Researcher in Applied Geochemistry - Reactive
Transport Modeling

REF NR: LTU-3522-2018


Applied Geochemistry at LTU is a dynamic group of researcher devoted to understand the biogeochemical element cycles in natural and antropogenic altered earth systems. Special focus of our group is in sustainable georesource management and biogeochemical element cycling in cold to arctic climate and during climate change. Therefore, we need to expand our group with a geochemist-chemical researcher with numerical and reactive transport modeling capacity, in order to support the group in evaluation and prediction of different geochemical and hydrogeological systems. Additionally, the group will renew its staff in the next years with the need for teaching in Environmental Geochemistry.

Subject description

Applied Geochemistry comprises studies into the occurrence and mobility of the chemical elements in the environment, with a particular focus on methods to prevent or reduce the environmental impact of mining.

Project Description

The mining industry in Sweden has to fulfil new upcoming European legislations concerning limits for emissions of certain elements and compounds to the environment (e.g. nitrate and sulfate). Therefore, there is a need to understand and control the liberation and emissions of these compounds along the mining process. For this purpose, beside thorough mineralogical and geochemical characterization of the solid and aqueous phases of the systems, numerical geochemical modelling (Equilibrium, reactive transport) will be used to understand and predict the behaviour of different compounds and elements from the beginning of the material streams like in flotation, towards downstream systems like mine tailings and receiving watershed.


The candidate should be able to design the data acquisition of each system, analysis and QC of the data and model different geochemical system in saturated and non-saturated flow conditions. One of the main task will be in the first part of the project to use predictive geochemical modelling to access water quality issues in the mining processing (e.g. flotation cells, mine tailings), but should be extended to also to small lab scale experiences (e.g. cell test, column experiment), up to upscaling into watershed.

The main duties are associated to the research, but the candidate should be also motivated and skilled for teaching and project acquisition for its own research. The participation on pedagogical development work is also included in the assignments.


  • In order to be eligible applicants, the applicant must have a doctorate or equivalent foreign degree in geosciences or related topics.
  • You should have extensive experience in design and installation of lab and field experiments for data acquisition and numerical simulations using equilibrium and reactive transport codes in saturated and non-saturated systems.
  • Experience within CO2 sequestration in in geological materials is meritorious.

We expect from you to be highly self-motivated to develop your own research line in the frame of Applied Geochemistry. You are a team player supporting the whole group in research and teaching with your skills. As the group has many projects in South America, Spanish language is an advantage.


The positon is a fulltime fixed-term employment for two years.
