Research interests

Mustefa Yasin I have my bachelor's in Land Resources Management and Environmental Protection from Mekelle University Ethiopia, where I also worked as a graduate assistant for three years. I obtained MSc in Tropical Hydrogeology and Environmental Engineering from Technische Universität Darmstadt, Germany. Most of the research work I have done during my Master's thesis and afterwards centred on the application of isotope and chemical tracers in hydro-geochemical studies. My specific research interest is the use of the stable isotopes of water, δ 15 N-NO3 and δ 18 O-NO3 as tracers.

In a practical attachment at the Leibniz Institute for Applied Geophysics, Germany, I examined the effect of high salinity on the determination of δ18O and δ2H values. For my thesis research I used a combination of isotopes (δ18O, δ2H, 3H, δ15 N-NO3, δ 18 O-NO3, 14C, and δ13C) and hydrochemistry to determine the cause of elevated nitrate levels in groundwater of remote deserts in Saudi Arabia.

At the Centre for Coastal Biogeochemistry Research I will be working in a research project aimed at tracing nitrogen sources delivered to estuaries. A multi-tracer approach involving 15N-NO3, 18O-NO3, 17O-NO3 and the stable isotopes of water will be tested. The use as tracer of compounds specific to a particular nitrogen source will also be considered.
