The aim of my doctoral research is to investigate carbon cycling and dynamic factors affecting carbon sink potential in the common reed (Phragmites australis) across coastal archipelago reed belts. Plant biodiversity in littoral systems along the Baltic Sea has reduced as distribution of the reeds has expanded. However, previous research on the reed’s role in coastal carbon budgets to combat climate change has been limited. This research focuses on exploring the reed’s role in carbon cycling across temporal and spatial scales to better elucidate the reed’s role in coastal carbon budgets.

The intensity and frequency of marine heatwaves have increased globally not sparing an already stressed Baltic Sea. My research focuses on the impact of such episodic events on benthic communities and the maintenance of their respective ecosystem functioning of bioturbation and nutrient cycling.

My research focuses on coastal bacteria, their diversity and metabolism, using advanced techniques that examine their DNA and RNA. These techniques reveal the types and functions of bacteria. I use computer tools to analyze and interpret the data from these experiments. Among the constraints that bacteria face are changes in nutrient availability and the risk of being killed by viruses, called bacteriophages.

My research investigates the identity, activity and functioning of marine microbial communities in coastal environments. My aim is to find out how the microbial communities respond to changes in their environmental conditions (e.g., warming), interact with each other and other organisms, and what is their impact on the coastal carbon cycling for example via methane production and oxidation.

My research focuses on biogeochemical processes in human-impacted aquatic systems, such as eutrophic coastal seas and freshwater lakes. Within CoastClim I am studying the coupled dynamics of carbon, nutrients and other elements in coastal sediments of the Baltic Sea. Sediments are important reactors in which microbes transform elements from one form to another, controlling their eventual fate. For example, carbon can be buried in complex organic molecules that resist degradation, thus acting as a carbon sink, or converted to greenhouse gases such as carbon dioxide and methane that escape to the atmosphere. We want to understand the controls on these processes to better predict carbon and nutrient cycling in the future.

My interest lies in understanding global carbon cycling, especially in coastal marine systems. I aim to acquire more information on blue carbon sequestration in coastal sediments. Sediment depositional environments in coastal systems have the capacity to store carbon on geological time scales, so studying the burial rate and source of sediment carbon is crucial for understanding the global carbon cycle under the effects of climate change. Currently, my work focuses on determining the macroalgal contribution to the sediment carbon sink through studying biomarkers (phenolic compounds).
