Currently he is full professor at the CS department of the University of Chile, where he was the chair in the period 1993-95. He is also the president of CLEI, a Latin American association of CS departments; and coordinates the Iberoamerican cooperation program in Electronics and Informatics. His research interests include information retrieval, algorithms, and information visualization. He is co-author of the book Modern Information Retrieval published in 1999 by Addison-Wesley, as well as co-author of the second edition of the Handbook of Algorithms and Data Structures (Addison-Wesley, 1991). Ricardo is the co-editor of Information Retrieval: Algorithms and Data Structures (Prentice-Hall, 1992). He has also published extensively in journals published by ACM, IEEE and SIAM. He has been visiting professor or invited speaker at several conferences and universities all around the world, as well as referee of many journals, conferences, and granting agencies.
