Songyou Peng (彭崧猷)

I am a PhD student at ETH Zurich and Max Planck Institute for Intelligent Systems as part of Max Planck ETH Center for Learning Systems. I am co-supervised by Prof. Marc Pollefeys and Prof. Andreas Geiger. I am currently working at Autonomous Vision Group (AVG) at MPI Tubingen.

I completed an Erasmus Mundus Masters in Computer Vision and Robotics (VIBOT) with distinction. During the master, I was fortunate to be supervised by Prof. Daniel Cremers at Technical University of Munich for my thesis and work with Prof. Peter Sturm at INRIA Grenoble for two summers. Before this, I obtained a Bachelors in Automation at Xi'an Jiaotong University.

Before my PhD, I was a research engineer at ADSC and A*STAR in Singapore.
