Research Interests
My research focuses on neutrino physics beyond the standard model, looking at neutrino data from tritium beta decay, accelerator neutrinos and atmospheric neutrinos, to help understand why neutrinos behave so differently from their standard model prediction.
As a member of the KATRIN experiment, I use the high-precision measurements of the tritium beta decay recorded with KATRIN to search for additional neutrino interactions with a generalized effective-field-theory approach. These so-called generalized neutrino interactions (GNIs) can give hints to any new physics that contributes to the weak interaction at higher orders. This analysis does not only profit from KATRIN's current data set, but will keep being relevant after the upcoming TRISTAN detector upgrade. I also contributed to better quantifying the systematic effect of KATRIN's cryogenic tritium source, which is one of the leading systematics of the neutrino mass analysis.
In the T2K experiment, I am trying to combine the impact of both the accelerator-neutrino and atmospheric-neutrino data to search for neutrino non-standard interactions (NSIs), a subset of the GNIs. These impact the oscillation behavior of the neutrinos and might be able to explain current differences in neutrino oscillation results between experiments. I am also supporting the operation of the near detector data acquisition system (ND280 DAQ).
As part of the Hyper-Kamiokande collaboration, I am currently taking on a leading role in the construction of HK's outer detector. I'm involved in setting up the required logistics, developing installation procedures and coordinating between subgroups. I am furthermore contributing to the development of the data acquisition system and am part of the near site safety committee.
