Erich Liang
I am a 3rd year Ph.D. student in Computer Science at Princeton University, advised by Prof. Jia Deng. My research interests include 3D vision, robotics, and graphics. I enjoy working on problems that help us combine geometric constraints with large-scale data to build 3D algorithms and robots capable of mirroing how humans perceive the world. Topics I've explored include:
- Imaging & Camera Calibration: lens optics and calibration for mapping 3D onto 2D images.
- 3D Reconstruction & Geometry: mesh reconstruction, inverse graphics, SLAM, NeRFs, 3DGS.
- Generative 3D Models: view-based 3D scene generation, occlusion reasoning, diffusion.
- Benchmarks & Evaluation: benchmarks, datasets, and metrics to train and evaluate 3D algorithms.
Previously, I served as a research assistant at BAIR, collaborating with Prof. Ren Ng and Prof. Avideh Zakhor. I graduated with a B.S. in Mathematics and Computer Science from Caltech, where I worked closely with Prof. Katie Bouman and Prof. Adam Wierman. I have also interned at companies such as Amazon, Meta, Bloomberg, and Microsoft.

Dear prospective collaborators: Click here for information.
Thank you for your interest in working with me! I am always looking for potential collaborators and motivated students to work together on research.
For collaborators: Please send me an email with a brief description of the research topics or ideas you would like to collaborate on.
For Princeton students: If you're already at Princeton and interested in research opportunities (IW, Senior thesis, undergraduate research), please email me with your resume, transcript, and a brief description of your research interests.
For non-Princeton students: Most research I conduct does not require in-person presence; however, granting access to campus compute and file access may be difficult. If you are interested in remote collaboration, and have access to your own compute needed for your research interests, please reach out via email.
