About me

Hello! I am an applied mathematician working at the intersection of discrete mathematics, geometry and (linear) algebra with a strong interest in applications. Currently, I am a postdoc with Renaud Lambiotte at Oxford. Previously, I was a postdoc with Bernd Sturmfels , Jürgen Jost and Raffaella Mulas at the Max Planck Institute in Leipzig and obtained my PhD at Oxford.

Research

My research revolves around graphs and their applications. Over the last few years, I have focused on the concept of effective resistance and how it captures the geometry of graphs. Currently, I am interested in discrete curvature and discrete geometry and related questions on matroids, tropical geometry and algebraic statistics.

I have worked on applications such as power grid robustness, network epidemics and polarization in social networks.
