Research interests

Geometric uncertainties in radiotherapy, image processing and registration, TCP and NTCP modelling, second malignancy risk estimation, maximum likelihood estimation, organ motion management, dose calculation, radiomics, data mining, adaptive radiotherapy, proton therapy and stereotactic treatments.


Jothy Selvaraj worked as a medical physicist at the All India Institute of Medical Sciences, NewDelhi, India. He later moved to the UK to obtain his PhD from the University of Liverpool, UK workingat the Clatterbridge Cancer Centre. His doctoral thesis investigated the impact of geometric uncertainties, organ motion and clonogen distribution on tumour control probability (TCP). Helater spent a brief stint at the NKI-AvL, Amsterdam as a postdoctoral scientist working on TCP andnormal tissue complication probability (NTCP) modelling of stereotactic lung treatments. He nowworks 0.5 FTE as a senior medical physics specialist implementing new treatment techniques and developing in-house solutions for QA procedures besides working 0.5 FTE as a lead medicalphysicist, R&D in the Medical Physics and Radiation Engineering department, Canberra Hospital,Australian Capital Territory. He is also an HCPC registered clinical scientist. His research interestsinclude the effect of geometric uncertainties in radiotherapy, radiobiological/mathematical modellingand image processing applied to radiotherapy. He is also a passionate computer programmer
