Junfeng Long「龙俊峰」
Hello there! I am Junfeng Long, a researcher focusing on Control, Reinforcement Learning and Robotics. I am currently visiting Hybrid Robotics at UC Berkeley advised by Prof. Koushil Sreenath. Previously, I was a research intern
at Shanghai Artificial Intelligence Innovation Center(a.k.a. Shanghai AI Laboratory),
where I was working on Reinforcement Learning and Robotics Control advised by Dr. Jiangmiao Pang.
I received my Bachelor's degree in Computer Science and Technology from ShanghaiTech University.
During my undergraduate, I worked with Prof. Youlong Wu
as an undergraduate research assistant on Information Theory and its Application in Distributed Systems.
My research interest mainly falls on Reinforcement Learning, Optimization, Control and Robotics. I am particularly
interested in the intersection of machine learning and control theory and apply them to real robotic systems to achieve
agile and robust robotic locomotion, manipulation and interaction. My goal is to bring together the strengths of machine
learning (generalisability and inference friendliness) and control theory (robustness, theoretical guarantees) to
push forward the frontier of robotic systems. Besides, I am also interested in the theory of optimization and learning.
I am always open to new ideas and collaborations. If you are interested in my research or have any questions, please drop me
an email.

GRUtopia: Dream General Robots in a City at Scale
Hanqing Wang*, Jiahe Chen*, Wensi Huang*, Qingwei Ben*, Tai Wang*, Boyu Mi*, Tao Huang, Siheng Zhao, Yilun Chen, Sizhe Yang, Peizhou Cao, Wenye Yu, Zichao Ye, Jialun Li, Junfeng Long, Zirui Wang, Huiling Wang, Ying Zhao, Zhongying Tu, Yu Qiao, Dahua Lin, Jiangmiao Pang†
Under Review
[Project Page]
[Paper]
[Code]
[BibTeX]
We proposed GRUtopia, the first simulated interactive 3D society designed for various robots. It features (a)GRScenes,
a dataset with 100k interactive and finely annotated scenes. (b) GRResidents, a LLM driven NPC system. (c) GRBench, a
benchmark posing moderately challenging tasks.

On the Optimality of Data Exchange for Master-Aided Edge Computing Systems
Haoning Chen, Junfeng Long, Shuai Ma, Mingjian Tang, Youlong Wu, [α-β ordering]
IEEE Transactions on Communications
[Paper]
[BibTeX]
We propose a coded scheme to reduce the communication latency by exploiting computation and communication
capabilities of all nodes and creating coded multicast opportunities.More importantly, we prove that the
proposed scheme is always optimal, i.e., achieving the minimum communication latency, for arbitrary computing
and storage abilities at the master.
