Dr Marie-Claude Gregoire

Research Theme Leader


Dr Marie-Claude Gregoire is the leader of the Human Health research theme in NSTLI.

She has moved to Australia in 2005 to establish and lead the in vivo molecular imaging platform at ANSTO.

She established and led the LifeSciences division in ANSTO between 2011 and 2016.

Marie-Claude worked in industry for 2 years, and at Mass General Hospital, Boston, for another two years, before being recruited at the Centre National de la Recherche Scientifique (CNRS). She spent 12 years working as a platform and research leader in the field of molecular imaging with nuclear techniques in partnership with the Commissariat des Energies Alternatives (CEA), France.

Her main research interests are in functional exploration of biological pathways with complementary nuclear techniques and multi-modality imaging such as in vivo PET, SPECT, CT, MRI and post mortem imaging. Marie-Claude has produced over 100 journal publications and conference.
