Scientific coordination (Jun 2019 - Mar 2023):

• DFG-funded CRC Elasto-q-mat (Transregio 288)
  Current scientific coordinator: David Kaib
  
  

Research interests:

• Extraction of magnetic interaction parameters for real materials based on first principles calculations (e.g., projED method, perturbation theory)
  
  
• Effects of frustrated magnetic interactions in real materials (e.g., on the dynamical structure factor, magnetic torque response)
  
  
• Role of anisotropic and higher order magnetic interactions (e.g., Kitaev interaction, Dzyaloshinskii-Moriya interaction, four-spin ring exchange)
  
  
• Kitaev candidate materials, organic charge transfer salts, pyrochlore materials, and many more
  
  

PhD thesis:

• First Principles Studies of Frustrated Spin Systems: From Low-Energy Models to Experiments.
