Dr Peng Guo

PhD Canterbury in Bioengineering

Profile Image
Research Fellow


Peng finished his PhD at the University of Canterbury, focused on quantifying nurse workload in ICU by developing a novel tracking system, and study the correlation between nurse workload and patient acuity level, to optimized allocate nurse resource to the right patient. Thesis Title: Analysing Nursing Workload in Intensive Care Unit by Using a Novel Objective Tracking System. Previously he worked as a mechatronic engineer in product design field for 2 years in China.

Now he is working in Auckland Bioengineering Institute (Auckland University) as a Research Fellow, focusing on developing a novel eye tracking system to precisely identify optokinetic nystagmus (involuntary eye movement) for adults and children, to identify eye disease and cure them. 

He will keep on working in bio-engineering field, using research and engineering skills to develop novel practical product that can help patients and ease their pain.

Research | Current

His work focus on developing a novel eye tracking system to accurately detect optokinetic nystagmus (OKN) for adults and children, to help test visual acuity and identify eye disease. In addition, he focuses on develop tracking systems into a readily portable mobile device (Tablet and smart phone), that will help improve public health.



·         Lead the development and validation of eye tracking system (algorithms and hardware) for identifying and processing of eye movement (the optokinetic reflex).

Teaching / Supervision

·         Supervise the research activities of graduate students (BME, ME & PhD students)
