Dr Stefano Ciavatta is a Senior Scientist at PML. Prior to working at PML, Stefano studied for his MSc and PhD (both in Environmental Sciences) at the University of Venice, Italy.

Stefano’s main scientific activity is the development and assessment of biogeochemical data assimilation systems, to improve the simulations of marine ecosystem models (e.g. ERSEM, the European Regional Seas Ecosystem Model). He applies data assimilation also to time series models, to investigate the trend and seasonal cycle of marine biogeochemical data, and to understand changes in the plankton trophic dynamics.

Other areas of research and application are the sensitivity/uncertainty analysis of marine system models and the statistical analysis of monitoring data.

Stefano has been a Lecturer of Mathematics at the University of Venice for four years. He is an active member of the Data Assimilation Working Group of the National Centre for Ocean Forecasting (NCOF) and Data Assimilation expert in ESA’s Ocean Colour – Climate Change Initiative (OC-CCI).

He is also an occasional reviewer for the following journals: Ocean Science, Estuarine Coastal and Shelf Science, Ecological Modelling, Climate Research, Journal of Environmental Management, Environmental Modelling and Assessment.
