I investigate the effects of wetland restorations and creations on mainly birds but also other organisms such as fish, amphibians and arthropods. Even though my main research areas are conservation biology, community ecology, and biodiversity, I am also interested in evolutionary ecology and animal behaviour.

I aim to investigate what factors are the most important in order to increase and maintain bird diversity when restoring and creating the wetlands, for example, wetland size or landscape setting. The largest part of my research focuses on wetland creation. I study created wetlands in Uppland, where I look at what environmental variables in created habitat are related to bird, fish, and amphibian diversity. More specifically, I look at what affects the bird community in created wetlands - their abundance, richness, and reproductive success and relate this to fish and amphibian communities. While bird data was collected using field observation, fish and amphibian occurrences were determined using environmental DNA metabarcoding sampling. I also try to relate species interactions and the intervention outcomes. Some of the possible interactions are a conspecific and heterospecific attraction, predation, and competition. 

In other projects I am trying to evaluate wetland restorations for birds, where we try to narrow down the magnitude of wetland restorations in Sweden and quantify the species-specific responses. While the data set is rather heterogenous, we need to employ more creative data analysis tools in order to standardise the results.

I finished my PhD degree in 2021 with the tittle Wetland creation and restoration for biodiversity. Outcomes of conservation initiatives to benefit birds, amphibians and occasionally fish. On the other hand, my Master’s degree thesis at Lund University investigated the effects of urbanisation on the great tit’s cognition. I am also a bird enthusiast, and I have been working in the field with a project involving northern wheatears, and nest box populations of tits, and continually am involved in standardised bird ringing.
