I have broad experience in scientific research and computational physics, mathematical modeling and statistics. The mathematical modeling I am experienced with includes: Black-Scholes Partial Differential Equations Foward Curves Monte Calo Simulations Time Serie Analysis (ARIMA, GARCH Models for High Frecuency Data) Radom Walk Matrix Decomposition Cholesky Factorization Mainly, in the last two years I am used to program in Perl, Python and C/C++, I did learnt Fortran (F90) programing but not using a lot nowadays. The codes I created are focused to run on supercomputers with parallel programing using OpemMP and/or MPI under Linux (RedHat/CentOS/Fedora) systems, Linux clusters and High Performance supercomputers. (with IBM AIX, or Linux Debian and Solaris) For statistics, I mainly used Matlab / Octave and R program, but I try to make everything I can in Python using NumPy as well. From my time in the academia, I am author of several (+25) articles in the area of computational physics, and co-authors of one book chapters, several reports, many lecture material, and a few popular science articles. I have experience in different writing styles and addressing the publication to a diverse audience. I speak fluent Swedish and Spanish and have knowledge of Portuguese, Finnish and German.
