Scientific Advisory Board Chair & Members

Tomas Lindahl, (Chair) MD, FRS, FMedSci, (Fellow of the Royal Society, Fellow of the United Kingdom Academy of Medical Science) is a Swedish-born British scientist, recognized as one of the founders of the DNA repair field. His achievements include being the first to isolate DNA ligase enzymes in mammalian cells and discover the suicidal DNA methyltransferase. In 2015, he was jointly awarded the Nobel Prize in Chemistry with Paul L. Modrich, Ph.D., and Aziz Sancar M.D., Ph.D., for mechanistic studies of DNA repair.

Professor Lindahl is a Fellow of the Royal Society, the Swedish National Academy of Sciences, and EMBO. He was also awarded the Royal Society's Royal Medal in 2007, the INSERM Prix Etranger in 2009, and the Copley Medal in 2010. He was the first director of Cancer Research UK-funded labs at Clare Hall in London when it opened in 1986, and served as its director for over 20 years. Professor Lindahl is currently Emeritus Professor at the Francis Crick Institute in London, as Clare Hall became part of the Institute in 2015. His distinguished career also includes positions at Rockefeller University, Princeton University, Karolinska Institute in Stockholm, and the University of Gothenburg. He is currently the Chairman of the Scientific Advisory Board Committee of IFOM, (Molecular Oncology Institute) in Milan.

Professor Lindahl’s work has profoundly transformed cancer research. Newer treatments, such as PARP inhibitors, now target the weakness in cancer cells based on faults in their DNA repair abilities. These new treatments, as well as promising candidates, such as Onxeo’s AsiDNA™ DNA break repair inhibitor, wouldn’t exist without the fundamental knowledge developed from Professor Lindahl’s research.

Marie Dutreix, Ph.D., is Director of Research at the Centre for National Research in Science (CNRS) and the co-founder of DNA Therapeutics, the company acquired by Onxeo in 2016. She is an expert in DNA repair & genetic instability, cancer biology and radiobiology, and the inventor of the new siDNA strategy (signal interfering DNA) to inhibit DNA repair, the basis for AsiDNA™. Throughout her career at the Research Department of the Institut Curie, Dr. Dutreix has worked on developing innovative approaches to treat tumors that are resistant to conventional cancer treatments. Before joining the Institut Curie in Paris, she spent three years in the Department of Human Genetics at Yale University with Professor Charles Radding, working on genetics and biochemistry of DNA recombination.

Dr. Dutreix has published over 96 articles in international peer-reviewed journals and has been awarded a number of highly distinguished prizes in science and entrepreneurship. She is a member of several scientific boards (Oxford University, Aviesan Therapeutic Innovation and European Synchrotron Research Facility) and the President of the French Cancer Society. Based on her outstanding accomplishments, Dr. Dutreix was awarded the National Order of Merit in 2013, and is a Knight of the National Legion of Honor since 2017.

Penny Jeggo, Ph.D., is a Professorial Fellow at the Genome Damage and Stability Centre (GDSC) of the School of Life Sciences at the University of Sussex in Brighton, England. Dr. Jeggo has spent a significant number of years studying the response to DNA double strand breaks (DSBs), including pathways of DSB repair, the signaling response to DSBs and, more recently, the interplay between the repair pathways and the signaling response. She has identified two components of the DNA-dependent protein kinase (DNA-PK) enzyme as being important in DNA non-homologous end joining (NHEJ), a pathway by which mammalian cells repair themselves. This discovery was a major breakthrough in understanding the double strand break repair pathway in mammals.

Dr. Jeggo is also an Editor for the scientific journal, DNA Repair, as well as for the International Journal of Radiation Biology, and Nucleic Acids Research. She was Chair and today a committee member of the UK Association for Radiation Research as well as secretary-treasurer of the International association of radiation research. Dr. Jeggo was a member of a number of organizations, including the Cancer Research UK scientific funding committee.
