I'm a PhD student at the University of Pennsylvania, where my research focuses on robot learning and computer vision. I'm advised by Prof. Eric Eaton, and closely working with Prof. Dinesh Jayaraman and Prof. Lingjie Liu.

I have worked as a Software Engineer at Google (2022), as an Intern at Robotics Institute, CMU (2021), and as an Intern at Instagram (2020).

Please feel free to reach out if you're interested in research discussion / collaboration! I'm also always looking to mentor highly motivated students to work on research projects. Please send me an email if you are interested.

Research

I am interested in scalable robot learning. Below are my works.

Pixie: Physics from Pixels

Long Le, Ryan Lucas, Chen Wang, Chuhao Chen, Dinesh Jayaraman, Eric Eaton, Lingjie Liu

Preprint, 2025

( website, code (coming soon!) )

We predict 3D physics from distilled CLIP features, enabling generalization and fast inference across scenes. Pixie produces physics that are 2.2–4.6× more realistic while running 10³× faster.

Articulate Anything

International Conference on Learning Representations (ICLR), 2025

( website, twitter, paper, code )

A major bottleneck in scaling robot learning in simulation is the lack of interactable 3D environments. We present a SOTA method, leveraging VLMs to automatically generate articulated 3D models from any input modality including text, real-world images, or videos.

DCL

Distributed Continual Learning

Long Le, Marcel Hussing, and Eric Eaton

Preprint, 2024

(paper)

We study the intersection of continual and federated learning, in which independent agents face unique tasks. We develop the mathematical formulation for the setting, develop algorithms for sharing data, model weights, and modules, and provide extensive empirical results across network bandwidths, and topology.

Nature Survey

A collective AI via lifelong learning and sharing at the edge

A Soltoggio et al

Nature Machine Intelligence, 2024

(paper)

We survey approaches and challenges in developing a collaborative life-long AI system on edge devices.
