Fabio Gonzalez O.
CSE, M.Sc., Ph.D.
Director

Fabio is a Full Professor at the Department of Computer Systems and Industrial Engineering at the National University of Colombia, where he leads the Machine Learning, Perception and Discovery Lab (MindLab). He earned a Computer Systems Engineer degree and a MSc in Mathematics degree from the National University of Colombia in 1993 and 1998 respectively, and a MSc and PhD degrees in Computer Science from the University of Memphis, USA, in 2003. His research work revolves around machine learning and information retrieval, with a particular focus on the representation, indexing and automatic analysis of multimodal data (data encompassing different types of information: textual, visual, signals, etc.). Some of the applications of his research work include content-based image retrieval of biomedical and natural images, automatic image annotation and visual content mining, among others.

Claudia J. Becerra
B.S, M.Sc and Ph.D (c) in Systems and Computer Engineering

I am a 3rd year Ph.D. Candidate in Computer Science in National University of Colombia (Universidad Nacional de Colombia) and my research focuses in Recommender Systems. I have been working in recommender systems since my Master program. I had the opportunity to intern in the Grouplens research lab at the University of Minnesota. Currently I am experimenting with user profiles built using the information available of the  products that users consume, studying how people can better interact with them to enrich, and tune, the recommendations they obtain.
