Research interests

After finishing my PhD focussing on transplant immunology and metabolic changes in end-stage liver disease/portal hypertension, my interest has evolved into the field of cancer- and immunometabolism.

My current research focus aims to better understand metabolic rewiring in stem cells during cancer development and to investigate the impact of secreted oncometabolites on tumor-infiltrating immune cells.

Techniques, methods & infrastructure

Basic research techniques/models:

  • Standard molecular biology techniques
  • CRISPR/Cas9 gene editing
  • Murine in vivo models
