Ethan Murphy graduated with a BSc. in Neuroscience (First Class Honours) from Trinity College Dublin. He is currently enrolled in the MSc in Cognitive Science at University College Dublin. Ethan’s long term goal is to complete a PhD in Cognitive Neuroscience. While interning with the Gillan Lab, Ethan will be working with data from the Cannon Blast game in the neureka app. This game assesses model-based and model-free planning, two key reinforcement based learning phenomena that are linked to real world functional impairments associated with compulsivity.
