Ruben SOMMARUGA

Ruben Sommaruga is Full Professor of Limnology at the Department of Ecology, where he acted also as Director between 2012 and 2020.

He graduated in Biological Oceanography at the Faculty of Sciences in Montevideo (Uruguay) in 1989, and in 1993 received his doctor degree from the University of Innsbruck. His interest for aquatic sciences brought him as post-doc researcher to several institutes in Europe, USA, and South America. In 1998, he completed his habilitation requirements in the field of Limnology at the University of Innsbruck. He has been elected Fellow of the European Academy of Sciences and of the Association for the Sciences of Limnology and Oceanography, as well as awarded several international prizes including the Recognition of Professional Excellence in Limnetic Ecology by the International Ecology Institute and the Scientific Award from the Principality of Liechtenstein among others.

His general field of scientific interest is aquatic ecology, and within this general area, he has expertise in (micro)plankton ecology, biogeochemistry, photoecology, and global change effects in mountain lakes. Research on these topics is done in different types of aquatic ecosystems mainly in the Alps, but also in the Andes, Himalaya, Bale Mountains and Greenland.

Ruben Sommaruga is Subject Editor of Aquatic Microbial Ecology and member of the Editorial Board of the Journal of Limnology. He was member of the Scientific Board from the Austrian Science Fund (FWF) between 2008-2020 and member of the Faculty of 1000. He acted before as Associate Editor of Photochemical and Photobiological Sciences and of FEMS Microbiology Ecology, as well as in the Editorial Board of Scientific Reports and Journal of Plankton Research.
