Research activities
My research area lies at the crossroads between algebraic geometry and number theory and finds several applications in information theory (cryptography and coding theory).
In my Ph.D thesis (supervised by Yves Aubry) I addressed the problem of determining the maximum number of rational points on singular curves defined over finite fields. My work is based on notions and tools from commutative algebra, algebraic geometry and combinatorics.
Later, my postdoctoral experience at University of South Florida under the supervision of Jean-François Biasse and Xiang-dong Hou has been an opportunity to broaden my research horizons towards some new and/or more applied topics: post-quantum cryptography (isogeny-based cryptography), algorithmic number theory, permutation polynomials, etc. More specifically, in a joint work with Jean-François Biasse and Michael J. Jacobson, we have recently analyzed the quantum security of an isogeny-based cryptosystem called CSIDH, proposed in 2018 by Castryck et al.
I am also a member of the research project ANR manta: Algebraic Geometry and Coding Theory. Within this context, I am interested in codes built over higher dimensional varieties.
