Gaël Chételat

I am very proud to lead this fantastic team, to see all the different characters, cultures, backgrounds and functions to form a harmonious entity guided by a common motivation and all working with enthusiasm and energy in the same direction.

– Research | Post-doc –

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 (Valentin Ourry and Pierre Champetier). We work in close interaction with the Sleep department of the University Hospital and with the neuroimaging experts of Gaël’s team.

Anne-Lise Pitel

I have been working on the effect of chronic and heavy alcohol consumption on brain and cognition for almost 20 years. I have significantly contributed to the understanding of the cognitive and brain pathophysiology of alcohol use disorder and Korsakoff’s syndrome.

I now aim at setting-up and testing non-pharmacological intervention protocols to improve cognitive abilities and to favor the reduction of alcohol consumption or abstinence in patients with alcohol use disorder. By joining Gaël’s lab, I plan to extend my investigations to older subjects with alcohol use disorder in order to determine the contribution of alcohol consumption to the development of neurodegenerative diseases.

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’m 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 a seahorse.

Julie Gonneaud

After a PhD in Psychology under the supervision of Dr Béatrice Desgranges (Inserm U923, Caen), a first postdoc in Dr Gaël Chételat’s lab and a second postdoctoral experience in Dr Sylvia Villeneuve’s lab (Douglas Research Institute/McGill University; Montreal, Canada), I returned to Chételat’s lab in November 2019 as a postdoctoral researcher. I use multimodal 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, physical 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.

Daniel Roquet

I aim to disentangle the complexity of the brain changes in dementia and normal ageing and their association with behavioural and cognitive impairments. To achieve this goal, I combined multimodal imaging in a longitudinal approach. I started my post-doctoral research at the University of Strasbourg (ICube laboratory, Integrative multimodal imaging for health Team), focusing on dementia with lewy bodies, before I relocated to the University of Sydney (Frontier Research Clinic, MIND team) where I pursued my research in Frontotemporal dementia and normal ageing. I joined Chételat’s lab in May 2021 as a postdoctoral researcher to investigate the relationship between brain perfusion, amyloid burden and white matter lesions, based on multimodal MRI and PET imaging.

– Research | Phd Student –

Elizabeth Kuhn

Since 2017, I am a PhD student under the supervision of Dr Gaël Chételat 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 during Alzheimer’s clinical syndrome. I am interest in the brain substrates of self-awareness, its links to cognitive decline and the impact of 18-month non-pharmacological interventions based on cognitive training or meditation training on self-awareness.

Edelweiss Touron

I joined the Chételat’s lab since my internships of a master’s degree in neurosciences and behavioural sciences in 2017. 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 and to assess the impact of the 18-month mental training of meditation on depressive symptoms and their different substrates. 

Sophie Dautricourt

I am a neurologist with a special interest in cognitive disorders and neurodegenerative diseases and am currently a PhD student in Gaël Chételat’s lab, working on the Silver Santé Study. My research lies in understanding how brain network connectivity is affected in Alzheimer’s disease. I’m studying the changes in anterior temporal and posterior medial hippocampal network connectivity in Alzheimer’s disease patients. I’m also investigating if specific brain network connectivity patterns 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 mental training based on stress and emotion regulation, through meditation practice, could influence cerebral connectivity patterns and potentially reduce the risk of Alzheimer’s disease.

Valentin Ourry

I joined 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 have been discovered, that’s exciting!

Cassandre Palix

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

My really cool thesis project aims at understanding the 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 assistant in the Age-Well project, and I am now doing my PhD on the interactions between lifestyle factors (e.g., cognitive, physical and social activities) and brain markers of Alzheimer’s disease. My interest lies in understanding how modifiable factors such as environment 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

Since September 2019, I have been a PhD student under the supervision of Géraldine Rauchs (Inserm U1077 NIMH). I would like to see if meditation practice can help to preserve sleep quality, and if this can help to prevent cognitive and brain alterations due to aging.

Sacha Haudry

Hi, I joined the team in 2018 as an intern for my master degree and I am now working as a research assistant before beginning my PhD next year.

My project aims at understanding the impact of a meditation practice on the brain of healthy older adults by measuring its changes in volume, metabolism, amyloid deposits and functional connectivity.

Léa Chauveau

I joined Gaël Chételat’s team during a master 2 internship and will now start a PhD thesis under the supervision of Robin de Flores using Silver Santé Study longitudinal data. This thesis mainly focuses on functional connectivity of medial temporal lobe networks and its links with modifiable life factors and biomarkers of Alzheimer’s disease. It also aims to investigate the effects of both meditation and English practice on this functional integrity and how these potential changes translate from an emotional and cognitive point of view.

Jade Lasserve

I joined the team for my master 2 internship. I am using Silver Santé Study MRI data to distinguish two medial temporal lobe networks. This internship completes my computer science engineering and medical imaging master studies.

Anaïs Hamel

I joined the Chételat’s lab since October 2021 for my PhD thesis under
the supervision of Dr Géraldine Rauchs. I will investigate the impact of meditation practice on sleep quality and memory consolidation in older adults.
Neuroimaging is a totally new field for me, and I will focus my analyses on resting-state functional connectivity. During my thesis, I will be co-supervised by Dr Alison Mary (Université Libre de Bruxelles, Belgium).
