Research interests
I use
computational methods to address problems in the area of
condensed matter and statistical physics. My most recent
projects are in the areas of

Computing
My computational work has involved the use of
- Monte Carlo methods
- Molecular dynamics simulations
- Langevin dynamics simulations
- Construction of ab initio atomic pseudopotentials
I run programs at
I have designed and written all of the computer programs that
I use for my research by myself and from scratch. I
make extensive use of GSL and LAPACK libraries, and I also use
Mathematica to plot and manage data obtained from the computer
simulations.
