Sir Martin was the first scientist to identify embryonic stem cells, which can be adapted for a wide variety of medical purposes. His discoveries are now being applied in virtually all areas of biomedicine – from basic research to the development of new therapies. In 2007, he was awarded the Nobel Prize for Medicine, the most prestigious honour in world science, for these “ground-breaking discoveries concerning embryonic stem cells and DNA recombination in mammals.”

Sir Martin has published more than 120 scientific papers. He was elected a Fellow of the Royal Society in 1993 and is a founder Fellow of the Academy of Medical Sciences. He was awarded the Walter Cottman Fellowship and the William Bate Hardy Prizes in 2003 and in 2001 was awarded the Albert Lasker Medal for Basic Medical Research in the US. In 2002 he was awarded an honorary doctorate from Mount Sinai School of Medicine in New York, regarded as one of the world’s foremost centres for medical and scientific training. He has also received honorary doctorate awards from the University of Bath, University of Buckinghamshire, University College London, University of Wales and the University of Athens. Sir Martin gained his BA in Biochemistry from Christ College, University of Cambridge in 1963. He received an MA in 1966 and a DSc in 1966. In 1969 he was awarded a PhD from University College, London. He joined the Cardiff University School of Biosciences in 1999. He was knighted in 2004 for his services to medical science and in 2009 was awarded the Gold Medal of the Royal Society of Medicine in recognition of his valuable contribution to medicine.

Dr Robertson gained his PhD in molecular virology from Macquarie University, Australia before undertaking Post-Doctoral training in gene regulation and nuclear architecture at Oxford. He returned to Australia as a Post-Doc in the laboratory of Prof. Emma Whitelaw at University of Sydney where he set up a transgenic mouse facility and discovered repeat-induced silencing as an epigenetic process on mammalian transgenes. Dr Robertson then moved to Westmead Hospital Millennium Institute where he pursued studies on the fibrotic liver disease NASH and the impact of inducible xenobiotic/drug interactions on drug clearance pathways. A component of this work involved creating a transgenic mouse model for studying gene regulation of human CYP3A4, the main pathway for drug metabolism. The model was subsequently commercially leveraged as a screening tool for drug development. At the ANZAC and Garvan Institutes in Sydney (2004-2014), Dr Robertson explored the impact of cancer-associated inflammation in repressing drug clearance leading to excessive toxicity. Dr Robertson also explored the link between chronic inflammation and disrupted energy metabolism as the basis for cancer cachexia. A key discovery from this work was the activation of thermogenesis in white & brown fat, linked to body wasting. These findings were published in Cancer Research and Cell Metabolism where it was ranked amongst the 10th highest papers in the latter journal. He has published ~60 papers with >3,000 citations.
