How does the brain represent, store, and retrieve past experiences in memory?

 

I am a PhD student in the Phelps Lab at Harvard University supported by a National Science Foundation (NSF) fellowship. My research focuses on understanding the neurobiological underpinnings of memory.

I use modern neuroimaging techniques to investigate how representations of memory during encoding and consolidation processes evolve over time given subsequent retrieval and reconsolidation processes. By studying these mechanisms, I aim to shed light on why they so often go awry in progressive neurological pathologies such as Alzheimer’s disease.

Post-encoding cognitive load

2020 – present

Recently, we identified step-wise reduction in hippocampal activity as a function of increases in cognitive load during a working memory task. We plan to use this intervention to disrupt the encoding and consolidation processes and investigate its neural and behavioral consequences across time.

 

We examine the extent to which entrainment via audio-visual stimuli may lead to inter-subject neural synchrony, and whether social and affective factors influence such synchrony. We employ EEG, naturalistic video stimuli, and a within-subject group design.
