Dr Khalifa qualified with a distinction from the University College of London Medical School in 2006. Following his surgical training, he undertook clinical and interventional radiology training at London Northwest Hospital and Imperial College London. This was followed by dedicated interventional hepatobiliary, oncology and vascular radiology fellowships.

As well as general diagnostic radiology, Dr Khalifa is experienced and has expertise in both vascular and non-vascular intervention. He has developed interests in hepatobiliary intervention, management of complex vascular malformations, complex below knee revascularisation, fibroid embolization, tumour embolization & tumour ablation. He has specialist expertise in performing procedures via the transradial approach, using the small vessels in the wrist, which is less invasive and speeds patient recovery.

Dr Khalifa is currently pioneering the prostate artery embolization service at the Royal Free Hospital – a minimally invasive technique used for treating enlarged and troublesome prostates.
