As a Senior Scientist, you will design and conduct scientifically high-quality research within GTK’s strategic research programmes.

Your responsibilities include the analysis, interpretation and modelling of hydrogeochemical and hydrogeological data to investigate interactions between water and the geological environment.

In your research, you will apply isotope tracers and other environmental tracers to determine groundwater origin, flow paths and residence times in Arctic and boreal regions. You will have a strong understanding of the impacts of climate change on groundwater recharge, storage, flow dynamics and water quality. You will publish research results as a corresponding author in international peer-reviewed scientific journals. The position also involves acquiring research funding and preparing research proposals in collaboration with national and international partners. You will serve as a scientific lead, principal investigator, or project manager in research projects.

In addition, you will supervise and mentor early-career researchers, doctoral students, and other research trainees.

Within the Water and Mining Environment Solutions Unit, you will be part of a team of approximately 50 experts working on groundwater research, hydrogeochemistry, groundwater flow modelling, reactive transport modelling, mining environments, and water management-related challenges. The position of Senior Scientist is located within the Hydrogeology and Modelling Team.
