Research

The long-term objective of my research program is to gain a basic understanding of the molecular properties of food components, which will enable a systematic approach to food quality control, process improvement and new product development.

My main research interests are:

  • application of spectroscopic methods to study food systems
  • structure-function characterization of food peptides and proteins with specific bio-activity, health-enhancing or techno-functional properties

Teaching

Please note: I am not currently accepting new graduate students.
