About

My work is in the intersection of algebraic geometry and commutative algebra, frequently with a view towards applications. I am happy to use tools from infty-cats, stack theory to representation theory to combinatorics and computational tools such as M2. I work in particular on deformations of zero-dimensional objects, Bialynicki-Birula decompositions, Hilbert and Quot schemes, applications to tensors and secants varieties, applications to motivic homotopy theory etc.
See my papers or my poster for details. If you want to discuss, just send me an email!

News

• Forward notice: I will be opening a 2-year postdoc position; the call should open officially very soon (I'll put the info) with the deadline on 1st February 2025. The position will start around September 2025, but negotiable. If you think you might be interested feel free to mail me with questions.
• Another Math PhD Open course will be offered in the academic year 2024/25. Michel Brion will talk about algebraic groups. Stay tuned for more information. (It is not excluded that there will be more PhD Open courses in between.)
• I put a list of open problems in zero-dimensional deformations on arXiv. Enjoy! Also thanks to Tony Iarrobino for the initial push.
