## Shirly Geffen

Prof. Dr. Shirly Geffen is an assistant professor (*Juniorprofessorin*) at the Mathematical Institute. She is concerned with the fine structure of operator algebras, in particular with regularity properties of entangled products of C*-algebras with amenable group actions.

## Anna Gusakova

Prof. Dr. Anna Gusakova is an assistant professor (*Juniorprofessorin*) at the Institute for Mathematical Stochastics. Her major research area is Stochastic Geometry. This is a branch of modern probability theory, which is investigating various random geometric objects, starting from lines and polytopes and finishing by general random closed sets.

## Marlies Pirner

Prof. Dr. Marlies Pirner is an assistant professor (*Juniorprofessorin*) of applied mathematics. She works in Applied Analysis on kinetic equations. In this description, the time evolution of a gas is described by using a probability density. This description is used for instance for plasmas and many astrophysical phenomena. Here, she considers questions in mathematical modeling and theoretical questions such as existence, qualitative behavior of solutions and convergence to equilibrium.
