Moin!

I'm an early stage researcher with main interests in particle physics phenomenology and precision calculations. I'm currently located at DESY (Hamburg).

What I'm interested in

Most scientists have a hard time explaining to a broad audience what they are doing. Unfortunately, I'm not an exception (you've been warned!). If you concatenate all my previous publications, a relatively clear picture emerges.




Obviously, I'm interested in Higgs physics. The calculation of loop corrections also seems to play a crucial role in my life.

What does this mean?
Spoiler: we don't know!

The common lore is that our understanding of the world surrounding us can be quantified by the level of agreement between observations (e.g. physics experiments) and predictions that are based on mathematical models incorporating what we call laws of physics. Some laws turn out to be more fundamental than others in the sense that they can explain a plethora of observations in very different situations e.g. at very different energy scales. In many cases, assuming different laws can lead to different predictions that can be compared with experiment - allowing us to falsify our models. Sometimes we are lucky and a more-fundamental theory predicts the existence of effects that we haven't even thought of (i.e. suggest new experimental setups).
One very successful model in this game is the Standard Model of Particle Physics (SM), which predicts, among other things, a fundamental particle: the Brout-Englert-Higgs boson (often just "the Higgs"). Luckily, a Higgs boson has been found in 2012 at the Large Hadron Collier (LHC). However, we don't actually know whether it's the Higgs of the SM or whether it may be part of a more fundamental theory. People have been thinking about this possibility for ages. Therefore, the discovery of a Higgs offers a huge playground. On the other hand, the level of precision at which we are comparing our model predictions to experiments is also crucial. Every theory-number as well as every experimental result is only true within some error bars! If those error bars are too large, clearly we can no longer distinguish two theories that yield similar, yet different, predictions. This is why both, theory and experiment, work very hard to provide as many correct digits as possible in their results. Finally, I'm able to position myself in this short story as one of the individuals that cares about said precision predictions in theories that feature more than a Higgs boson.
