  • Sep 2014 -- Dec 2017
Study of the dimer Hubbard Model within Dynamical Mean Field Theory and its application to VO\(_2\)

Develop Many Body Physics simulations using Quantum Monte Carlo Algorithms. I implemented in Python, and C++ the necessary algorithms for the simulations, data collection and data analysis. I supported the infrastructure where my software had to run. Managing the High Performance computing cluster, having Continuous Integration Services setup using cloud services to insure code quality. Implemented as a side project Sphinx-Gallery which currently powers the scientific Python documentation websites.
