Manuel Bardiès obtained his Doctorate on radiopharmaceutical dosimetry from Toulouse University, France in 1991. He has been developing his research in radiopharmaceutical dosimetry within INSERM (National Institute of Health and Medical Research) since 1992 in Nantes, then in Toulouse (2011), and currently in Montpellier (2021-).
Professor Bardiès was one of the founders of the EANM Dosimetry Committee (member from 2001 to 2013, chair 2009 to 2011). He chaired EFOMP Science Committee between 2014 and 2016 and is currently chairing the newly established EFOMP Special Interest Group for radionuclide internal dosimetry.
He has been involved in education in various European structures (ESMIT, ESMPE). He is a member of the Board of the medical physics resident program in France and was appointed Professor by the French National Institute for Nuclear Science and Technology (INSTN) in June 2018.
The group led by Professor Bardiès is primarily involved in radiopharmaceutical dosimetry, at various scales (cell, tissue, organ). This requires the ability to assess radiopharmaceutical pharmacokinetics in vivo, through quantitative SPECT or PET small-animal imaging, or in the clinics. An important part of the research activity involves Monte Carlo modelling of radiation transport. The objective is to improve molecular radiotherapy by allowing patient-specific treatments (personalised medicine).
