Professor in geochemistry, mineralogy and petrology; Deputy Head of Department for teaching, Department of Geoscience and Natural Resource Management, Copenhagen University 

Short biography 

Tod has a Ph.D. in geology from the University of Canterbury (Christchurch, New Zealand) and worked in Australia and the USA before landing in Denmark. He is an igneous petrologist and geochemist and has carried out research on for example the granites on Bornholm, andesitic volcanoes from New Zealand, and flood basalts from Greenland and Iceland. His research focuses on the application of geochemistry and especially radiogenic isotope systematics to understanding magma genesis. Much of this work involves Sr isotopes, and has included using small-scale variations in Sr isotope compositions in zoned feldspar crystals as a means of tracking changes in magma compositions and magma chamber processes during crystallisation. He has also worked with archaeological materials, primarily using Pb isotope compositions as a means of tracing the origin of silver and copper in archaeological artefacts.
