Maolin Gao (高茂林)

I am a Ph.D. student at TUM CVAI Lab with Prof. Daniel Cremers, working on computer vision, graphics and optimisation. I was a visiting scholar at the Geometric Computing Lab at Stanford University headed by Prof. Leonidas J. Guibas in the summer 2024.

My current research centers on the intersection of geometry and learning, aiming to enhance both human and machine understanding of 2D and 3D data.

Prior to my move to Munich, I was a computer vision engineer on ADAS Vision systems at Bosch Stuttgart. Prior to this, I obtained my Master's degree at TUM Department of Electrical Engineer and Information Technology, where I wrote my master thesis on Blind Deconvolution under the supervision of Dr. Michael Hirsch, Prof. Philipp Hennig and Prof. Bernhard Schölkopf in MPI-IS Tübingen. I obtained my Bachelor in Physics at Tongji University in Shanghai, during which I spent a year at TUM and a summer at RWTH Aachen.
