Employment

PhD in Strongly Correlated Electron Systems

  • Université Paris Saclay (Paris-Sud)
  • Orsay, France
  • Sep 2014 -- Dec 2017
  • 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.
