# Welcome!

Welcome to the Department of Mathematics at Stockholm University. We offer a wide range of education programmes and conduct research in most mathematical branches.

# The Department of Mathematics would like to welcome two new members.

## Josefin Ahlkrona |
## Sofia Tirabassi |

Josefin received her PhD from Uppsala University in 2016, where she studied with Per Lötstedt. She joins the Department as associate senior lecturer following a stint as a researcher at the Christian-Albrechts-Universität zu Kiel. Josefin's research interests are in computational geosciences, and in particular in climate modelling. | Sofia obtained her PhD in 2012 from Universita degli Studi de Roma Tre, where she was advised by Giuseppe Pareschi. Following postdoctoral appointments in Warsaw and at the University of Utah, she spent several years as senior lecturer at Bergen University. Sofia works in algebraic and arithmetic geometry. |

# Congratulations to Dan Petersen on receiving the Wallenberg Prize of the Swedish Mathematical Societ

Dan has been awarded the prize for his outstanding contributions to algebraic geometry, and in particular for his results concerning homological stability and cohomology of moduli spaces of curves. He has also discovered a counterexample to Faber's conjecture on tautological rings.

# Nada becomes part of the Department of Mathematics

Nada at Stockholm University will be part of the Department of Mathematics from 1 January 2018
