Summary
I currently hold a permanent position at the Computer Science Department of Barcelona Tech (UPC).
Previously, I was a Visiting Professor (2008-2009) at the Economics Dept. of Universidad Carlos III de Madrid, and from 2003-2008 I held a "Ramón y Cajal" Research position at the Applied Mathematics Dept. of Universidad de Valladolid.
From 1997-2003 I was Associate Professor at Mathematics Dept. of Universidad Simón Bolívar (Venezuela) and also work part-time (2001-2003) as researcher at the Instituto Tecnológico Venezolano de Petróleos (INTEVEP).
My scientific career comprises two stages (so far): I began doing research and publishing papers on Finite Model Theory and Computational Complexity (i.e. Descriptive Complexity),
but since 2010 I have focused my research and publication efforts in Financial Time Series Analysis, Optimization Heuristics and Mathematics of Finance with an emphasis on their algorithmic and numerical aspects (i.e. Computational Finance).
