About me

I am an Associate senior university lecturer at the Department of Astronomy and Theoretical Physics at Lund University, Sweden. My work mainly concerns the formation and evolution of galaxies. In 2010 I completed my Ph.D. at the Institute for Theoretical Physics at the University of Zurich. After this I took up a fellowship position at the Kavli Institure for Theoretical Physics, University of Chicago. In 2013 I became a lecturer in the astrophysics group at the Univerity of Surrey, and in 2016 I started my current position at Lund University.

The VINTERGATAN simulation

Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical and kinematical structures that encode its history. To understand the origins of these trends, we have carried out and dissected a new high resolution cosmological of a Milky Way-like galaxy, VINTERGATAN. (Vintergatan is the Swedish word for Milky Way, literally The Winter Street)


Simulation details and results in:

  • Virtual Reality visualisation

    Within the DATA theme (2017-2018) at the Pufendorf Institute for Advances Studies, I collaborated with Mattias Wallergard (Design Science, LTH), Simon Holk (Student, LTH) and researchers at Humlab (Henrik Garde, Diederick C. Nierhorster) to develop a Virtual Reality framework for visualising astrophysical data. For more information about this effort, click the presentation below.

  • This work continues thanks to a grant (Visualising the assembly of the Milky Way. PI: Stefen Lindgren, Humlab, LU, 2018-2020) from the e-Science Collaboration (eSSSENCE) in Sweden.
