Lichens as symbiotic organism with a poikilohydric lifestyle (water content varies passively with surrounding environmental conditions) are able to cover niches which are mostly not occupied by higher plants. They often occur in extreme habitats like high alpine or polar areas.

The symbiotic partners (fungus, algae/cyanobacteria) are colonized by unique bacterial communities and all components together form specific association patterns along different elevational gradients and furthermore in-between continents.

Because of these specific associations lichens are perfect model organism to investigate climate-change scenarios along an elevational gradient.

Research Focus Environmental Geology :

Interactions between geogene and anthropogene processes are increasingly in the focus of environmental geology. Environmental sciences are becoming more and more important for the society. Thus, research – and, maybe of even greater importance – teaching of environmental geology is an upcoming task for geologists.

In detail my research focuses on:

  • hydrogeology in populated regions (e.g. drinking water supply and pollution in densely populated alpine valleys)
  • hard rock aquifers in the alpine environment with a special focus on natural tracers
  • didactics in environmental geology
