The main focus of Niiranen’s research is on marine food web dynamics and how they respond to changes in multiple environmental and anthropogenic stressors. She uses modelling as her research tool and is currently working with a size-structured food web modelling approach in a Baltic Sea Bonus project BlueWebs. Her recent research also includes study of cross-scale dynamics in Arctic marine systems. Niiranen is a co-lead of the Marine Theme at the Stockholm Resilience Centre.
Niiranen has a PhD in marine ecology from the Department of Ecology, Environment and Plant Sciences (DEEP) at the Stockholm University. For her PhD research she studied how multiple interacting drivers affect the dynamics of Baltic Sea food web. She holds an MSc in hydrobiology from the University of Helsinki and worked at the former Finnish Institute of Marine Research and the Baltic Nest Institute before her becoming a post-doctoral researcher at the SRC. While at SRC, she has worked in projects GreenMAR, INSPIRE, and BlueWebs.
Niiranen participates actively in the work of the International Council of the Exploration of the Seas (ICES) expert groups such as the Working Group on the integrated assessment of the Baltic Sea (WGIAB) and Working Group on Comparative Analysis between European Atlantic and Mediterranean marine ecosystems (COMEDA).

Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective is to allow different ac...

Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, organisms and ecosystems. Substantial recent advances reveal a pattern of stronger responses (positive or negative) o...

Modeling social‐ecological systems is difficult due to the complexity of ecosystems and of individual and collective human behavior. Key components of the social‐ecological system are often over‐simplified or omitted. Generalized modeling is a dynamical systems approach that can overcome some of these challenges. It can rigorously analyze qualitative system dynamics such as regime shifts despite incomplete knowledge of the mod...
