Brief bio
Currently I am a postdoctoral fellow at Algebra Group - UiT, The Arctic University of Norway under the supervision of Cordian Riener.
In Dec 2020, I received doctorates, under a cotutelle agreement, in Computer Science from the University of Waterloo, Canada under the supervision of Éric Schost and George Labahn and the Sorbonne Université (Paris 6), France under the supervision of Mohab Safey El Din.
Before that, I obtained a master degree in Fundamental Computer Science from the École Normale Supérieure de Lyon, France in 2017.
Research interests
Computer Algebra (Symbolic Computation), Polynomial System Solving, Computational Algebraic Geometry.
