the University of Waterloo, Canada, in 2007. In August 2008, Dr. Baeza-Yates was proposed for the first time to the Chilean National Prize in Applied Sciences (Premio Nacional de Ciencias Aplicadas). He has been proposed again most of even years when this award is given. He is corresponding member of the Chilean Academy of Sciences (2003),[10] founding member of the Chilean Academy of Engineering (2010), and corresponding member of the Brazilian Academy of Sciences (2018). He is a fellow of the Association for Computing Machinery (2009).[11] and an IEEE Fellow (2011).[12]
