I am a member of the Galaad group at INRIA Sophia Antipolis.

**Research interests :**

My research interests focus on the geometry of algebraic curves and surfaces and their applications in geometric modeling. In this context, I have strong interests in elimination theory, computer algebra and computational algebraic geometry.

*Elimination theory for systems of polynomial equations*: multivariate resultants over blow-up or determinantal varieties, iterated discriminant, multivariate discriminants, closed image of rational maps and equations of their Rees algebras.*Geometry of curves and surfaces*: singularities and pencils of adjoint of rational plane curves, singularities of surfaces, spectrum and total irreducibility of pencils of algebraic plane curves.*Algebraic methods in Computer Aided Geometric Design*: Implicitization and inversion of rational algebraic curves and surfaces (Bézier patches and NURBS) through various matrix-based representations, intersection and self-intersection problems by exploiting and enhancing the link between algebraic and numerical linear algebra technics.

**Ongoing research projects :**

- SYRAM (2015-2016) : MathAmSud research program on « SYzygies of RAtional Maps with applications to geometric modeling » composed by research teams from Argentina, Brasil and France.
- GEOLMI (2011-2015) : ANR research projet on « GEOmetry and algebra of Linear Matrix Inequalities with systems control applications ».

**Upcoming events :**

- BIRS/CMO workshop on Computational Algebra and Geometric Modeling in Oaxaca, Mexico, August 7-12, 2016, co-organized with Ron Goldman and Hal Schenck.
