Hi there, I'm Géraldine Räuber.

I'm a physicist having completed my PhD as part of the Belle II collaboration. My research has taken me deep into the world of high-energy experiments, where I’ve worked with large datasets and complex analytical methods to study fundamental particles.

Along the way, I’ve developed strong programming skills and a passion for coding, which I apply to everything from data analysis to creating tools that (hopefully) solve everyday problems. Now, I’ve just started as a Graduate Developer, working with SAP technologies and programming in ABAP.

I enjoy taking on coding projects that challenge me to think critically and creatively, whether it’s optimizing algorithms or exploring new applications of machine learning. I’m always looking for opportunities to learn and contribute to exciting new ideas. Feel free to take a look at my CV in English icon or in French icon.

When I’m not immersed in physics or coding, you can find me playing the flute, keeping my plants alive, or experimenting in the kitchen.

Got questions? Just hit me up at hi[at]syntaxerror.ch. Unless it’s spam. Spam gets the silent treatment.

What's new


  • Know more about what's beneath the leaves - For example, did you know peanuts grow underground?
  • Ever heard of physics tree? - Discover what the academic family tree of famous physicists looks like.
  • Explore SQL or BDT Tutorial - Now available on GitHub, they offer offer a great resource to enhance and expand your knowledge.
  • Have a look at some french-written Recettes - New recipes are added every now and then. A random selection of recipe has been added to give ideas when they don't come by themselves.

What's special today


  • Not all fruits and vegetables grow at the same time. For example, apricots and cucumber are currently in season in Europe. More fruits and vegetables are listed in my project Fruits and veggies.
  • In Japan, the year is traditionally divided into 72 moments of season. The current Sekki is Taisho (tr. Greater Heat) and the Kō is Tsuchi uruōte mushi atsushi (tr. The ground is damp, the air hot and humid). Check out the rest of the seasons in my blog post titled Haikus and seasons.
