About me

I am working as a Researcher in the Cosmology, Particle Astrophysics and String Theory group. I am a member of the H.E.S.S. Collaboration and of the CTA Consortium.

I am group leader of the Swedish H.E.S.S. team, member of H.E.S.S. management (Collaboration and Executive board), co-convener of the Astroparticle Physics Working Group, and Gamma-Ray Multiwavelength liaison for the collaboration.

Teaching

At Fysikum I am regularly teaching FK 5001, Introduction to Astroparticle Physics. My teaching experience includes courses and seminars in Astrophysics at Stockholm University and Technical University Munich.

I am strongly committed to public outreach and regularly give public presentations, collaborate on popular science communication in various media. One of the joys of my job is that I get the chance to talk to non-specialists about the research that is currently going on in astronomy, astrophyisics, cosmology and adjacent fields of science.  I am always happy to talk to school groups, astronomical societies or, really, any interested people. I am also the outreach representative of the CTA Consortium for Sweden.

Research

As an experimental particle physicist and astrophysicist by training, I am involved in data analysis and data interpretation for HESS, where my scientific interests focus on the physics of extragalactic gamma-ray sources and connected fundamental physics. I am member of the MAGIC/H·E·S·S/VERITAS joint observations team as well as of the M87 team. I collaborate in the AGN physics working group of HESS and in the Telescope Design, AGN Physics, Calibration and Outreach groups of the Cherenkov Telescope Array consortium.

Research Interests:

VHE γ-ray astrophysics; Active Galactic Nuclei: X-ray/VHE γ-ray observations of blazars, fast variability, monitoring; Multi-Wavelength Observations; Fundamental Physics with VHE γ-ray observations (Lorentz Invariance; Quantum Gravity); Multi-Messenger Astrophysics; Constraining the Extragalactic Background Light; Imaging Air Cerenkov telescopes; Pointing Monitoring for the CTA Telescopes; Light Sensor and Camera verification fot the CTA Telescopes; Advanced Computing and GRID; Future Cherenkov Astronomy Facilities (Large-Size Instruments; Cherenkov Telescope Array)
