Mr Joseph Hewitt
School of Medicine
College of Health
I'm currently an accredited general surgical registrar in the Eastern NSW training network. My Master of Philosophy (Surgery) thesis examines risk assessment in emergency laparotomy. This consists of a systematic review, an interview based study of general surgeons and trainees and an audit of risk assessment in South Australian hospital. I'm also a Clinical Lecturer with the University and am engaged regularly with teaching medical students.
