    My current research is focused on gamma-ray astronomy, in particular the study of Galactic sources of high-energy gamma rays. One of my recent contributions was on the detection of the pulsar PSR B1706-44 with H.E.S.S.;this is only the fourth gamma-ray pulsar detected from the ground. I am a member of the H.E.S.S. Collaboration and the CTA Consortium.

    I am also interested in the development of open-source tools for gamma-ray astronomy. In this context, I have made some contributions to the Gammapy software package, have helped preparing the first H.E.S.S. public data release, and have published a technical paper about the validation of open-source tools (the paper also describes a new method for background modeling).

    Previously, I have been a member of the IceCube Collaboration. During that time, I have carried out a measurement of the energy spectrum and the flavor composition of the cosmic neutrino flux observed with the IceCube experiment. For more details, check the corresponding publication or have a look into my PhD thesis.
