03 / Background
Mathematics at the foundation.
Engineering in practice.
I trained in mathematics and applied mathematics at the University of Dhaka before completing a PhD in Mechanical Engineering at James Cook University in 2009.
My academic career has included research appointments at James Cook University and Queensland University of Technology. I joined UTS as a Senior Lecturer in December 2017.
Alongside fundamental research, my work includes industry-supported projects in first aid and CPR device calibration, fan blade design and aerospace engineering.
