In the middle of the rollercoaster winter 2020-21, Arthur joined the mouse love song adventure via EPFL’s Life Science Engineering MSc programme. He courageously embarked on a project developing an AI-based pipeline for the analysis of mouse behavioural modes. Many video meetings, code wrestling and one day of in-person visit later, Arthur closed the loop from raw data to a report and successfully completed his “remote lab immersion” project. It was a joy to work with him as he ironed out the kinks of an exciting new type of behavioural analysis, and to introduce him to the wonders and headaches of neuroscience research!
