My main research interests are the protein composition of food crops and wheat-related disorders, especially celiac disease and wheat-dependent exercise induced anaphylaxis. Therefore, I develop new analytical strategies allowing me to study the complex interplay between structure and immunological activity of food proteins and peptides. Our research activities combine our expertise in food chemistry, analytical chemistry, proteomics and immunological assays to study the structure and functionality of proteins.

  • Structure-functionality-activity relationships in plant proteins, especially from cereals
  • Fundamental mechanism of celiac disease and bioactivity of food peptides related to wheat dependent exercise induced anaphylaxis
  • Functionality of alternative plant proteins
  • Targeted and untargeted Proteomics to identify and quantitate plant proteins
