Dr Rémy Lachelin

Post-doctoral Researcher

My current research interest is understanding sequence space synaesthesia as well as the interplay between perception and long term memory. I worked on numerical cognition and multilingualism during my PhD.

Dr Rémy Lachelin is a postdoctoral researcher in the Faculty of Psychology at UniDistance Suisse since 2025. His research focuses on spatal representations of sequences, perception and memory

He completed his PhD at the University of Luxembourg in 2024, where he investigated the lexical and semantic representation of numbers in German and French bilinguals. In his current postdoctoral position he works on sequence space synaesthesia and the interplay between perceptiona and memory.
