Department of Environmental Geosciences (EDGE)

EDGE Enviromental GeoscienceEDGE takes an interdisciplinary approach to investigate aquatic and terrestrial processes that control the environment. Chemical, physical, biological, and geoscientific concepts and methods are applied in all research practices: starting from field observations and experimental work to arrive at a molecular scale mechanistic understanding and quantitative modelling. We are well equipped to seize opportunities presented by developments in areas such as nanogeosciences, molecular biology, isotope geochemistry, environmental chemical analytics, chemical speciation and modern hydrogeology.

Our overall goal is to understand the complexity of the environmental systems and to apply fundamental insight to solve the most pressing environmental problems of today and tomorrow.

Stephan M. KRAEMER

Management Board

Stephan Kraemer is the head of the Department of Environmental Geosciences at the University of Vienna and co-founder of the MINERVA (Mineralogical Preservation of the Human Biome) research platform. He is a low temperature geochemist interested in molecular scale bio-mineral interactions. A particular focus is the reactivity of biogenic molecules including ligands, reductants, enzymes and nucleic acids at mineral surfaces. His research interests include interactions of DNA with mineral phases in the context of long-term eDNA and aDNA preservation. He uses stable isotopes including strontium, mercury and other transition metals as process- and forensic tracers. His laboratory includes a MC-ICPMS isotope lab, trace metal analytics and spectroscopic facilities and methods for mineral characterization. After studying Earth Sciences at Ruhr Universität Bochum, he obtained his PhD in 1997 under the guidance of Prof. Janet Hering (CALTECH) and held positions at UC Berkeley and ETH-Zürich before moving to Vienna in 2006.

Veer Vikram SINGH

I am a Ph.D. candidate at the Department of Environmental Geosciences (EDGE), University of Vienna. I completed my M.Sc. at the Indian Institute of Technology Bombay, India, where I studied clay chemistry and mineralogy to understand the formation of bole beds (clay-rich horizons) present in Deccan basaltic flows. My doctoral research is a part of the research platform MINERVA (Mineralogical Preservation of the Human Biome from the Depth of Time), a collaboration between EDGE and the Department of Evolutionary Anthropology of the University of Vienna. In my doctoral research, I am focusing on understanding the roles of environmentally relevant minerals such as clays, iron oxides, hydroxyapatite and calcite in preserving the DNA against the common degradational agents such as nucleases, reactive oxygen species and ionizing radiation. My work will help develop a better understanding of the role of minerals in the long-term preservation of the human genome in the environment.
