Fabian Schmidt, Cosmologist

I'm a scientific staff member (Forschungsgruppenleiter) at the Max-Planck-Institut für Astrophysik (MPA), Garching (near Munich), Germany. I am interested in all aspects of cosmology, though I have also worked on weak gravitational lensing and cosmic ray physics.


deals with the question of what our Universe as a whole is made of, as well as its history and evolution. Two of the most pressing mysteries in cosmology are the nature of dark matter and dark energy, which appear to make up 96% of the Universe's current energy budget.

Gravitational Lensing

According to Einstein's theory of relativity, gravity affects not only ordinary matter, but light as well. The intense gravitational pull of galaxies and clusters of galaxies lets them act as cosmic magnifying glasses. This allows us to measure all matter, both visible and dark.

Cosmic Rays

Earth is constantly bombarded by extremely energetic particles that have been generated by cosmic particle accelerators far more powerful than the ones we can build on Earth. We still do not know what these accelerators actually are, although there are several suspects.

About me

Having grown up in Bonn, Brussels and the New York City suburbs, I did my undergraduate at Humboldt University, Berlin, graduating with a (Diplom) thesis on cosmic gamma rays. I then moved to Chicago for graduate school. You can find my CV here.

    Job opportunities

    In case you are interested in joining my group as a student or postdoc, please see the information below.


    My students are members of the IMPRS (International Max Planck Research School on Astrophysics) at the Ludwig Maximilians University Munich. The online application can be found here (deadline: November 15 of each year).


    MPA has openings for MPA fellowship positions which are announced on the AAS job register in October of every year. Applications to the MPA positions will also be considered for independently funded postdoc positions in my group.


    Due to administrative and logistical hurdles, I do not accept internships from students who are not local (in the Munich/Garching area or nearby). For more explanation, see here.
