Debbie Watson is a PhD candidate at the University of Technology Sydney investigating adaptive urban navigation for older adults. Her research explores how physiological stress signals captured through wearable devices can inform real-time routing systems that support safe, confident movement through urban environments. Drawing on gerontechnology, spatial cognition research, and human-computer interaction, her work aims to reduce the environmental and cognitive barriers that contribute to social isolation in ageing populations. Debbie also holds a senior leadership role in the technology sector, with deep expertise in software architecture and solution design.
