Inventing solutions to everyday problems

Geoff develops technologies for two broad purposes:
  • To prevent injury and disease
  • To help individuals and their family caregivers continue to live in their own homes as they age
He has maintained a focus on the reduction of falls through the development of innovative mobility products, non-slip winter footwear and improvements to accessibility and building codes. He has made significant advances in preventing hospital acquired infections by improving hand hygiene. His recent involvement in the development of a disposable instrument for home diagnosis of sleep apnea has the potential to significantly reduce the prevalence of cardiovascular complications resulting from untreated sleep apnea. Geoff has been responsible for many products that assist people's independence, including innovative wheelchairs and bathroom aids. Many of his inventions have reduced the physical burden of caring for people, including the prevention of back and shoulder injuries in professional nurses and family caregivers caused by lifting and moving people.
