Professor Rajan further honed his skills during a clinical and research fellowship in robotic “keyhole” prostate cancer surgery at the Karolinska Institutet and University Hospital in Stockholm, Sweden. Upon returning to Glasgow in 2015, he was appointed as a Consultant Urologist specialising in laparoscopic “keyhole” kidney cancer surgery. Later that year, he joined St. Bartholomew’s Hospital (Barts Health NHS Trust) and University College London NHS Foundation Trust, where he currently specialises in robotic prostate cancer and complex advanced testicular cancer surgeries.

In addition to his clinical practice, Professor Rajan is a Professor of Urology and Robotic Surgery at Barts Cancer Institute, Queen Mary University of London. He leads an internationally renowned laboratory-based research group and conducts clinical trials to develop new treatments for prostate and testicular cancers. His research has attracted nearly £2.5 million in funding, and he has published over 80 articles, book chapters, and reviews.

Professor Rajan holds fellowships with the Royal College of Surgeons of England, the Higher Education Academy, and the Alan Turing Institute. He is a member of the National Cancer Research Institute’s Advanced Prostate Cancer and Germ Cell Tumours Research Groups. Additionally, he serves as an Associate Professor of Urology at University College London and is a member of the UCL Urology Clinical Academic Board.

Outside of his professional commitments, Professor Rajan enjoys cycling and running. He also seeks the challenge of visiting exotic, off-the-beaten-track locations, particularly where he can practise his language skills in Tamil, and to a lesser extent, Hindi and Spanish.
