Title of Project

Isotope fingerprint of metal deficiency in soils

Project details

I will seek to understand the reasons for Zn and other vital metal deficiency in diet, resulting malnutrition and increased child mortality. Therefore, my PhD research will focus in understanding the origin of deficiency in soil and crops grown on metal deficient soils. I will measure full vital metal concentrations and Zn-isotope compositions in soil samples, to distinguish between inherent low Zn content of soil and Zn depletion through soil over-use. In addition, my research involves the testing of Zn-fertilisation and other potential remedial efforts to recover Zn-depleted soil profiles and crop samples in affected areas from the ‘Zinc saves Kids Initiative’ (

Postgraduate personal details

I graduated at the University of Mainz in Germany, where I combined petrographic-, petrologic-, as well as structural observations with zircon (U-Pb) and garnet (Lu-Hf/Sm-Nd) geochronology, to reveal the history of Archaean granulite-facies paragneisses from central Swaziland. These rocks are among the oldest preserved continent-derived sediments on Earth. Until the end of 2014, I worked for the Geological Survey of Ecuador (INIGEMM) and the Escuela Politécnica del Ejército (ESPE) in Quito, where I conducted my own research project about the El Oro Complex in SW Ecuador.
