Research interests

  • Higher-order corrections to Higgs Boson masses in supersymmetric quantum field theories
  • Low-energy effective field theories and their capabilities compared to complete models
  • Extended Higgs sectors
  • Split Supersymmetry


PhD Topic

In my PhD I study 2-loop corrections to Higgs Boson masses in the complex Next-to-Minimal Supersymmetric Standard Model (cNMSSM) in a special renormalization scheme to give a new estimate of the theoretical uncertentaies of missing higher-order corrections.

(Under)Graduate Studies

  • During my master thesis I developed a computer tool to match arbitrary QFTs that involve very high mass scales onto low-energy effective theoies at the one-loop order. This allows e.g. for a precise prediction of Higgs boson masses.
  • My bachelor thesis dealt with relations between dimension six operators in effective field theories and the consequences by the use of equations of motion during basis changes.
