Dr Livieratos is a Clinical Scientist (Medical Physicist) in Nuclear Medicine at Guy’s & St Thomas’ Hospitals and adjunct Reader in Medical Physics at King's College London. He received an NIHR Senior Clinical Lecturership award in Imaging Sciences (radionuclide theranistics). He previously worked in PET methodology at Hammersmith Hospital, Imperial College alongside the MRC PET Oncology and PET Cardiology research groups on radiotracer image quantification and novel schemes for patient respiratory motion correction. He subsequently worked as clinical scientist at Guy’s & St Thomas’ in diagnostic and therapeutic applications of radionuclides. This included the commissioning and clinical implementation of the first SPECT/CT in Europe with diagnostic CT. He is actively involved in undergraduate and postgraduate teaching of medical physics at King’s College and the supervision of post-graduate students and trainee clinical scientists. He served as program director for the MSc Clinical Science - Medical Physics at King's College commissioned by Health Education England. His research interests include radio-theranostics, multi-modality imaging, image quantification and analysis for translational applications and patient-specific dosimetry in molecular radiotherapy.

Dr Livieratos is a course teacher/leader on the following courses: 7MIGEP10 Nuclear Medicine Physics, 7MIGEP28 Further Nuclear Medicine Physics, 7MUGEP12 MSc Research Project (Nuclear Medicine).
