My name is Guido Masella and I am a Physicists, coder, and GNU/Linux enthusiast.

Phisics

Currentely I am a post-doctoral researcher in the Quantum Matter Theory Group (QMT) at the Institut de Sciences et d’Ingénierie Supramoléculaires (ISIS) and University of Strasbourg

I got my Master’s degree in Physics at University of Pisa in late 2015. For a short period in 2016 I worked as a trainee for the Italian National Council of Research (CNR) on an experiment employing ultracold atomic gases.

In 2017 I moved to Strasbourg joining the group of Prof. Guido Pupillo. I got my Ph.D in Physics on December 6th, 2019.

From February 2020 I am a post-doctoral researcher working together wih Prof. Guido Pupillo and Prof. Nikolay V. Prokof’ev on Diagrammatic Monte Carlo methods for Effective Field Theories and Dipole Fermions (link here).

My main research interests are the study and development of numerical methods for accurate descriptions of many-body interacting systems.

Life

I grew up in San Pietro Infine, a small and beautiful town in the center-south of Italy. I had the immense pleasure to live for almost 8 years in Pisa. In 2017 I moved to Strasbourg, in the exact centre of Europe.

In 2018 I was elected as board member of StrasAIR, an association of international researchers of Strasbourg.

I contributed to the early development of GameTales.it, a videogame-centered news website and of its online community (discord).
