Sonya Marshall-Gradisnik

Sonya M. Marshall-Gradisnik, BSc (Hons), PhD, is co-director (alongside Professor Donald Staines) of the National Centre for Neuroimmunology and Emerging Diseases (NCNED) at Griffith University in Australia. Her expertise is in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis with particular focus on Natural Killer Cell function and signalling pathways, T regulatory and B cell phenotypes and cytokine production, and transcriptional profiling and gene expression. In her studies, she compares the changes of the different cells of the immune system in relation to the severity of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis.

International Consensus Criteria
She is one of the authors of the 2011 case definition, International Consensus Criteria.

International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis
Marshall-Gradisnik is on the Board of Directors of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (IACFS/ME).

Biomarker Patent
In 2016, Griffith University filed for a patent for a biological marker (Patent Publication number WO2016023077 A1) for the diagnosis and management of ME and CFS. Sonya Marshall-Gradisnik and Ekua Brenu are listed as the inventors. The application states: "The present invention resides broadly in the use of at least one miRNA as a biological marker for identifying or diagnosing a subject having CFS and/or ME."

Open Letter to The Lancet
Two open letters to the editor of The Lancet urged the editor to commission a fully independent review of the PACE trial, which the journal had published in 2011. In 2016, Dr. Marshall-Gradisnik, along with 41 colleagues in the ME/CFS field, signed the second letter.

Clinic location
National Centre for Neuroimmunology and Emerging Diseases (NCNED) is located at Griffith University on the Gold Coast, Queensland, Australia.
