Since 2017, I am employed as researcher at the Department of Geology, Lund University, and my field of excellence is in dendrochronology (tree-ring research), peatland development, long-term (hydro)climatology, and quaternary sciences. In my research, I have been using growth patterns of trees to study and date large-scale climate changes, hydrological shifts in peatlands, avalanches, historical buildings, archaeological artefacts, and 17^th century Flemish art. One of the primary aims of my on-going research is to study what effects tree colonization in peatlands have on hydrology, vegetation, and carbon sequestration in such ecosystems. To answer my research questions, I’ll use data generated from living and subfossil peatland trees, as well as approaches including laser ablation spot analysis (LA-ICP-MS) and stable isotope analyses (δ¹³C and δ¹⁸O). I will also perform field studies of changes in moisture content in peat soils representing different tree coverage, compile and analyse data from an existing network of sites where changes in peatland water tables, tree growth, and carbon fluxes have been monitored, and use examine tree growth responses to environmental changes and the on-going tree colonization.
