Research groups

Group AML Karlson

Group AML Karlson studies Food web and Ecosystem ecology, Ecotoxicology and Stress ecology, Environmental monitoring and Stable isotope techniques.

Baltic Sea Fellows

The Baltic Sea Fellows are an interdisciplinary network of researchers at Stockholm University, investigating marine environmental challenges from multiple perspectives. Spanning multiple departments, they combine scientific expertise with policy insight to support sustainable ecosystem management.

About me

Associate professor and docent (equivalent to habilitation) in Marine Ecotoxicology. I received my PhD in Marine Ecology from Stockholm University in 2010. I conducted post-doctoral research at the University of Waikato and University of Otago, New Zealand, and at the Department of Environmental Science and Analytical Chemistry, Stockholm University 2011-2016 (including maternity leave). 

I am the main supervisor to PhD students Marie Ritter (strategic funding from the SU Baltic Sea Centre) and Johanna Fröjd (funded by VR, the Swedish Research council)

During 2022-2026 I was the contract holder for the National Monitoring program for phytobenthos which started in 1993, now I provdie scientific advice reagrding the sampling programme.

I’m also a founding fellow of Björn Carlsons Baltic Fellows, read more by clicking here.

Learn more about the Marine Ecology Laboratory (MEL) and MEL Fytal at DEEP.

I am the couse leader for Ecology/Baltic Sea field courses at the Askö island, obligatory in the 2nd year of the Marine Biology as well as the Biology and Earth Science programmes. I am also involved in the Ecotoxicology course (Bacehlorlevel) and the MSc level course Baltic Sea Ecosystem: Applications, Modelling and Management (given by the SU Baltic Sea Centre to which I'm affiliated).

I regularily supervise Bachelor (kandidat) and MSc (Master) projects, just email me if you want to discuss a potential project! Broadly I supervise projects linked to food web ecology, large scale changes in the Baltic and ecotoxicology.

My research aims to advance our understanding of how individuals, populations, communities and ecosystems react and adapt to natural and anthropogenic stress (e.g. eutrophication, over-fishing, contaminants, invasive species and climate change). I am particularly interested in these topics:

  • Food web ecology and trophic interactions during environmental change
  • Long-term ecological research and co-analyses of monitoring data and archived samples
  • The role of N-fixing cyanobacterial blooms for fish growth conditions
  • The role of invasive species in the Baltic Sea.
  • Applications of stable isotopes and other novel methods in ecology, ecotoxicology and environmental monitoring

My publication list can be found below, as well as on my Research Gate and Google Scholar profiles (see links to the right).

Current projects:

Vetenskapsrådet (2024-2028)

Novel uses for compound specific stable isotopes applied to eco-evolutionary and ecotoxicological research

Baltic Waters (2024-2026):

Has the large scale fishery in coastal areas reduced the abundance of herring in the archipelago – a baseline study of historical data

Recent projects:

  • Tryggers (2023-2025): Do Sticklebacks benefit from Cyanobacterial blooms?
  • Formas (2020-2023): Can cyanobacterial blooms make Baltic Sea fish less toxic? 
  • Naturvårdsverket (Swedish EPA): Time trends in isotope composition of Baltic cod


Synthetic chemicals as a cause of biodiversity loss

Rivers contain mixtures of synthetic chemicals from discharges but the effect on biodiversity is unknown. Discovering to what degree and which synthetic chemicals affect biodiversity will assist water management towards a toxic-free environment.
