Michael Kühl


I am a microbial ecologist with broad interdisciplinary interests ranging from technicalities of sensor development, over a fascination of single cell microbiology and behaviour, to studies of microenvironmental controls and microbial interactions in aquatic communities and ecosystems. I enjoy working at the boundaries and interfaces of different scientific disciplines and implement sensor chemistry, photonics, and advanced imaging in my research.

Microenvironmental ecology of surface-associated microbial communities and marine symbioses.
Microsensor and imaging techniques for biogeochemical analysis of microenvironments, mass transfer and metabolic rates.
Optical properties and photobiology of sediments, photosynthetic tissues and biofilms.
Microbial behaviour and activity in gradient systems.
