Professor Elgene Lim is a medical oncologist and researcher with a focus on breast cancer research and treatment, and the Principal Cancer Theme Lead at the Faculty of Medicine, UNSW Sydney, and the inaugural National Breast Cancer Foundation Endowed Chair.

He completed his doctoral research, medical and oncology training in Melbourne. Findings from his PhD research under the mentorship of Geoffrey Lindeman and Jane Visvader at the Walter and Eliza Hall Institute, had a major impact on the identification of the culprit cells in carriers of the BRCA1 mutant gene, a hereditary breast cancer syndrome.

He subsequently furthered his research and clinical training at the Dana-Farber Cancer Institute and Harvard Medical School under the mentorship of Eric Winer and Myles Brown, both internationally acclaimed leaders in breast cancer research and clinical trials, through fellowships from the Fulbright Foundation, National Health and Medical Research Council of Australia, and Royal Australasian College of Physicians.
