- We have a new paper in the Journal of Neuroscience on how single episodes of reward experience are represented in the brain and how they can affect later decision making: Wimmer & Büchel, 2016.
- Aaron Bornstein and I organized a workshop at COSYNE in 2015 on "The role(s) of the hippocampus in decisions for reward," which the speakers and participants made a great success.
- My research is focused on the cognitive and neural systems underlying learning and decision making.
- Currently, I am a post-doc with Prof. Russ Poldrack at Stanford University.
- I secured funding from the German research foundation (DFG) to investigate a project on the influence of temporal spacing on the cognitive and neural systems supporting feedback learning.
- Recently, I was a post-doctoral researcher with Prof. Christian Büchel at the University Medical Center Hamburg-Eppendorf in Hamburg, Germany.
- My doctoral research was conducted in the Psychology Department of Columbia University with Prof. Daphna Shohamy.
