Employment

Software Developer

Working with a high growth open-source software firm focused on Infrastructure and Application Monitoring for any environment.

PhD in Strongly Correlated Electron Systems

Dissertation
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.
