Since December 2016, I am working at DTU Compute in the Algebra Group of the Department of Applied Mathematics and Computer Science. My two-year H.C. Ørsted Postdoc is supervised by Johan Rosenkilde.

## Research interests

My primary interest is the design of**fast algorithms in computer algebra**, and more particularly for computations with

**polynomials**both in

**univariate contexts**(Hermite-Padé approximation, linear system solving, basis reduction, Hermite form computation)

**and multivariate settings**(constrained interpolation problems, change of monomial order for zero-dimensional ideals).

The basic problems mentioned above are

**ubiquitous in algebraic computations**, and I am also interested in studying specific contexts where they occur. This involves

**error-correcting codes**(e.g. the Guruswami-Sudan list-decoding algorithms and the Koetter-Vardy soft-decoding algorithms), as well as

**cryptography**(e.g. in algebraic cryptanalysis, or to increase robustness in Private Information Retrieval).
