Commissioning of the small-sized-telescopes for CTA: The small-sized telescopes (SSTs) of the Cherenkov Telescope Array will concentrate on the highest energies due to their large effective detection area, which will be achieved by the planned 50 telescopes. For their final design, three different SST designs were proposed. I supported one of the teams in commissioning and verifying their prototype, which resulted in our design being selected. In particular, I led the high-level analysis, which was used to analyse observations from a data taking campaign, demonstrating the high quality of the camera design.

Optimisation of very-high-energy gamma-ray analysis: Due to the indirect measurement technique of ground-based gamma-ray telescopes, complex statistical analysis methods need to be applied. The performance of these methods determines the scientific prospects, in particular for very short observations, such as transient events, or for studying the most extreme energies of objects. I have been working on the optimisation of various analysis steps for different telescopes. For the gamma-ray telescope FACT, I supported the development of the simulation in the beginning of the observation phase of the project. I established the deconvolution procedure, resulting in the publication of the first energy spectrum for this instrument [2]. For the telescope system MAGIC, I built on my experiences to contribute to the deconvolution. I optimised the gamma/hadron separation and the energy reconstruction, both based on machine learning. This resulted in an improved energy spectrum, extending to higher energies. I also initiated and led the development of an automatic database-based analysis chain, providing comparable and uniform analysis products, essential for instance for population studies, stacking analyses and observation prospects for future experiments.

Association of Active Galaxies and linking multi-wavelength counterparts with machine learning: The space-based telescope Fermi-LAT conducted the deepest all-sky survey in gamma rays so far. Despite outstanding achievements in assigning source types, several hundreds of detected point sources remain without plausible associations or are associated with active galaxies of uncertain type. Assigning active galaxy classes to unassociated and uncertain sources, and linking counterparts to the unassociated ones, will refine our knowledge of gamma-ray emitting objects tremendously. With this knowledge we can carry out population studies of active galaxies, search for dark matter, or follow-up transients. Furthermore, we can address questions, such as the origin of astrophysical neutrinos and ultra-high-energy cosmic rays, cosmological evolution, and emission and acceleration mechanisms of active galactic nuclei (AGNs). I developed a machine learning algorithm, which used multi-wavelength data to improve the source classification capabilities. At the same time, it offers the possibility to determine the most likely corresponding counterpart. This proof of principle allows to exploit this novel approach for much larger datasets and catalogs.

I have been awarded an ARC Discovery Project (“The Dawn of Extreme Gamma-Ray Astronomy”) with my mentor Prof Gavin Rowell with a competitive grant income of $0.35 million, where I will lead the optimisation of the CTA data analysis and the analysis of the first data of CTA’s small-sized telescopes.

I was actively involved in the preparation of two DFG (German Research Foundation) funding applications for the Collaborative Research Centre 823 (“Statistical Modelling of Nonlinear Dynamic Processes”), which have been awarded 8.3 million euros (2013 - 2017) and 8.7 million euros (2017 - 2021).

I received travel funds via the Project-based Personnel Exchange Programme by the German Academic Exchange Service for three research stays at Columbia University, New York, USA. From the same service, I also received travel funds to attend an international conference in Busan, South Korea, and acquired funds for a summer intern from Germany to work with me in Australia.

Astronomical telescope observations are often awarded on a competitive basis, using peer review in a manner similar to research grants. I have been successful with six observation proposals including the gamma-ray telescopes HESS (2020) and MAGIC (2015 and 2017) and the X-ray telescope Swift-XRT (2013). The HESS observations proposals included joint observations and follow-up programs with the Australian Square Kilometre Array Pathfinder (ASKAP) and the Australian Telescope Compact Array (ATCA), and Deeper Wider Faster (DWF).

I am very active in teaching and supervision. I assist A/Prof Martin White in teaching the Introductory Data Science course with over 100 students every semester, and with Prof Gavin Rowell, in teaching the second-year level astrophysics practical project components. These activities are very effective to attract highly skilled students from relevant fields to the groups' research projects. I currently supervise one and co-supervise four PhD students and train them in particular in programming, software development, statistics, data analysis and high-performance computing - skills that cannot be learnt in a lecture. I also actively recruit students by regularly offering summer internships to undergraduate students from the University of Adelaide, and also from overseas via special programmes (

In order to attract researchers from other Australian institutes, I have organised and run a school for the analysis of CTA data, serving as a base for future collaborations within Australia and beyond. I also promoted international collaborations by designing new research projects and by applying for travel grants for their realisation via the competitive Programmes for Project-Related Personal Exchange (PPP) of the German Academic Exchange Service (DAAD).

At the University of Dortmund, Germany, I gave numerous lectures on behalf of my supervisor in the courses “Astroparticle Physics” and “Statistical Methods of Data Analysis”, including gamma-ray astronomy, data mining and deconvolution techniques. For these courses, I also led the weekly workshops, including the development and assessment of exercises, and assessed the written and oral exams at the end of the course.

I was also regularly invited to teach at several schools, for instance about statistics and machine learning at the MAGIC software school, about CTA analysis at the analysis school for CTA-Australia and about fundamental physics with Cherenkov telescopes at the Bad Honnef astroparticle physics school.
