Dimitris Tzionas

Assistant Professor

University of Amsterdam


I am an Assistant Professor for 3D Computer Vision at the University of Amsterdam (UvA) since June 2022.

     Motivated & Creative students can contact me by following these instructions.

Earlier, I was a Research Scientist at the Perceiving Systems (PS) department at MPI for Intelligent Systems (MPI-IS).

Even earlier, I was a PostDoc at the same department (PS @ MPI-IS) advised by Michael Black.

I received a PhD from the University of Bonn for my thesis on Hand-Object Interaction advised by Juergen Gall.

I studied Electrical & Computer Engineering at the Aristotle University of Thessaloniki advised by L. Hadjileontiadis.


Research Direction

I conduct research on the intersection of Computer Vision (CV), Computer Graphics (CG) and Machine Learning (ML). My motivation is to understand and model how people look, move and interact with the physical world and with each other to perform tasks.

This involves (1) accurately “capturing” real people and their whole-body interactions with scenes and objects, (2) modeling their shape, pose and interaction relationships, (3) applying these models to reconstruct real-life actions in 3D/4D, and (4) using these models to generate realistic interacting avatars in 3D/4D.

Potential applications include Ambient Intelligence, Virtual Assistants, Human-Computer/Robot Interaction, Mixed Reality and the “Metaverse”.

The long-term goal is to develop human-centered AI that perceives humans, understands their behavior and helps them to achieve their goals.
