At the South Pole, in the middle of Antarctica, we have drilled deep holes down into the glacial ice to instrument a cubic kilometer of this highly transparent and pristine medium with very sensitive light sensors. This detector called “IceCube” allows us to capture the dim trace of light that some neutrinos leave behind when they interact in the ice. In my research, I use the collected data to study the fundamental properties of neutrinos through oscillations. This talk will highlight some recent results and then dive a little deeper into challenges we had to address in order to analyze the data. Finally, I will present research topics of interest that I plan working on in the near future.
