Sir John Walsh Research Institute researcher profile

Dr Joanne Choi

PositionLecturer
DepartmentDepartment of Oral Rehabilitation
QualificationsBDentTech (Hon) PhD
Research summaryDental materials, craniofacial biology and clinical oral physiology

Research

I conduct experimental and observational research in dental materials, craniofacial biology and clinical oral physiology. I carry out qualitative and quantitative analysis of the mechanical properties and failure mechanisms of restorative dental systems. I also carry out observational research in the oral environment using portable measurement systems.

For my PhD, I developed and validated a wired sensor system to monitor intraoral pH and temperature for long-term periods, the results of which can be used in identifying and evaluating causal factors involved with dental wear.

I am part of the Biomechanics and Oral Implantology and Craniofacial Biology Programmes of the Sir John Walsh Research Institute.
