About
 |
PositionCurrently I am a researcher at the LaFHIS gropu in ICC-CONICET / FCeyN-UBA. My research topics are parallel and distributed software design and development. My advisor was Sergio Yovine. I've also been for the last few years a teaching assistant in a 2nd year undergraduate CS course: "Algorithms and Data Structures II", covering the topics of abstract data type design and implementation, algorithmic techniques like sorting algorithms, and algorithmic time complexity analysis. Areas of expertiseI have extensive experience developing in C/C++ in the Linux platform, along with industry-standard frameworks and libraries like Boost and QT. To a lesser degree I have development experience in Python and use it as a tool for most of my scripting needs. I have also experimented --among several other packages-- with Cython (a translator from python to C) for code optimization and Scipy (a scientific python package). Past experienceMy past research experience includes work in the field of theoretical optics; topics being the study of the Zernike polynomials as means of representation of visual aberrations, and algebraic transformations of said polynomials. I have worked in the field of software engineering, my Master's Thesis being in the topic of data structure optimizations for model checking of timed automata. I have industry experience in the fields of entertainment (software development of casino electronic games like slot machines and electroinc roulette) and control systems (software development in oil stock accounting and reconciliation for gas stations). In both fields I worked in dependable embedded systems with tight memory and timing constraints. I have done freelance work for the optics industry -- design and development of lens design software.

Current Projects
Currently I'm working on a multi-target parallel/distributed code generation scheme from a parallel specification.
