Biography

I was born in Concepción, Chile, on September 1977, and received my B.Sc. and Eng. degrees from the Universidad de Concepción, Chile, in 2002. Since there I've been working as a member of the Department of Computer Science at the Universidad de Talca, Chile. At this moment, I am finishing my doctoral studies at Carleton University, Canada.

Research

My research interests include, but are not limited to:

My Doctoral Thesis, entitled "Self Organizing Maps Constrained by Data Structures" is advocated on the generation of enhacements to the Self-Organizing Maps (SOM). I investigate ways to improve the SOM capabilities by defining SOM-based strategies that learn the data distribution and its underlying structure in a more accurate manner. Particular interest is placed on a subset of such variants which utilize a tree as their underlying data structure.
