- With Yunzhe Liu at the Max Planck UCL Centre, we have a new preprint out on my first MEG investigation of sequenceness (replay) in humans (bioRxiv 2019). We find the memory decisions are based on rapid compressed replay of original experiences.
- From my work with Christian Büchel, we published a paper on the role of the OFC in learning predictions of distant states in Nature Communications (2019).
- From my work with Russ Poldrack funded by the DFG, we published a paper on the effects of temporal spacing on reward learning in the Journal of Neuroscience. In addition to multivariate fMRI results, we find that "spaced" training establishes longer-lasting value associations, while typical "massed" single-session learning is related to working memory capacity.
- My research is focused on the cognitive and neural systems underlying learning and decision making.
- Currently, I am based with Prof. Ray Dolan at the Max Planck UCL Centre for Computational Psychiatry and Ageing.
- At Stanford University with Prof. Russ Poldrack, I began work supported by the German research foundation (DFG) to investigate the influence of temporal spacing on the cognitive and neural systems supporting feedback learning.
- Previously, 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.
