Géraldine Rauchs

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.

Géraldine Poisnel

Leader of the work-package management of EU-funded Silver Santé Study and project manager on a large longitudinal multimodal neuroimaging multicentre project, I have an ideal background as I graduated in Project Management and previously worked on neuroimaging biomarkers and Alzheimer’s Disease in Pharma industry and during my PhD in Biology-Pharmacology.

Adept of the multitasking, I work also on the biological aspects with a special focus to uncover mechanisms underlying age-related changes in brain using blood markers.

Robin De Flores

I am interested in characterizing medial temporal lobe (MTL) alterations in normal and pathological aging. More precisely, I use and develop neuroimaging tools, including structural and functional MRI, to better understand how MTL structures and networks are affected by different conditions.

I did my PhD, entitled « Structural, functional and molecular alterations of hippocampal subfields and their networks in normal aging and Alzheimer’s disease », under the supervision of Gaël Chételat from 2013 to 2016.

I then moved to Philadelphia for a two-year postdoc to continue exploring the MTL with Dr David Wolk and Dr Paul Yushkevich. I came back to Caen in january 2020, riding aa seahorse.

Julie Gonneaud

After a PhD in Psychology under the supervision of Dr Béatrice Desgrandes (Inserm U923, Caen), a first postodc in Dr Gaël Chetelat’s lab and a second postdocoral experience in Dr Sylvia Villeneuve’s lab (Douglas Research Institue/MCGill University; Montreal, Canada), I returned to the Chetelat’s lab in November 2019 as a posdoctoral researcher.

 

I use mutlimodal neuroimaging to further understand the physiopathology of Alzheimer’s disease (AD) and the factors that could influence the risk of developing AD in cognitively unimpaired individuals.

 

My work will mainly focus on the influence of lifestyle factors (e.g. cognitive, physucal and social activity, diet) on AD brain and cognitive markers and how these factors can interact with other risk factors (e.g. sex, genetics) to modulate AD risk.

Matthieu Vanhoutte

I have a background in physics and biomedical engineering. I first worked as an embedded critical software architect and designer, which allowed me to complete software & sytem skills needed on any high complexity project. As a research enginer in neuroimaging,

I improved my knowledge of PET/MRI imaging and my skills in developing imaging analysis methods in the context of neurodegenerative diseases. Eager to acquire further expersite in these fields, I did a PhD on early onset Alzheimer’s disease Neurolmaging, that I obtained in December 2018, and started a Postdoctoral fellowship in Gaël Chetelat’s team inFebruary 2019.

As a postdoc, I am working on the optimization of early-phase Florbetepir PET imaging as a marker of neurodegeneration

Caitlin Ware

I work as a research engineer for Age-Well. My main role is to plan, organize, and help facilitate the English learning intervention for Silver Santé study. I am also currently writing my PhD on the subject of bilingualism and Alzheimer’s disease at the University of Paris VII Diderot.


 I conduct research on the psychological and cognitive effects of foreign language learning in older adults. My interests are psychoanalysis, cognitive reserve, and the psychological factors involved in learning a second language.

- Research -PhD Students

Inès Moulinet

Hi, my name is Inès Moulinet. I’m PhD student and my project aims at better understanding psycho-affective factors, in normal and pathological ageing (Alzheimer’s disease), using IMAP multimodal data.

I’m also helping with the data acquisition for the Medit-Ageing project.

Elizabeth Kuhn

Since 2017, I’ve been a Phd Student under the supervision of DR Gael Chetelat and the co-supervision of Pr Vincent de la Sayette. My research interest focuses on the evolution of awareness of one’s own cognitive abilities in Alzheimer’s clinical syndrome.

I’m interested in the cerebral substrates of subjective cognitive decline (SCD) or self-awareness, and their links to objective cognitive decline at different stages of the cognitive spectrum.

Edelweiss Touron

I joined the Chetelat’s lab in 2017 to do an intership during my Master’s degree in Neurosciences and Behavioural sciences. I am currently a PhD Student supervised by Gaël Chételat and Géraldine Poisnel (2018-2021).

The aim of my project is to better understand the links between subclinical depressive symptoms and neuroimaging and blood biomarkers in ageing, using the Medit-Ageing data.

Sophie Dautricourt

I am a neurologist with a special interest in cognitive disorders and neurodegenerative diseases and currently a Phd student in Gaël Chetelat lab, working in the Silver Sante Study.

My research lies in understanding how brain network connectivity is affected in Alzheimer’s disease. I am studying the changes in anterior temporal and posterior medial hippocampal network connectivity in Alzheimer’s disease patients. I am also investigating if specific brain network connectivity pattenrs are associated with an increased risk of Alzheimer’s disease in ageing people and how they are influenced by lifestyle and psycho-affective factors.

Finally, I aim to investigate how a mental training based on stress and emotions regulation, through meditation practice, could influence cerebral connectivity pattern and potentially reduce the risk of Alzheimer’s disease.

Valentin Ourry

I join the team in 2016 as a research assistant, I worked on lifestyle and neuroimaging. I also took part in data acquisition. In 2018, I started a PhD under the supervision of Géraldine Rauchs (Inserm U1077 NIMH) and I work on sleep, lifestyle and multimodal neuroimaging in the context of aging.


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

Cassandre Palix

Hi, I’m a PhD student under the supervisionof Géraldine Poisnel and Gaël Chételat (UMR-S 1237).

My really cool thesis project aims atunderstandingthe impact of mental training (meditation and English learning) on the allostatic load(a cumulative measure of different blood biomarkers), an index of successful aging! I also take part in data acquisition.

Francesca Felisatti

I joined the team in 2018 as a research asistant in the Age-well project, and I am now doing my PhD on the interactuins between lifestyle factors (e.g., congitive, physical and social activities) and brain markers of Alzheimer’s disease.

My interest lies in understanding how modifiable factors such as envrionment and lifestyle impact brain structure and function, and how they can be targeted to delay cognitive decline in healthy aging as well as in neurodegenerative diseases.

Pierre Champetier

I am a PhD student under the supervision of Géraldine Rauchs (Inserm U1077 NIMH)since spetembre 2019.

I want to see if meditation practice can help to preserve sleep quality, and if this can help to prevent cognitive and brain alterations due to ageing.
