Welcome to the
O'BRAIN Lab
At O'Brain Lab, we investigate the neural mechanisms underlying decision-making, eating behavior, and obesity using advanced neuroimaging and computational neuroscience approaches.
The brain shapes what and how we eat. Yet in the same food environment, some people develop unhealthy eating patterns while others do not - and many struggle to stick to their dietary goals. Our lab studies how brain processes like learning, decision-making, and perception influence eating behaviour. Using cutting-edge neuroscience methods, we aim to uncover why eating goes wrong - and how this knowledge can inform interventions for conditions such as obesity that truly work.
Our Research
What We Investigate
Our research aims to understand the neural and cognitive mechanisms underlying eating behavior and obesity
Neural Mechanisms of Decision-Making
We investigate how the brain processes food-related decisions and how these mechanisms differ in individuals with obesity.
Eating Behavior & Self-Control
Understanding why dietary goals are difficult to maintain and how brain function relates to eating behaviors.
Computational Neuroscience
Using advanced computational models to understand cognitive processes underlying food choice and consumption.
Neuroimaging & Brain Plasticity
Employing fMRI, EEG, and other techniques to study brain structure, function, and plasticity related to eating behavior.

Participate in Our Studies
We are recruiting participants for exciting research projects. Your participation helps advance our understanding of brain function and eating behavior.
LUMINA Project
Beyond the common symptoms induced by cancer treatments commonly experienced (e.g., nausea, fatigue…), some symptoms can persist even months after the end of their treatment. Many survivors have reported dizziness, difficulty in attention and concentration, or brief loss of memory. All of these relate to the brain and to what is called 'cognitive functions'. This project aims to explore how brain function is affected after breast cancer and how these changes impact survivors' daily lives compared to people without cancer.

MARVEL Project
Beyond the simple act of choosing what to eat, our food decisions are influenced by how we perceive the value of different snacks and by the environment we are in when making these choices. This project seeks to understand how people evaluate common and familiar snack foods and how varying contexts might shape eating behavior. By studying these patterns, we aim to gain insights into how everyday food choices are formed and what factors guide them.
