Over:

Research Interests
• Mass cultures of algae.
• Photobiology: mechanisms, kinetics and molecular biology of photoacclimation in unicellular planktonic and benthic algae. 
• Remote sensing and optical characteristics of lakes, seas and intertidal sediments, and inherent and optical properties of phytoplankton and sediment parameters like chlorophyll and silt content.
• Primary production of phytoplankton and microphytobenthos in estuaries and development of new (optical) techniques to measure primary production.
• long term time series of phytoplankton biomass and activity
• Ecology of Stromatolites, especially with regard to photosynthesis and primary production.
