Kevin Qu

I am a 1st-year PhD student in the Computer Vision and Learning Group (VLG) at ETH Zürich, advised by Prof. Siyu Tang.

Before I started my PhD, I obtained my Master's in Robotics, Systems and Control at ETH Zürich. During my Master's, I was a Visiting Student Researcher at Stanford University in the Gradient Spaces Lab, advised by Prof. Iro Armeni, working on 3D articulated object modeling. I was also a research intern at the Microsoft Spatial AI Lab under Prof. Marc Pollefeys, where I focused on spatial video understanding with Vision-Language Models (VLMs), and a research assistant at Prof. Konrad Schindler's PRS Lab at ETH, working on diffusion models for dense prediction tasks.

Before that, I obtained a Bachelor's in Electrical and Computer Engineering from the Technical University of Munich. During this time, I was a research intern at the University of Victoria under Prof. Lin Cai, working on communication networks for autonomous driving, and spent a semester abroad at the University of Edinburgh.
