Stéphane Rehel

I am a PhD student supervised by Géraldine Rauchs (Inserm U1077 NIMH) and Gaël Chételat.

In the AGEWELL project, I am exploring the relationships between sleep, ageing and Alzheimer’s disease biomarkers, focusing more precisely on how these relationships are modulated by cognitive reserve and psycho-affective factors such as anxiety and depression.

Claire André

I am a PhD student under the supervision of Géraldine Rauchs (Inserm U1077 unit) and Gaël since autumn 2015.

My project aims to better understand the relationships between sleep quality, the risk of cognitive decline, and Alzheimer’s disease biomarkers in multimodal neuroimaging.

I also took part in data acquisition and the everyday life of the protocole, and put electrodes on a lot of heads ! Sleep well, age well !​

Siya Sherif

I am a Research Engineer at Gael’s Team. I obtained Five year integrated Master’s in Physics from the University of Mysore (India) and carried out my doctoral studies at the IMDEA ( Madrid Institute of Advanced Studies) and Universidad Autónoma de Madrid (Spain).

Before joining Cyceron, I was a Research Scientist at the Neuroimaging department of the National Brain Research Centre (India). At present, I am working on the multimodal neuroimaging analysis of Alzheimer’s Disease.

Alexandre Bejanin

Alex joined Chetelat’s Lab in 2016. His research focused on the similarites and diffrences in pathophysiological processes between Alzheimer’s disease and frontotemporal dementia through multimodal neuroimaging.

His academic background includes a PhD at the University of Caen Normandy, under DR. Béatrice Desgranges’s supervision, on social cognition in semantic dementia.

In 2015-2016, he worked with DR. Gil Rabinovici as a postdoctoral researcher, at University of California San Francisco (UCSF), on tau imaging in distinct neurodegenerative disorders and longitudinal metebolic in frontotemporal dementia

Clémence Tomadesso

Clémence has been in the lab since 2012 and obtained her doctorate degree in 2018. Her project assessed the links between brain alterations and cognition in patients with Mild Cognitive Impairment.

She helped in many aspect of the 2 projects of the team :volunteer’s recruitment, data acquisition, quality check, statistical analyses and educational support for students.

Eider Arenaza Urquijo

Eider is interested in the neural underpinnings of normal cognition in the setting of Alzheimer’s disease.

Her research notably focused on how lifestyle factors (e.g., cognitive, physical and social engagement) influence brain structure and function, relate to Alzheimer’s disease pathological processes and interact with genectic risk.

Justine Mutlu

Justine Mutlu joined the IMAP team in 2012 to obtain her PhD.

Her research work focused on better understanding the links between resting state functional connectivity and atrophy, hypometabolism and amyloid burdern in Alzheimer’s disease.

The rest is not silence!

Renaud La Joie

Renaud initially joined the lab in 2008 for a 6-month internship, however, found himself staying involved in the lab for several years to complete both a Master’s degree and a PhD.

Renaud worked extensively with high-resolution MRI data to assess hippocampal subfields, helped implement Glorbetapir-PET in the lab to measure amyloid deposition, and played with multimodal imaging to study neurodegenerative processes and their relationships to cognitive deficits.


After his defence, Renaud moved to the Bay Area, where he’s been a post-doctoral fellow with Bill Jagust at UC Berkeley, and with Gil Rabinovici at UC San Francisco.

In spite of the distance and time difference, Renaud has kept collaborating with Chetelat’s lab on a regular basis.​

Audrey Perrotin

Audrey was working as an Engineer in the Gael’s team from 2009 to 2015 –before having to leave for others places…


She was especially involved in the IMAP project by managing and coordinating activities between the IMAP members and with associated teams.

She has kept on some scientific collaborations with the team.

She is particularly interested in studying subjective cognition in AD and how it changes in the course of the pathology, from the subjective cognitive decline (SCD, for more details see the SCD section of the project) at early stages, to anosognosia at later stages (MCI and AD dementia).


Neuropsychology and multimodal neuroimaging from the IMAP program offer great means to address these research questions. A pretty long story with subjective memory since it was also the research topic of my PhD (University of Tours, France) and postdoc (University of California, Berkeley, US).​
