About Oscar’s research

I research in theoretical astrophysics, with a focus on how stars and galaxies form. What makes the Universe, given 13.8 billion years of evolution, produce the incredibly diverse types of galaxies that we can observe today? How did the Milky Way form? Is there a limit to how small or large galaxies can become? Why do some galaxies stop forming stars? These are examples of questions that me and my research group are trying to answer, among other things using large numerical models on supercomputers. These simulations make it possible to study the physics that actually governs the development of galaxies and how different phenomena such as galaxy collisions affect their lives.

In brief

Born: 1980
Interests: I love being with family and friends. I am especially happy when I can spend a whole afternoon cooking and listening to music. I enjoy reading, and in my free time, I mostly choose literature that has nothing to do with my research area.
Other: I have lived and conducted research in Switzerland, USA, and England before returning to Sweden.

I am part of the Young Academy of Sweden to be able to work for good research having a more prevalent presence in our society. Questions that are important to me are how science and scientific thinking are communicated, mainly to young people and children, and how equal and transparent career paths for young researchers can be improved. In addition to this, I am interested in the Academy’s policy work, and how we can safeguard and promote independent and well-funded basic research.
