Dr. Samantha Terry

Reader/Associate Professor in Radiobiology.

School of Medical Engineering and Imaging Sciences

King’s College London, London UK

Dr. Samantha Terry, a biologist, obtained her PhD in Radiation Biology with a focus on the mechanisms of radiation-induced chromosomal damage at the University of St Andrews, UK, in 2010. Her postdoc at the University of Oxford investigated the influence of the density of chromatin packing on the therapeutic efficacy of molecular radiotherapies. Samantha then moved to an industry-funded postdoc on radionuclide imaging of the tumor microenvironment and monitoring therapy response in tumor and arthritis models at the Radboud UMC, Nijmegen, the Netherlands, in 2011. 


Since 2015, Samantha Terry has started her own research group at King’s College London, UK, to determine how radionuclides used for therapy or imaging affect the cells they are targeting in order to predict how radionuclides and radiopharmaceuticals can be more efficacious. Questions to answer for a whole range of radionuclides are:

  • How can therapeutic radionuclides be used to maximize tumor cell kill for the same amount of radioactivity whilst minimizing damage to healthy tissues?

  • How important is subcellular localization?

  • Does the cell cycle affect response?

  • How can radionuclides be made more effective, in terms of combination therapies?

  • How safe are imaging radionuclides?

  • How do radionuclides and external beam differ in their biological effects?


Samantha Terry has received many grants from industry partners, several early career grants and is principal investigator on various research grants. She is also active on twitter (@syaterry) and acts on organizing committees for molecular radiotherapy meetings, as editorial board member for Nuclear Medicine and Biology, as well as member of the Inflammation and Infection Committee at the European Association of Nuclear Medicine.
