Professional background

I am a consultant in pain medicine and anaesthesia at the National Hospital for Neurology and Neurosurgery and UCLH.

I completed my training in anaesthesia rotating between the King’s College London, University College London, Chase Farm and Barnet and the Royal Free Hospitals. My Advanced Pain Medicine fellowship was based at the Imperial School, London and I held appointments at Chelsea and Westminster, Hillingdon and The Royal Marsden Hospitals. I went further supplementing my sub-specialty pain training with attachments to Guys’ and St Thomas’ hospitals (advanced neuromodulation) and Cleveland Clinic, OH, USA (interventional management of headaches) before taking up my current permanent post as a consultant.

My clinical activities are centered around the multidisciplinary management of acute, chronic and cancer pain.

I have the following clinical interests:

  • interventional cancer pain management
  • urogenital / pelvic / abdominal chronic pain
  • rare inherited pain conditions such as erythromelalgia, CIPA and Paroxysmal extreme pain disorder
  • central pain syndromes
  • neuropathic pain
  • intraoperative anaesthetic management of complex patients with the aim of preventing development of persistent postoperative pain (PPP)
  • pain originating in the back, spine and neck
  • other chronic musculoskeletal (MSK) pain disorders

Research interests

I obtained my Ph.D. in Neurosciences (Pain) in 2012 from Wolfson Institute for Biomedical Research, University College London.

My research currently centres on mechanisms of neuronal hyperexcitability in patients affected by complex chronic pain disorders.

My research interests are:

  • pain channelopathies
  • painful peripheral neuropathies
  • genetics of chronic pain
  • personalised analgesia
  • ketamine as an analgesic drug

Evolving areas: use of DNA in treatment of chronic pain
