Software engineer at Ecopath International Initiative Research Association (Earth sciences; Environmental sciences)

Barcelona, Spain

Jeroen Steenbeek is a classically trained software engineer with over 25 years of experience in industrial and academic software developments. He is a core programmer of the Ecopath with Ecosim (EwE) food web modelling approach since 2005 and still loves his job. His main research interest is solving ecosystem-modeling challenges by simplifying the interactions between science and technology using state-of-the-art computing paradigms, programming languages, GIS, and serious gaming. He participates in ecosystem modeling research projects around the globe, and has authored over 60 research papers in scientific journals. Jeroen holds an MSc in GIS, and recently started a PhD in marine ecology to address the global need to better fit and validate spatial-temporal marine ecosystem models for policy uptake.
