About OccIDEAS

The OccIDEAS Team

Lin Fritschi MBBS, PhD, FAFPHM

Lin Fritschi is an experienced cancer epidemiologist who is recognized internationally for her expertise in occupational causes of cancer. She has a medical degree and a PhD in epidemiology and is an accredited public health physician. She has led or been involved in case-control studies of cancers of the prostate, colon and rectum, breast and pancreas, as well as non-Hodgkin lymphoma, and childhood leukaemia and brain cancer. In all these studies, assessment of occupational exposure was important and from this vast experience Lin conceived and continued to develop OccIDEAS. She has used OccIDEAS in a novel approach to solving the problem of how to estimate the prevalence of exposure to disease-causing agents at work on a national level.
