Medical Imaging Blogger | Radiochemistry | Oncidium Ambassador

BIOGRAPHY

Dr Sean Kitson is a prominent figure in radiochemistry with extensive academic and professional achievements. He earned his PhD in Organic Chemistry and Molecular Toxicology from the University of Newcastle-upon-Tyne, a postgraduate diploma in medical physics, and an MSc in science from the Open University. His thesis explored carcinogenesis mechanisms linked to urethane.

He currently represents the Oncidium Foundation as an Ambassador in Northern Ireland and works as a Radiochemistry Investigator in the Department of Technology at Almac Sciences. His experience includes a significant stint as a senior radiochemist at GE Healthcare, where he focused on carbon-14 custom labelling and synthesis.

Recognised for his contributions, Dr Kitson has received multiple awards, such as the 2006 Wiley—Journal of Labelled Compounds and Radiopharmaceuticals—Young Scientist Award for his radiosynthesis work on the Parkinson’s drug apomorphine. He was the founding Editor-in-Chief of Current Radiopharmaceuticals.

His research spans new chemistry for functional groups, carbon-14 radiolabelling, and radiotheranostics. With over 50 publications, his work is influential in radiochemistry and radiopharmaceuticals, highlighted by his roles in scientific and editorial committees.

Additionally, Dr Kitson shares his expertise in medical imaging through the “Open MedScience” blog, focusing on the latest PET, SPECT, and radiotheranostics techniques. His insights help demystify complex radiochemical concepts for broader clinical applications.

JLCR YOUNG SCIENTIST AWARD

  • My contribution to radiochemistry was acknowledged by winning the first Wiley JLCR Young Scientist Award in 2006 for the elaborate carbon-14 radiosynthesis of the Parkinson’s drug apomorphine.
