My research focuses on the understanding of phytoplankton ecology using a variation of omics and mass spectrometry tools. Here, I use a combination of Secondary Isotope Mass Spectrometry and bulk measurements to quantify relative contribution by phytoplankton groups to nitrogen and carbon fixation, as well as nitrate and ammonium assimilation. I also study the effects of environmental factors on the production of cyanobacterial toxins and mapping of their diversity and abundance in Swedish waters.

My research interests span from open ocean/coastal biogeochemistry of nitrogen, carbon and sulphur to cycling and emissions of oceanic trace gases (such as nitrous oxide, methane, carbon-monoxide, and dimethylsulphide), measurements of short-lived intermediates of the nitrogen- and sulphur-cycle (hydroxylamine, nitric oxide, dimethylsulfoniopropionate, dimethylsulfoxide) and biogeochemical time-series observations. Moreover, I am coordinating the activities of the Time-Series Station Boknis Eck (Eckernförde Bay, SW Baltic Sea): www.bokniseck.de.

My research interest includes the community composition and distribution patterns of non-cyanobacterial nitrogen fixers as well as the abundance and distribution of the nifH gene.

I am a marine ecologist, with special expertise in eutrophication and a strong interdisciplinary reach toward environmental economics, politics, and social sciences. My role is bridging science to policy, through participation in scientific projects and expert groups. In my work I have concentrated especially on developing decision support tools that rely not only on traditional but also advanced approaches.

My research interest lies in benthic nitrogen turnover in coastal systems and its corresponding effects on eutrophication dynamics and ecosystem health. My current research focusses on nitrous oxide cycling in Baltic Sea coastal sediments, the role of organic carbon quality for benthic nitrate-reducing processes such as denitrification and dissimilatory nitrate reduction to ammonium, and internal nitrogen loading from the Baltic Sea coastal zone.

My overall research theme is trying to understand the functioning of biogeochemical systems by means of ocean models. Research interests include Baltic Sea eutrophication and deoxygenation, and climate change effects on regional as well as global marine biogeochemistry.

My research interest includes various topics, such as bacterioplankton community composition in gradient systems, the microbial food web with special focus on the sulphur- and nitrogen-cycle, the ecology of biofilm forming microbial communities, esp. regarding microbial epibionts, as well as environmental risk assessments.

I am interested in exploring climate change in the past, present and future ocean and to provide new solutions for sustainability. Most of my work centered around the nitrogen-cycle in some sense, and I have a passion for anything around nitrogen-fixation and nitrous oxide turnover. I am especially interested in mining the biodiversity of organisms involved in nitrogen turnover, and how they respond to climate change including ocean acidification, deoxygenation and warming. In my group, we are combining high throughput genetic mining and meta-omic modeling with biogeochemical rate measurements, chemical profiling using micro-sensors and oceanographic modeling to explore past and present climate change events, and to predict future scenarios.

The essence of my work is to support building and implementing regional environmental policy for protection of the Baltic Sea especially in the field of nutrients and hazardous substances as pressures to the marine environment. I also facilitate regionally coherent and sustainable maritime spatial planning processes. The Baltic Marine Environment Protection Commission HELCOM aims for a healthy Baltic Sea environment that can support a wide range of sustainable economic and social activities, and for nutrients this means the goal of a Baltic Sea unaffected by eutrophication. The Baltic Sea Action Plan updated in 2021 with the Regional Nutrient Recycling Strategy also adopted in 2021 provide the policy framework and strategic tools with practical measures on how to achieve that goal.

My division is responsible for the planning of the national monitoring in the Lithuanian part of the Curonian Lagoon and the Baltic Sea, analysis of the national monitoring data, data and information submission to international and national organizations (e.g., ICES, EEA), as well as implementation of EU Directives, Regional aggreements (e.g., WFD, MSFD, HELCOM BSAP) and national initiatives seeking for a good marine environmental status. My overall interest is to understand the processes that cause the changes of the marine environment.

I have a Master’s degree in Ecology and PhD in Chemistry, more about my scientific experience:

My research interest lies in modelling biogeochemical processes such as the nitrogen-cycle, as well as the circulation in the Baltic Sea at various scales (seasonal, climate). I am also interested in sub- and mesoscale processes in the central Baltic Sea including Gulf of Finland and Gulf of Riga, as well as hypoxia in the central Baltic Sea.
