Michael Zollhöfer works as a Post Doctoral Researcher in computer vision and computer graphics at the Graphics, Vision & Video Group headed by Prof. Christian Theobalt. He received his PhD from the University of Erlangen-Nuremberg for his work on real-time non-rigid reconstruction.

During his PhD, he developed a data-parallel variant of Gauss-Newton that exploits modern graphics hardware. This non-linear solver enables the real-time solution of a wide range of computer graphics and computer vision problems, such as non-rigid tracking, shading-based refinement, intrinsic decomposition, bundle adjustment, multi-projection mapping and facial reenactment. His GPU solver is also the back end of a domain specific optimization language. In addition, his research interests include: face tracking from monocular video, high-quality inverse rendering, real-time hand-object tracking and template-free deformable reconstruction.

He is reviewing for the top journals and conferences:
