Sofia Saraiva graduated in 2001 from an Environmental Engineering 5 year degree at Instituto Superior Técnico (IST), University of Lisbon (UL) in Lisbon. Her final project was on the study of the primary production dynamics in the Tagus estuary (Portugal) using an ecosystem model. In the same year she started a junior position at the MARETEC (IST) where she worked for several years, on many different projects and topics but always related with ecosystem modelling and biogeochemical cycles of nutrients. As a complement to modelling, Sofia was also participant and responsible for the design, implementation and execution of monitoring programs with automatic acquisition systems including the use of probes, GPS and dataloggers to collect information for model validation. In 2005 she concluded the two years MSc project on the macroalgae activity modelling in Ria de Aveiro (Portugal). A PhD position brought Sofia to the NIOZ in Texel, The Netherlands, in 2008, to study deeply the bivalves and their interaction with the other components of the ecological system. In 2009, Sofia received a PhD grant from the Fundação para a Ciência e a Tecnologia (Portugal) to continue the studies on bivalves, supervised by Prof. Jaap van der Meer (NIOZ), Prof. Bas Kooijman (VU), Prof. Ramiro Neves (IST) and Tânia Sousa (IST). The research goal was to study bivalve population dynamics and quantify their influence on the pelagic system, through the development and use of a modelling tool. This tool is the result of coupling a size-structured population model for bivalves, based on the Dynamic Energy Budgets Theory, with a hydrodynamic and biogeochemical model (MOHID). After, Sofia moved then to Norrköping, Sweden where she worked as a researcher at the research department of the Swedish Meteorological and Hydrological Institute for two years. Her main tasks were to build up future climate projections for the water quality in the Baltic Sea, funded by the BalticAPP project, included in the BONUS program. Since September 2017 Sofia is holding a postdoc position back to Portugal, at MARETEC, Lisbon, funded by an individual postdoc grant awarded by FCT to focus on the ‘Sustainable shellfish production under climate change: Ria de Aveiro and Tagus estuary’.
