Zhixian Xie

I am PhD student at Intelligent Robotics and Interactive Systems (IRIS) Lab at Arizona State University.

In 2022, I received my B.Eng degree in automation at Shanghai Jiao Tong University, Shanghai, China. I joined IRIS lab for PhD study in 2024.1, working with Dr. Wanxin Jin.

My Research

My research focuses on:

• Dexterous Manipulation integrating model-free learning with physics-based simulation, optimization, and control for solving contact-rich dexterous manipulation efficiently and reliably.

• Robot Learning from Human design structured learning methods to enable robots learn skills from human interactions, with safety, robustness, and data efficiency.

I am actively looking for summer/fall 2026 internship opportunities in robotics and AI.
