I was an intern for the Ecopath Research and Development Consortium based at the Scottish Association for Marine Science (SAMS) near Oban. The aims of the internship were to work on and develop the Ecopath with Ecosim (EwE) software. I implemented a Stepwise Fitting Procedure Plug-in for automated fitting of EwE models. A paper was published in the SoftwareX journal (March 2016) Available online. This internship was funded by the SICSA Postgraduate Industry Internship Programme.
