My research interests focus on visual localization, 3D/4D reconstruction, and neural scene representations and understanding. I am also broadly interested in object-level perception, egocentric vision, and developing algorithms for robotics and mixed reality applications. Please feel free to drop me an email if you would like to discuss research ideas.

Recent deep learning have boosted the performance of visual SLAM. Methods like DROID-SLAM and DPVO rely on large-scale synthetic data to learn correspondences and camera poses, but they require ground-truth supervision, which limits the scale of available training data. In this project, we explore reducing the supervision signal to eventually develop a self-supervised visual SLAM system trainable on any casual video.

Preferred Requirements:

• Strong research motivation with a focus on achieving publication.
• Strong background in 3D computer vision and multi-view geometry; knowledge of SLAM is a plus.
• Proficiency in Python and PyTorch.

If you are interested, please contact me via email with your CV and transcript.
