About

The short history of my life is: I was born in Singapore, then moved to Vancouver, BC, Canada at the age of 11, then I moved to the US for grad school (Pittsburgh, PA) and work (San Francisco bay area, CA). My parents are both Shanghainese; they moved from Shanghai to the US for grad school, then to Singapore for work, and now they reside in Canada.

1 Work

I work in what’s called Spatial AI nowadays. Basically, I have a decade of experience in making sense of the 3D world via simultaneous localization and mapping (SLAM) with lidar, cameras, and other sensors, and more recently, stuff like Gaussian splatting. I currently work at NVIDIA on their self driving car project, on context fusion.

2 Education

At CMU, my advisor was George Kantor. I worked on SLAM using a combination of cameras and a lidar, for an autonomous off-road vehicle.

My thesis is called Vision-Enhanced Lidar Odometry and Mapping. It is about combining several different SLAM algorithms, each with different strengths and weaknesses, so that a robot can function robustly in many different environments.
