Research interests 
My research is centered on the combinatorial and algebraic structures associated with walks (a.k.a. paths) on graphs and their applications
throughout mathematics, but also in computer science and physics.
My long term goal is to approach the long standing open problem of enumerating selfavoiding polygons on infinite regular
lattices via a completely algebraic route, by extending techniques from number theory to walks.
I am always keen on discussing research and participating in research collaborations
on a wide variety of subjects, from quantum mechanics to
applied network analysis.

Short bio 
I completed two MSc degrees from the University of Arizona and Institut d'Optique Graduate School in 2009 (Diplôme d'Ingénieur). That same year I was awarded a Scatcherd European scholarship
to fund my DPhil in mathematicalphysics from Keble College, Oxford, which I completed in 2014 under the direction of Prof. Dieter Jaksch. I received a University of Oxford Thesis Prize for my thesis "A graph theoretic approach to matrix functions and quantum dynamics".
Following my DPhil, I held a postdoc position at Oxford funded by the successful EPSRC Grant EP/K038311/1 obtained together with Prof. Jaksch, Dr. Stephen Clark and Dr. Sarah AlAssam. In 2015, I was awarded a three years Research Fellowship by the Royal Commission for the Exhibition of 1851 and chose to undertake it in the group of Prof. Richard Wilson, at the University of York. I am a lecturer (Maître de Conférences) of algebraic combinatorics at the Université du Littoral Côte d'Opale, since September 2018. My full CV is available here.
