Our research aims at understanding how we remember and forget about our past experiences, and the neurocognitive processes supporting these memory dynamics. One fundamental assumption of this research is that memory plays a central role in shaping our preferences and beliefs, and in guiding our judgments and behaviors. Our research aims to elucidate how motivational, emotional and cognitive processes may influence memory processes. Of particular interests, we consider sleep as an indispensable component to complete our understanding of memory.

We mostly employ EEG, behavioral and online studies in our research. If you are interested in learning more about us and about our research, please find our lab members and publications here.
