Paris, France Engineer at the IDS Conception Office, and from 2021 to end, System and Network Engineer at the Infrastructure andd Oerational Office

As the activities involved at ANSSI are in relation with critical infrastructures of the state, it is not possible to disclose any further information regarding what I was doing there.
Since 2011 Technical Officer at Crans (volunteering)
Cachan, France Crans is a French nonprofit association who provides an Internet access to 1.250 members based on the student campus of ENS Cachan. While there, I did, amongst other things :
  • Migrating the virtualization cluster from Xen to Proxmox;
  • Updating and maintaining the LDAP server (OpenLDAP);
  • Harmonizing the Postfix cluster configuration and setting up anti-spam measures (Postscreen);
  • Migrating the NFS server and setting (remote) quotas;
  • Setting up a DHCP server failover;
  • Setting up a new Debian/Ubuntu/BSD mirror, and packaging of custom applications;
  • Replacement of a MSA2012i storage system by a P2000 G3 one;
  • Co-development of the Django intranet software and the python codebase we use to manage our users database and its interaction with network/software components ;
  • Setting up a GitLab instance ;
  • Optimizing PostgreSQL server ;
  • Interactions with our suppliers to renew our servers, switches, and ensure warranty continuation ;
  • Writing of documentation on the association's wiki.

Studies

01/10/2014 - 05/12/2018 Modelling and Simulation of the Cardiac Electrophysiology at the Microscopic Scale
CEA Saclay, Gif-Sur-Yvette, France PhD Thesis. During the last decades, studies regarding the prospective impact of the alterations at the microscopic scale of the heart tissue in the appearance of arrhythmias (Brugada's syndrome, atrial fibrilation, early repolarization syndrome…) have been more numerous. The amount of experimental data regarding the behaviours and regulations that occur at a cellular and a subcellular (gap junctions, role of specific ionic channels) is increasing and these data provide an adapted frame for the computational mathematiciens to develop or improve models and confirm their behaviour.

This thesis was aimed at developping a "microscopic" model taking into account the individual geometry of the cells and the gap junctions between them, to enhance our understanding of the action potential propagation in a network of cells.
01/09/2013 - 15/09/2014 Master's Degree of Applied Mathematics, with a focus on Modelling ans Simulation.
ENS Cachan, France Master's Degree with a high focus on Partial Differential Equations, Functional Analysis, High Performance Computing and applications to other scientific topics (physics, medicine, …).

In 2015, this Master's Degree changed of name when it got integrated in Université Paris-Saclay Masters program.
01/09/2012 - 04/07/2013 Agrégation externe of Mathematics (plus Master's Degree of Higher Education Teaching of Mathematics).
ENS Cachan, France Master's Degree of Fundamental Mathematics dedicated to teaching in Higher Education classes.

The goal of this year was to pass the Agrégation Externe of Mathematics, a competition to become a Higher Education Teacher (as all competitions for teaching in France, this one is to become a civil servant, too), and this Master's Degree was mandatory, as one needs such a Degree to pass the competition.
01/09/2011 - 31/08/2012 First year of Masters Degree in Fundamental Mathematics
ENS Cachan, France Topics:
  • Algebra, Modules ;
  • Functional Analysis ;
  • Optimization ;
  • Complex Analysis
01/09/2010 - 31/08/2011 Bachelor Degree of Fundamental Mathematics
ENS Cachan, France This Degree was delivered by Paris VII University, as ENS Cachan is not allowed to deliver Bachelor Degrees by itself.

Topics:
  • Hilbert and Fourier Analysis ;
  • Algebra, Galois Theory, Field Extensions ;
  • Differential Analysis ;
  • Partial Differential Equations ;
  • Integration Theory and Probabilities.
