Hello, I'm Jiezhi "Stephen" Yang

I am a first year Master’s student in Computational Science Engineering at Harvard University. I received my B.A. in Computer Science and Cognitive Science from UC Berkeley, where I graduated from the EECS Honors Program with high distinction.

I am interested in computer vision, especially 3D vision and Neural Radiance Field (NeRF). At Berkeley, I was fortunate to work at RISE and BAIR Lab under Prof. Joseph E. Gonzalez and Trevor Darrell, with Ph.D. candidate Charles Packer, Lisa Dunlap, and Alvin Wan.

I am open to research or internship opportunities. Please contact me at stephenyang[AT]berkeley[DOT]edu.

Publications

CARFF: Conditional Auto-encoded Radiance Field for 3D Scene Forecasting

Jiezhi Yang, Khushi Desai, Charles Packer, Harshil Bhatia, Nicholas Rhinehart, Rowan McAllister, Joseph Gonzalez

Submitted to CVPR 2024

We predict future 3D scenes given past 2D observations, such as 2D ego-centric image in autonomous driving settings.

May - August 2021

Researched on modeling Radar, LIDAR, and camera data for infrastructure based autonomous driving.

Miscellaneous

I was born in the beautiful, German-style coastal city of Qingdao, or Tsingtao. I like VR games and photography, espacially aerial photography with drones. I am also trying to improve my very much out of practice piano skills…
