Forschungsschwerpunkte
Schwerpunkt meiner Arbeit ist das Belle bzw. Belle II Experiment am japanischen Forschungszentrum KEK. In Belle leite ich die Physikgruppe für semileptonische und leptonische B-Meson-Zerfälle, die sich mit der Bestimmung der Cabibbo-Kobayashi-Maskawa Matrixelemente |Vcb| und |Vub|, aber auch mit (semi-) tauonischen Zerfällen befasst. In Belle II leite ich die Kollaboration für die Entwicklung und den Bau des Silizium-Streifendetektors.
