During the first semester of my Masters, I did a research project as part of the Fish Ecology advanced course supervised by  Jolle Jolles and Jasminca Behrmann-Godel. I was interested in the role of individual behavioural types of three-spined stickleback and their effects on individual learning capabilities. Together with another masters student I set-up an experiment with 60 sticklebacks that we tested on some classic personality assays and association and reversal learning tasks. It was a great experience for me and I learned important new methods that are important to run a solid and controlled behavioural experiment.
