Maëlle Botton

As a psychologist specializing in neuropsychology since 2015, I joined the team of Silver Sante Study in November 2016. As part of this study, I intervene at different stages over the candidates’ journey: from their initial interview and evaluation of global cognitive functioning to their complete neuropsychological assessment. In addition, I use my clinical skills to create a trusting relationship with the subjects throughout these stages.

Stéphanie Egret

I have been part of the team for over 7 years as a neuropsychologist. I take part in the passing of the neuropsychological reports and the original tests in the framework of two research projects : the IMAP (Longitudinal Study in Multimodal Imaging of Alzheimer’s Disease at an Early Stage) and the Silver Health Study, a European study on aging well.

Anne Chocat

I am a medical biologist from Caen, with a liberal and hospitable experience. During my postgraduate training, I felt the relevance of a therapeutic approach through meditation and mindfulness (MBSR courses – MBCI certificate -Mindfulness Based on Compassion and Insight-, Medicine Meditation and Neuroscience). In order to contribute to the scientific recognition of all the benefits of meditation, I joined the Gaël Chetelat team as a co-investigator in the Age-Well study (I am the non-geek of team).

Eglantine Ferrand-Devouge

I am a general practitioner and I am interested in the impact of the mind on the body. I validated a master’s degree in neuroscience and cognitive psychology. I am an investigative doctor in Cyceron since November 2016, for the study Age-Well.

- Neuroimaging Staff -

Brigitte Landeau

I am engineer in developing applications in our lab and mainly in Gaël’s team since 2008. I implement new innovative methods of processing and analysis in multi modal neuroimaging, mainly in resting-state fMRI. I study the alteration of functional connectivity at rest and links with atrophy, hypometabolism, and amyloid deposits in Alzheimer’s disease. I am responsible for training members of the unit to these techniques. I interact with common services in Imaging and Computer of GIP Cyceron.

Florence Mezenge

I’m working as a technical Researcher Gael’s INSERM U1237 team since 2002. My main role is to cooordinate the technical aspects of both IMAP and AGEWELL studies. I am also responsible for the acquisition of the imaging data, including both MRI and PET scans. I am in interaction with the neuroimaging platform of Cyceron and work in close interaction with Brigitte Landeau, for the developement of neuroimaging data processing techniques.

Valentin Ourry

After a formation in biology, i obtained a master of research in Neurosciences. Then, I joined the  team in 2016 to work as engineer. I investigate the effects of lifestyle on cognitively normal older adults and pre-clinical Alzheimer’s disease, using multimodal neuroimaging.

Not all the secrets of the brain are still discovered, that’s exciting!

Gwendoline Le Du

I am working as a research assistant in Gaël’s team since May 2017. I am working on IMAP and AGEWELL projects. My main duties are the recruitment of participants and the data collection.

Eider Arenaza Urquijo

I’m interested in the neural underpinnings of normal cognition in the setting of Alzheimer’s disease. My research notably focuses 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 genetic risk.  

Robin De Flores

After two internships in the lab (M1 and M2), I completed my PhD under the direction of Gael Chételat. My research mainly focuses on the hippocampal subfields alterations (structural and functional) in AD and normal aging.

Alexandre Bejanin

I joined the Chetelat’s Lab in 2016. My research focus on the similarities and differences in pathophysiological processes between Alzheimer’s disease and frontotemporal dementia through multimodal neuroimaging. My academic background includes a PhD at the University of Caen Normandy, under Dr. Béatrice Desgranges supervision, about social cognition in semantic dementia. In 2015-2016, I worked with Dr. Gil Rabinovici as postdoctoral researcher, at University of California San Francisco (UCSF), about tau imaging in distinct neurodegenerative disorders and longitudinal metabolic changes in frontotemporal dementia.

Clémence Tomadesso

I am in the lab since 2012 and PhD student since 2014. My project assess links between brain alterations and cognition in patients with memory loss named Mild Cognitive Impairment. I provide my help for many aspects of the 2 projects of the team : volunteer’s recruitment, data acquisition, quality check, statistical analyses and educational support of students.

Inès Moulinet

Hi, my name is Inès Moulinet. I’m currently doing a 6 month internship entitled « cerebral correlates of anxiety in healthy and pathological aging » based on MRI and PET imaging, using IMAP data. I’m also helping on the medit-ageing project.

Hi, my name is Elizabeth Kuhn. I’m currently doing a 6 month internship entitled « cerebral correlates of memory complaint and anosognosia at different stages of Alzheimer’s disease » based on MRI and PET imaging, using IMAP data. I’m also helping on the medit-ageing project.

- Sleep team -
I am collaborating with Gaël for several years. I am a sleep scientist in the research unit NIMH (Inserm U1077). I am interested in the role of sleep in memory consolidation and the impact of sleep disturbances on structural, functional and molecular brain alterations. In the AGEWELL project, I am responsible of sleep examinations and I co-supervise with Gaël two PhD students (Claire André & Stéphane Rehel). We work in close interaction with the Sleep department of the University Hospital and with the neuroimaging experts of Gaël’s team.
Geraldine Rauchs
Sleep team leader

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

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.

Justine Mutlu

I am Justine Mutlu; I have joined the IMAP team since 2012 to realize my thesis. My research work is focused on understanding the links between resting state functional connectivity and atrophy, hypometabolism and amyloid burden in Alzheimer’s disease. The rest is not silence!

Julie Gonneaud

Renaud La Joie

I initially joined the lab in early 2008 for a 6-month internship, however, found himself staying involved in the lab for several years to conduct both his Master’s degree and PhD. Renaud worked extensively with high-resolution MRI data to assess hippocampal subfields, helped implement Florbetapir-PET in the lab to measure amyloid deposition, and played with multimodal imaging to study neurodegenerative process and their relationships to cognitive deficits. After his defense, 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 differences, Renaud has kept collaborating with the Chetelat lab on a regular basis. »

Audrey Perrotin

I was working as an Engineer in the Gael’s team from 2009 to 2015 –before having to leave for others places… 🙁
I was especially involved in the IMAP project by managing and coordinating activities between the IMAP members and with associated teams.

I have the chance to keep on some scientific collaborations with the team. I’m 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).
