About Me




Hi! I’m Balamurugan Thambiraja, presently pursuing a PhD at the Neural Capture and Synthesis group of Prof. Justus Thies at the Max-Planck Institute for Intelligent Systems, Germany. During my Ph.D., I'm collobrating with Darren Cosker and Sadegh Aliakbarian from Mesh Labs, Microsoft, Cambrdige.

In my Ph.D., I am exploring ways to leverage seq2seq and foundational models for synthesizing human motion and its underlying dynamics. Recently, I have been working with diffusion models and large language models for motion synthesis and editing, aiming to enhance the realism, controllability and generalization to in-the-wild scenarios.

Before the PhD, I did a Masters in Informatics at TUM, Germany, where I worked on human modelling and sign language synthesis at the Visual Computing and Artificial Intelligence group of Prof. Matthias Niessner. Before that, I did my Bachelors in Electrical and Electronics Engineering at Kumaraguru College of Technology, Coimbatore, India.
