Simon Telen

Max Planck research group leader

I lead the Numerical Algebraic Geometry research group at the Max Planck institute for Mathematics in the Sciences in Leipzig.

I am the diversity officer of the European Mathematical Society Young Academy.

I am the scientific representative of our Max Planck Institute in the Chemistry, Physics and Technology Section of the Max Planck Society.

Research Interests

My research is in computational algebraic geometry, with an emphasis on the use and development of numerical tools. My group works on the solution of systems of polynomial equations and related problems, such as tensor decomposition and algebraic optimization. Recently, there is some focus on computing discriminants, Euler/Feynman integrals, and likelihood geometry.
