Gerard Derosiere is the principal investigator of our lab. He has held a permanent researcher position at the French National Institute of Health and Medical Research (INSERM) since November 2022, establishing his line of research at the Lyon Research Center for Neuroscience (CRNL) on effort-based decision-making and apathy. Prior to his relocation to Lyon, Gerard dedicated eight years as a postdoctoral researcher in Prof. Julie Duque’s lab at UCLouvain, in Brussels, from 2014 to 2022. During this period, he also undertook short-term research stays in Prof. Paul Cisek’s lab at the University of Montreal in 2015, and in Prof. Rich Ivry's lab at UC Berkeley in 2019. Gerard earned his PhD through an international program between the University of Montpellier in France and the National University of Ireland. Throughout his academic background, he has developed an interest for the interplay between Cognition and Action and for the brain circuits that integrate these processes.

Sarah is a postdoctoral researcher who will join our laboratory in September 2026. Her previous research focused on decision-making in the context of creativity. On our team, she will work on effective connectivity quantification and modulation to explore the role of recurrent circuits between fronto-striatal structures and the motor cortex in effort-based decision-making. Her work will employ a multimodal approach combining computational modeling of decision behavior, brain stimulation techniques, and MRI.

Margaux is a second-year PhD student, funded by a French Ministry PhD grant, which she earned through a selective competition process at the doctoral school in Neuroscience and Cognition (NSCo). Her PhD, co-supervised with Dr. Pierre Vassiliadis, explores the role of oscillatory processes in effort and reward valuation during effort-based decision-making. She applies advanced methods, including hierarchical drift-diffusion modeling, high-density transcranial electrical stimulation for oscillatory modulation, and magnetoencephalography for synchrony quantification.

Bruna is a first-year PhD student holding a double degree in Biomedical Engineering and Neuroscience. She was awarded a prestigious MSCA co-fund fellowship through the ArchiFun network to pursue her doctoral studies. Her PhD, co-supervised with Dr. Franziska Knolle in Munich, investigates the neural and computational bases underlying apathy in schizophrenia and schizotypy. Bruna’s research integrates multimodal neuroimaging, computational modeling of behavior, brain stimulation, and online studies to uncover the mechanisms driving apathy and explore potential ways to alleviate it.

​Miriam is a first-year PhD student employed by the University Hospital (TUM Klinikum rechts der Isar) at the University of Munich (TUM). Her PhD, co-supervised by Dr. Franziska Knolle, investigates the neurobiological mechanisms underlying apathy in individuals with schizophrenia. Miriam’s research combines MRI and computational modeling to identify biomarkers predictive of apathy development as well as design non-invasive brain stimulation protocols for early intervention. She is mostly based in Munich, works remotely with the lab, and will conduct extended research stays in Lyon as part of her co-supervised PhD!

Elie is a fourth-year engineering student in the Computer Science department at INSA Lyon, doing his internship in our laboratory in 2026 and co-supervised by Bruna Carvalho Fernandes (PhD student). He is working on a project entitled "Online-Motives", which intends to develop large-scale online behavioral experiments to investigate the mechanisms underlying decision-making and motivation in the general population.
