Phd Student

After completing a master’s degree in clinical psychology and neuropsychology, I joined the team as a PhD student under the supervision of Dr. Géraldine Rauchs and Dr. Claire André. My research focuses on REM sleep microstates (tonic and phasic) in older adults and their links with Alzheimer’s disease biomarkers, cognitive functioning and psycho-affective symptoms. Combining sleep EEG microstate analysis with multimodal neuroimaging, I investigate whether alterations in these microstates are associated with early Alzheimer’s-related brain changes and whether they can predict longitudinal cognitive and psycho-affective trajectories. Ultimately, this work aims to clarify the role of REM sleep microstructure in the earliest stages of Alzheimer’s disease.
