About
About
I am a Research Lead at Luma AI, where I focus on building multimodal intelligence. Previously, I was a Research Scientist at Google DeepMind (2024–2026) working on generative AI.
From 2021 to 2023, I worked at Waymo Research Team, an R&D department lead by Dragomir Anguelov. At Waymo, I focused on developing cutting edge technologies for camera-based scene understanding, city-scale reconstruction, and sensor simulation, using deep generative models and neural fields. During this period, most work I co-led/contributed to have been given back to the open-sourcing community through dataset releases (Block-NeRF and neural assets) and open challenge (4D camera segmentation). Prior to this, I worked at R&D Team between 2019 and 2021, Uber Advanced Technologies Group (or Uber ATG Toronto), in close collaboration with Raquel Urtasun. At Uber, my main research area involves simulation, 3D reconstruction, and behavior prediction in the self-driving domain.
I received my PhD degree from the University of Michigan in 2019. At UofM, I focused on cutting-edge research topics lie in the intersection of deep generative models and representation learning with structured and multimodal data, under the supervision of Honglak Lee. Prior to graduate school, I received my Bachelor's degree from ACM Honored Class (交大ACM班), Shanghai Jiao Tong University in 2014. I was a visiting undergraduate student at Rapid-Rich Object Search (ROSE) Lab, Nanyang Technological University (Singapore) in 2014, advised by Junsong Yuan. I also spent time working as an undergraduate research student at MOE-MSR Joint Key Lab of Intelligence Computing (BCMI Lab), advised by Liqing Zhang.
I have also spent my time interning at Adobe Research (San Jose, 2017) and Google Brain & X (Mountain View, 2016, 2017, 2018, & 2019). I feel very honored to receive Adobe Research Fellowship and Google PhD Fellowship which support my PhD research.

General Research Interests
General Research Interests
My primary research interests lie in the intersection of deep representation learning and generative modeling with structured and multimodal data. More specifically, my research has been focused on three related topics: (1) controllable visual content generation and manipulation, (2) self-supervised learning of object shape and motion, and (3) scalable and robust perception simulation for robotic applications. Besides, I have a broad range of interests in developing deep generative models for vision, graphic, and robotic applications.
For a high-level summary of my research agenda, please see the following talk slides:
* PhD dissertation talk: "Learning Deep Controllable and Structured Representations for Image Synthesis, Structure Prediction, and Beyond", June 2019.
* Invited talk at KAIST School of Computing Colloquium: "Learning Deep Controllable and Structured Representations for Visual Content Synthesis and Manipulation", March 2021.
* "Learning Deep Controllable and Structure Representations for Autonomous Driving Simulation", more recent work.
