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. The main topics of my research are: 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 hydrochemistry and isotope hydrology
