Research Associate (Postdoc) · Robotics & Manipulation · Cardiff University
I develop robotic systems that manipulate rigid, deformable, and granular objects using learning-based and physics-based methods. My research combines differentiable simulation, system identification, reinforcement learning, and affordance modelling to build capable and trustworthy robots for real-world settings.

About
I am a research associate in the School of Engineering at Cardiff University. My current work spans robotic manipulation of deformable and granular materials, differentiable physics-based modelling, and automation for robotic laboratory systems.
I completed my PhD at Cardiff University in October 2023, where I studied hierarchical reinforcement learning and affordance learning for robotic manipulation. Before that, I received my Bachelor’s and Master’s degrees in Mechanical and Industrial Engineering from Guangdong University of Technology, China.
I am also committed to open-source research software and reproducible robotics.
