Nikolaos Athanasiou

Ph.D. student at the Max Planck Institute for Intelligent Systems, Perceiving Systems department.

My research focuses on exploring and analyzing the underlying causes behind human movement, combining language with human movement to understand emotions, goals, and plans in multimodal environments.

Supervised by Michael J. Black and Gül Varol, my research aims to understand the intricate details of human movement and its underlying causes.
