Introduction

I am a research associate at the Department of Computer Science, University of York. My current research is on model-based safety assurance standard and tools that are applicable to Cyber-Physical Systems. People in our group are working on the next generation of safety validation and verification methology for emerging systems including intelligent robots and autonomous systems.

I was awarded a PhD in 2019 in the Real-Time Systems Group (RTSG) at University of York. I joined RTSG in 2015, supervised by Prof. Alan Burns and Prof. Neil Audsley. My PhD research involves cooperatively design of control system and real-time task scheduling for Cyber-Physical Systems (CPS). Scheduling task models and methods are proposed and implemented to investigate the scheduling impact on control performance. Trade-offs between scheduling and control are made by a dual-period task model and a flexible adaptation process. This method is interdisciplinary with real-time scheduling theory, control theory and machine learning.

I was awarded a MSc (2014) in Control Systems at the University of Sheffield, and a BSc (2011) in Control Engineering in China. During my undergraduate and postgraduate study, I was involved in many autonomous robot projects and competitions. I am a strong believer of general AI and robots.
