A national organisation focused on neuro-oncology
Our collective interest in treating, caring and researching brain tumours brought us together to start a national organisation that is focused on neuro-oncology. Initially starting as a special interest group, we quickly developed into an incorporated national Society comprising of over 80 members. Coming from regions all over Aotearoa, our members include clinicians, researchers and patient support community groups. We are an integrated member of the Asian Society of Neuro-Oncology, providing us with access to international collaborations and resources. The NANOS hopes to become an organisation which fosters collaborations, facilitates community communications, and brings hope for brain tumour patients in Aotearoa.

Thirayan Muthu
Committee member
I completed my postgraduate M.Ch.Neurosurgical training from the Madras Medical College, University of Madras in 1992 and then went on to the Republic of Ireland and the United Kingdom, where I further completed my FRCS (Edin) in Neurosurgery in 2004. I was then offered the opportunity to start the Department of Neurosurgery at the Waikato Hospital in 2006, by late Dr Balakrishnan. I obtained my FRACS in Neurosurgery in 2015. Over the last 20 years the department has grown and we are now a RACS credentialled Neurosurgical training unit. My special interests are management of trigeminal neuralgia, degenerative conditions of the cervical and lumbar spine and neurovascular and neuro-oncological conditions involving the brain and spine. I am currently the Clinical Surgical Supervisor for Neurosurgery.

Rebecca Lissiman
Committee member
Rebecca Lissiman is a Wellington-based Neurosurgical Clinical Nurse Specialist with a specific passion for neuro-oncology. Following her neurosurgical training in the UK, she moved to New Zealand in 2012, where she supports patients and whānau from diagnosis. Acting as a vital anchor, she brings clinical safety and continuity to complex health journeys, working closely with Brain Tumour Support NZ and the Cancer Society to champion equitable, patient-centred care.
