I am a reader in Mathematics and a Royal Society Short Industry Fellow. I obtained my Diplom and PhD on topics in geometry at TU Berlin. Before joining the University of Leicester in 2007 I hold research positions at TU Berlin the University of Massachusetts in Amherst and the University of Augsburg where I was awarded my habilitation. My research expertise is in surface theory and integrable systems. I currently also work on applications of discrete geometry in machine learning, engineering and chemistry.

I am currently Postgraduate Tutor for Mathematics. I'm also a member of appeals panels and co-director of the VisLab. Elsewhere, I'm an elected member of the standing panel of European Women in Mathematics. I'm an elected member of the SLAM committee of the London Mathematical Society. I’m a member of AIDAM and the Creative Computing Research Group.

My research is in surface theory and its applications. In papers with Burstall Ferus Pedit and Pinkall we generalise methods and statements known in complex algebraic geometry to complex quaternionic line bundles and derive this way new results in surface theory. The main idea of ""Quaternionic Holomorphic Geometry"" is to consider the 4 sphere as quaternionic projective space and use the conformal maps into the 4-sphere as the holomorphic functions of the theory.

I am leading an international network team working on minimal surfaces ""m:iv"" which investigates links between minimal surfaces integable systems and visualisation (originally funded by the Leverhulme Trust, now partially funded by the project Semi-Riemannian Geometry and geometric flows in mathematical physics).

I am a Royal Society Short Industry Fellow, looking at machine learning and discrete Geometry methods for monitoring of particle outfall.

Geometrically inspired discretisation of surfaces play an important role in providing fast and efficient numerical methods to solve PDEs. I'm currently investigating certain discrete curves and surfaces to find efficient tools to solve the underlying differential equations. My current engagement is built on a SPRINT collaboration on how to improve machine learning algorithms via geometric information given by discrete curves.

My research area is in surface theory with applications in machine learning, Engineering, Informatics and Chemistry. The approach to problems is via Quaternionic Holomorphic Geometry which is an efficient tool to study surfaces in 3- and 4-space. Particular interest is in studying the underlying PDEs via integrable system methods, which allows for a reliable discretisation.

Topics for research supervision

  • Integrable systems of Minimal surfaces via isothermic spectral data
  • Discrete Minimal Surfaces
  • Discrete Isothermic Surfaces
  • Applications of surface theory to machine learning 


I am a Fellow of the HEA and received my Habilitation at the University of Augsburg.

I have obtained a wide range of pedagogic experience by teaching at undergraduate and postgraduate level in Germany the USA and the UK. I consider teaching as an integral part of my work: experiences in teaching enhance my views in research and conversely new approaches in research lead to more meaningful teaching. My teaching expertise lies in the area of geometry and visualisation but I also made significant contributions to the curriculum of the Calculus and Analysis stream.
