Professor Allen’s contribution to medical research over the past 20 years has covered the full spectrum of laboratory, clinical and population health. Her PhD culminated in Australia’s first liver cell transplantation, her postdoctoral work resulted in first author publications in New England Journal of Medicine and The Lancet and her seminal work in food allergy is the first to describe the emerging epidemic as well as identify and rigorously test the first modifiable factors for implementing prevention of this new phenomenon.
