Current tasks

I am responsible for marine ecosystem modelling within SYKE Marine Research Centre.


Research Topics

I am an eager research scientist, passionate of everything sea ice, especially its ecology. I have been working since 2006 with marine biogeochemical models, particularly focusing on ice-covered oceans ecosystems. I am the main developer of the first stoichiometric sea-ice model (http://www.bfm-community.eu), i.e. a sea-ice biogeochemical model that through internal flexible stoichiometry aims to represent the acclimation patterns that organisms manifest in natural environments. 

My scientific interests include:

  • the development of biogeochemical models (including sea ice, pelagic and benthic habitats) at several temporal  (from seasonal to decadal) and spatial (from local to global) scales
  • studies of phenology and phenological changes in polar marine environments
  • studies of the impacts of  climatic and non-climatic stressors on polar marine ecosystems
  • closing of the global carbon cycle
  • climate change scenarios and projections
  • the role of sea ice biota and biogeochemistry in the Earth system
  • adaptations and mitigations
  • development of models suitable for ecosystem management and as tool for decision makers
  • sicence communication, journalism and popularisation.  



I have a Master in Biological Oceanography (2005, Tuscia University, Italy) and PhD in Oceanography (2009, University of Bologna, Italy). Previously, I worked also at CNR (Venice, Italy), Finnish Institute of Marine Research (FIMR, Helsinki, Finland), Tallin Univeristy of Technology (Tallinn, Estonia), and Finnish Meteorological Institute (FMI, Helsinki, Finland).
