I am a research scientist at Google Zurich, where I work on computer vision and machine learning with the focus on Neural Rendering and Generative Neural Networks. Previously, I was a postdoctoral researcher in the Visual Computing and AI department of Prof. Christian Theobalt at Max-Planck Institute for Informatics, where I worked on photorealistic rendering of humans and human-centric vision. I obtained my PhD under Prof. Didier Stricker at German Research Center for Artificial Intelligence (DFKI) Kaiserslautern on the topic of 3D shape representations for learning. I got my bachelor and masters degrees in the subject of Computer Science and Engineering from the Indian Institute of Technology Kharagpur, India (IIT Kharagpur). |
