Derek Williamson is a science educator with 25 years’ experience in varied settings. Originally a zoologist, he realised it was far more enjoyable talking about other people chasing frogs around swamps than chasing them himself. As the director of the Museum of Human Disease, a teaching collection of the faculty of Medicine at UNSW, he is daily faced with the need to engage students not just with science but with disease – a double-edged sword. He is currently undertaking a Masters by research on ways to promote museum visitors’ learning experience.
