After studying Medicine in Manchester, Mr Gnanalingham completed his Neurosurgical training in London. This included specialist training in Complex spinal surgery and Pituitary at the National Hospital for Neurology and Neurosurgery. He learned minimally invasive techniques at several centres in the UK and US.

He was appointed as a Consultant at the Greater Manchester Neuroscience Centre at Salford Royal Foundation Trust (SRFT) in 2005. He is also an honorary senior lecturer at the University of Manchester.

His sub-speciality interests include pituitary, neurooncology and complex spine surgery, utilising minimally invasive techniques. He is the lead consultant for Pituitary surgery in Manchester and introduced the endoscopic approach to the region. With respect to the spine, Mr Gnanalingham has particular interests in degenerative spinal disease, spinal trauma, tumours, spinal arthroplasty and other motion preserving technologies. He has a preference for minimally invasive spinal approaches that minimise post-operative pain and speed up post-operative recovery.

In recognition of his expertise, Mr Gnanalingham is frequently invited to speak at national and international meetings and conduct workshops for spinal and pituitary disorders. SRFT is a national and international Visitation centre for Minimally Invasive Surgery, with regular visits from surgeons wishing to learn such ‘key hole’ surgical techniques. He offers an international fellowship in minimally invasive surgery. He has a strong interest in clinical and basic science research in Neuroscience, qualified to a doctorate level, with over 80 publications and international presentations.
