Research Interests:
Many Malassezia species are part of the cutaneous microflora commonly found on animals and human. Their presence is often associated with skin disorders, e.g. dandruff and seborrheic dermatitis. Unique for most of the Malassezia species is a lipid-dependency, which can be tracked back on the absence of a fatty acid synthase. Therefore, specific inhibitors for Malassezia lipases are thought to be extremely effective against these organisms.
The project aims to find the natural substrate of the lipases as well as their inhibitors, which are of high value for personal care products as they might be an effective supplement in anti-dandruff formulations.
