 I'm interested in watersheds and the link between the water quality and the terrestrial system. I finished my PhD in 2007; the title was "Seasonal variation and landscape regulation of dissolved organic carbon concentrations and character in Swedish boreal streams". I now work with a couple of projects where I use statistical modeling to predict water chemistry. One project with Chris Evans and David Cooper at the Centre for Ecology & Hydrology, Bangor, Wales. We are currently applying and developing the PEARLS model on the Krycklan Catchment. I also work with a FOMA acidifciation project where we are improving the models used to assess the anthropogenic portion of the pH decline seen in this region during the snowmelt period. One key variable for my work is dissolved organic carbon (DOC) since it is very important for many of the process in the aquatic system. I have also worked with other constituents such as base cations and contaminants. Most of my work is conducted on data from the Krycklan catchment and the last 2 years I have also been the manager for the Krycklan database.

 I have started as a postdoc at this department in September 2009. My major research focus lies on soil nitrogen cycling and the nitrogen nutrition of plants. I am especially interested in interaction and competition effects between plants and soil microorganisms for different available nitrogen sources. I have studied inorganic nitrogen fertilizer effects on plant uptake capacities and microbial community structures in temperate agricultural systems and organic nitrogen uptake patterns of epiphytic tank bromeliads in the Atlantic rainforest in Brazil. In Boreal forest ecosystems, organic nitrogen compounds have been found to be highly abundant and therefore might have a key role in plant nutrition. However, there is still a lack of knowledge about the actual accessibility of different organic nitrogen forms for plants. Further, it still remains unclear how different soil microorganisms (especially mycorrhizal fungi) influence plant organic nitrogen uptake patterns.

Since March 2009 I have been a postdoc at this department. Here, I will take part in field studies focusing on the successional development of the forest ecosystem, with an emphasis on soil, caused by land-uplift in the Gulf of Bothnia. Soil and vegetation on these rising coastlines develop interdependently over time, and we can therefore study the relationship between soil and vegetation as they develop through time.

 I have broad research interests that revolve around themes critical for understanding belowground dynamics at multiple scales in time and space. More specifically, my major research interests are focused on linking the complex interactions of belowground symbiotic associations (e.g. mycorrhizal fungi), that occur at small spatial scales; to larger-scale processes occurring at the plant level (e.g. plant physiology); up to ecosystems processes, such as the cycling of water, carbon, and nitrogen in natural ecosystems. In my research I combine traditional methods of studying soil ecology with the use of stable isotopes at natural abundance levels. I have worked in a variety of systems, i.e. alpine-treeline of the western United States; dry-tropical forests of the Yucatan Peninsula, Mexico; and shrublands, desert, and pine forests of California and Idaho. Here at SLU, I am involved in a study that examines belowground dynamics of shrubs and tree species to better understand the contribution of belowground processes to the terrestrial carbon budget, and how changes in nitrogen availability may affect changes in belowground carbon allocation.

 I completed my Ph.D. at Idaho State University in Plant Ecophysiology, and since June 2009 I have been a postdoc in the Department of Forest Ecology and Management at SLU with Marie-Charlotte Nilsson. My research primarily focuses on ecophysiology of tree seedlings growing in alpine and boreal environments. I specifically study factors affecting carbon balance in young seedlings (e.g. photosynthesis, respiration, nonstructural carbohydrates, growth) and how these factors relate to successful establishment. I am currently involved in a research project testing the effect of burn intensity on establishment of conifer and broadleaf seedlings in both clear cuts and old growth forest. My research also examines ecophysiology of understory vegetation, such as mosses and ericaceous shrubs, as they relate to forest vegetation ecology and how they affect forest regeneration.
