I am an astrophysicist working on the dynamics and evolution of disc galaxies, based at the Max Planck Institute for Astrophysics, in Garching, Germany. For my research, I use mostly theoretical tools such as isolated and cosmological N-body+hydrodynamic simulations together with orbital structure theory, and combine these with observations to better understand how galaxies like our own Milky Way form and evolve. I'm particularly interested in the dark matter problem, and in connecting the detailed dynamical processes occurring in galaxies with the wider cosmological context. For more details have a look at the Research tabs and my publication list on ADS.
I am passionate about science outreach and communication and believe that the cosmovision that astronomy imparts us with can help in achieving a fairer and more sustainable future (as outlined by the UN Sustainable Development Goals). In this spirit, I founded and coordinate the award-winning project "Columba-Hypatia: Astronomy for Peace" , funded by the International Astronomical Union's Office of Astronomy for Development, the United Nations Peace-keeping force in Cyprus and the Max Planck Institute for Astrophysics. You can read more about Columba and the various other projects I'm involved with in the Outreach tab.
