Research interests

My research addresses Algebraic Analysis and Topological Data Analysis

Algebraic Analysis investigates systems of linear partial differential equations by algebraic methods. It elegantly combines methods from Algebraic Geometry, Algebraic Topology, Category Theory, and Complex Analysis. Many special functions in the sciences are encoded by a holonomic annihilating ideal in the Weyl algebra and can be investigated by means of D-modules. In this area, I focus on computational aspects and applications – among others, maximum likelihood estimation of statistical models.

Topological Data Analysis analyzes the shape of data by topological methods. It has concrete applications in neurosciences and machine learning, for instance. One main tool is persistent homology. It associates persistence modules and so called barcodes to datasets, from which one easily reads topological features. Behind the scenes, algebraic structure theorems keep the machinery running. My emphasis in this area lies on advancing the algebraic tools.
