I am an applied mathematician who is especially interested in environmental and dynamical modelling, as well as sensitivity analysis. My PhD project The Effect of Water Column Dynamics on the Microbial Food Web and Transfer to Higher Trophic Levels is a part of the project How can fisheries contribute to a more sustainable future?.

The Effect of Water Column Dynamics on the Microbial Food Web and Transfer to Higher Trophic Levels

As a PhD candidate, I will take part in developing a depth resolved Minimum Model (see Thingstad et al. 2007; Thingstad 2020), that can be utilized to analyse the effect of water column dynamics on the microbial food web and transfer to higher trophic levels (e.g., fish).

Methods of global sensitivity analysis (see Saltelli et al. 2010; Pianosi et al. 2018) will be applied on key model output, with the aim of analysing the effects of water column dynamics on the microbial food web and transfer to higher trophic levels, whilst accounting for uncertainties in the model.

The model simulations will also be confronted with observations from two contrasting environments: The Baltic Sea, which is a murky environment due to high supplies of dissolved organic matter (see Andersson et al. 2018) and the Red Sea which is a highly transparent environment (see Calleja et al. 2018).
