Master of Science in ecology/limnology at the University of Innsbruck in 1998, on ecological evaluation of running waters in Luxemburg with application of geographical information systems (GIS). Ph.D. thesis at UIBK-IZL since 1999 on GIS, remote sensing and image analysis in limnology. Expertise in assessment of habitat and anthropogenic impact on running waters and lakes, environmental information systems (remote sensing, photogrametry and environmental classification).

Diploma at the University of Padova (Italy), on photosynthetic bacteria of a meromictic mountain lake in the Eastern Italian Alps. Ph.D at the University of Innsbruck in 2000, on general limnology, phytoplankton and littoral diatoms of high mountain lakes in the Eastern Italian Alps. Expertise in phytoplankton and diatom analyses of high mountain lakes and in enclosure experiments. Participation in national and EC research projects concerning lowland river margins and glacial streams (ERMAS 1995-1997, AASER 1996-1998).


Tasks:

UIBK-IZL convenes the work package on "evaluation: environmental status of lakes" (WP 8) and with UIBK-IMG co-ordinates the hydrological studies within EMERGE. UIBK-IZL runs the Experimental site at Gossenkollesee in the Austrian Tyrol, including the installation and operation of large, automatic sediment traps in collaboration with EAWAG; and the ana--lyses of diatoms from these traps. UIBK-IZL is responsible for all field sampling at the Classification and Validation lakes in the Tyrol Lake District and will organise the GIS mapping programme for the this region. In the RILA Mountains UIBK-IZL co-ordinates the survey of catchment data (vegetation, soil cover, geology) and analyses diatoms in the sediment cores and interpret the geochemical changes in the lake sediment, in co-operation with IZ-BAS. Along an altitudinal gradient of 5 lakes catchment parameters are surveyed and analysis of long term trends in limnochemistry in relation to climate, weathering, soil development and vegetation are carried out to statistically evaluate the driving factors for limnochemical changes in these lakes. UIBK-IZL participates in fish sampling in Austria, Bulgaria, Norway and Spain for biochemical analyses and trains local staff if more than one sampling is scheduled. Oxidative stress and biochemical parameters in the liver of all fish (GSH, GSSG, vitamin C, riboflavin, tocopherol, carotenoids, enzymes linked to detoxification) are analysed in Innsbruck; and pollutant fluxes and impact within the food chains are assessed in collaboration with CSIC (POPs), NIVA (stable isotopes and metals), CNRIII (pigments and carotenoids in sediment). In two Bulgarian lakes UIBK-IZL supervises the complete fish sampling programme including test fishing, sampling of blood (blood ions) and gills (scanning electron microscopy), in co-operation with IZ-BAS.
