Research

I am a mathematician working in the field of topology, which aims to establish connections between continuous and discrete phenomena.

The ultimate goal of my research is to understand the structure of symplectic manifolds. To do that, I use ideas from Floer theory and mirror symmetry. I am also interested in computational aspects of symplectic invariants.

Currently, I am trying to describe generators for the Fukaya category of homogeneous symplectic manifolds.

Code

• DubrovinDynamics
  This shows the evolution of eigenvalues in the spectrum of the truncated Dubrovin operator of some Grassmannians, as one deforms the bulk parameters.
• Posetroids
  This generates a list of all positroid strata in a given Grassmannian, together with the partial order on them induced by Zariski closure.
• ClusterExplorer
  This is a random walk on the exchange graph of the cluster structure of the top positroid strata. These spaces are believed to support Landau-Ginzburg models for Grassmannians, and the walk allows to study the Laurent polynomials describing the potential in each chart.
