Jie An  [安 捷]

Hi! I am an Applied Scientist at Amazon AGI, where I work on image and video generation models as well as omni understanding and generation models. Previously, I was a Research Scientist at Meta Reality Labs, where I worked on 3D generation and world modeling. I received my Ph.D. in Computer Science from University of Rochester, advised by Prof. Jiebo Luo, where I received the ACM SIGMM Outstanding Ph.D. Thesis Award. Earlier, I earned my bachelor's and master's (with honor) degrees in Applied Mathematics from Peking University, advised by Prof. Jinwen Ma.

I was a research intern at Apple (Seattle, 2024–2025), working with Prof. Alexander Schwing. Before that, I interned at Microsoft Cloud & AI (Redmond, 2023–2024, now part of Microsoft AI) and Meta FAIR (New York City, 2022), hosted by Dr. Zhengyuan Yang and Prof. Harry Yang.

My research primarily focuses on visual content generation. I am particularly interested in foundational generative models, text-to-video generation, physics AI/world modeling, and artistic generation/style transfer. My research is driven by a long-term vision: from developing a fundamental understanding of generative models, to building increasingly capable foundation models, and ultimately advancing toward visual artificial general intelligence (VisualAGI).

On Inductive Biases That Enable Generalization of Diffusion Transformers
Jie An, De Wang, Pengsheng Guo, Jiebo Luo, Alexander Schwing
NeurIPS 2025  |  Project Page  |  Code  |  Featured at Apple MLR  |  BibTex

We find that the generalization ability of DiTs is linked to an attention locality bias: despite access to global tokens, DiTs naturally develop locality patterns in certain attention layers.

Latent-Reframe: Enabling Camera Control for Video Diffusion Model without Training
Zhenghong Zhou*, Jie An*, Jiebo Luo
ICCV 2025  |  Project Page  |  BibTex

We incorporate a 3D point cloud model based on MonST3R into a video diffusion model, which enables arbitrary camera trajectory control in video generation, without training.

We introduce a FIFO-style training-free approach that can enable a video diffusion model to generate infinite long videos in sampling stage.

Video Understanding with Large Language Models: A Survey

MIPR 2024  |  BibTex

We ultilize multi-modal expert features to assist the sentiment analysis task.

QuantArt: Quantizing Image Style Transfer Towards High Visual Fidelity
Siyu Huang*, Jie An*, Donglai Wei, Jiebo Luo and Hanspeter Pfister
CVPR 2023  |  Code  |  BibTex

QuantArt allows the style transfer model take the reference from the whole artistic picture dataset, leading to improved visual fidelity.

We propose a GAN-based multi-domain image translation method that can extend to any unseen domain without the need to train the core backbone.

Is Bigger Always Better? An Empirical Study on Efficient Architectures for Style Transfer and Beyond
Jie An, Tao Li, Haozhi Huang, Jinwen Ma and Jiebo Luo
