About & Research

Camille Grasso’s research on subjective time, duration and temporal cognition.

Duration · representation · dynamics

Research interests and current projects

My current research interests focus on how subjective duration is constructed across multiple scales—from how ongoing sensory changes are sampled, to the neural population dynamics that represent them, and the neurochemical signals that may modulate those dynamics. I am particularly interested in how these mechanisms interact to shape temporal judgments and distortions, and how they can be integrated within a common computational framework.

Research trajectory

I defended my PhD in May 2022 at Aix-Marseille University, where my work focused on the representation of temporal order in relation to the mental timeline: the idea that temporal order can be mapped onto a left–right spatial axis. Drawing on theoretical frameworks such as neural reuse and Hebbian learning, I investigated the functional role of the sensorimotor system in temporal cognition.

To address this question, I developed experimental protocols using movement initiation times, mouse tracking and eye tracking, across laboratory and large-scale online studies involving more than a thousand participants in total. Overall, my PhD research suggested that the sensorimotor system actively contributes to how we represent and process temporal order.

This work led me to look more closely at what the mental timeline can—and cannot—tell us about how time is represented. At NeuroSpin, I joined Virginie van Wassenhove’s group to study duration within the EXPERIENCE Project. Together, we developed studies combining virtual reality and EEG to examine how spatial context shapes subjective duration, and behavioural and neural measures to investigate how durations are represented.

In September 2025, I joined the Laboratoire de Psychologie et NeuroCognition, working with Nathan Faivre on the VOLTA project. Since June 2026, I have pursued this work through MIND, my Marie Skłodowska-Curie Actions Global Postdoctoral Fellowship. MIND brings together behavioural temporal judgments, intracranial electrophysiology and voltammetry to investigate how neural and dopamine dynamics relate to the duration of conscious experience. I am currently based in the Kishida Lab at Wake Forest University School of Medicine, where I am training in human voltammetry.

In parallel, I’ve also had the chance to join a project in the Kishida Lab that I’m particularly excited about: studying neurochemical dynamics during music listening. Working with the team, I am developing encoding models to explore whether the acoustic and rhythmic structure of music helps predict moment-to-moment dopamine fluctuations, with further questions about the contribution of musical surprise and uncertainty.

More broadly, my goal is to develop an integrative research programme connecting cognitive, electrophysiological and electrochemical levels of explanation to understand how we perceive, feel and represent duration. In the longer term, I hope to extend this work to questions about temporal cognition in conditions such as Parkinson’s disease, schizophrenia and ADHD.

I love the collective side of research: discussing a puzzling result, learning a new method from a colleague, or working out how to turn an idea into an experiment. There is still so much I want to learn, and I’m always happy to talk science—please feel free to get in touch.
