Bill Contoyannis is a qualified mechanical and biomedical engineer and ergonomist with extensive experience in rehabilitation engineering, human biomechanics and ergonomics. He is a skilled incident investigator specialising in risk identification and injury prevention.

He has been involved in a broad range of rehabilitation, assistive technology and more specifically prosthetics and has made a significant contribution to these fields including, incident investigation, education, research, advice and clinical support.

His vast experience has led him to be a highly sought after consultant on matters including the design of products used in both the disability and general sphere. This has included the ergonomic and engineering design and assessment of wheelchairs, artificial limbs (and the components included in these) and patient lifting devices such as overhead support systems and portable patient hoists.

Some examples of his work include:

  • Investigation of medical technology involving failure incidents and injury to patients (Various Australian government departments of health, coroner’s department and private health service)
