Information Retrieval and Data Mining Research &

Computer Science Teaching

I am Researcher at ICIC-CONICET (Investigador Adjunto) and DCIC-Universidad Nacional del Sur (Investigador categoría III) in Bahí­a Blanca, Argentina, and I am teacher of Simulation and Scientific Computing courses.

I graduated as Computer Engineer in 2006 and had a PhD in Computer Science in 2010 at Universidad Nacional del Sur.

I've worked on research and teaching since 2005.

I'm married and have three kids.

 * Scientific Computing Methods - (Métodos de Computación Cientí­fica) - (2005 - 2006) → Programa


My research interests are artificial intelligence and machine learning, more specifically data and text mining. I've worked mainly on evolutionary computation and developed most of my research work on contextual information retrieval and bioinformatics problems.

ICIC-CONICET is part of the Bahía Blanca Scientific Technological Center. It has been created as a double dependent research entity and encourage the research on several Computer Science fields, such as Artificial Intelligence, Visualization and Computer Graphics, Scientific Computing and Bioinformatics, Software Engineering and Information Systems, and Distributed Systems. 

I am member of the Bioinformatics and Chemioinformatics Research Group and the Information Retrieval Research Group.
