Gustatory perception

The gustatory system is a gateway to nutrient sensing, yet it is the least understood of our senses. We ask how taste is represented in the human brain and how neural taste processing links to behavior. To address these questions, we also develop long-needed stimulation and experimental protocols suited for psychophysical and psychophysiological studies and we are assessing the reliability, validity, and practicality of these measures and procedures.

Taste memory

In a new line of research, we investigate the properties of taste memory: Can we store taste information? What is the capacity of this store and what are the rules for optimal retrieval?

Contextual effects on taste

We constantly sample our environment for information or cues that arouse expectations about future events. What are the neural mechanisms by which expectations shape taste perception? What are the behavioral consequences of our neural states representing food in contexts? What is the role of prior experience and knowledge on taste and food perception?

Visual perception of food

Together with Jens Blechert (Salzburg) and Niko A. Busch (M√ľnster) we have developed a comprehensive database consisting of over 1,000 food and non-food images and relevant meta data for research on food perception, eating, and appetite. You can find more information here:
