My PhD research is a continuation of the work carried out during my MSc, investigating the neural basis of value-based choice. Specifically, I am investigating how individuals integrate different variables such as confidence, memories and knowledge about third parties to derive composite values to different options and proceed to compare options with one another. I am exploring the biological basis of these processes using state-of-the-art rapid event-related fMRI in combination with computational models in an attempt to better understand the underlying neural mechanisms.
