**About the Editors**

**Derek F. H. Pheby** is recently retired. His most recent appointment was as Visiting Professor of Epidemiology at Buckinghamshire New University, UK. He was formerly a cancer epidemiologist, and was the UK permanent representative on the Steering Committee of the European Network of Cancer Registries and chairman of its Data Definitions Group. He was the founder and first chairman of the UK Association of Cancer Registries. More recently, he developed an interest in ME/CFS following the serious illness of a close family member. He was responsible for establishing the EUROMENE (European ME/CFS Network) research collaboration, and chaired its Socioeconomics Working Group. He was a trustee of the UK organisation Action for ME, and is a patron of the ME Association. He was awarded a Haldane Prize by the Royal Institute of Public Administration in 1983, and the Silver Medal of the European Society for Person-Centred Healthcare in 2018.

**Kenneth J. Friedman**, Ph.D. is an adjunct Associate Professor of Medicine at the School of Osteopathic Medicine, Rowan University, Stratford, NJ, USA. A neurophysiologist and pharmacologist by training, he taught medical, dental and graduate students at the New Jersey Medical School for 34 years while pursuing basic research in the area of membrane physiology. When medical science failed to diagnose, treat or cure his daughter's Chronic Fatigue Syndrome in the mid-1990s he began his research and pursuit of the science that underlies ME/CFS and similar chronic illnesses. Currently, he produces and disseminates educational materials for healthcare providers which assist them in providing care for patients suffering from Post Active Phase Infectious Syndromes (PAPIS).

**Modra Murovska**, MD, PhD, Associate Professor, Lead Researcher, Director of the Institute of Microbiology and Virology, R¯ıga Stradin¸ s University, Full Member of the Latvian Academy of ˇ Sciences. Her general interest is virology.

The ongoing projects under her guidance are "Reducing networking gaps between R¯ıga Stradin¸ sˇ University (RSU) and internationally - leading counterparts in viral infection-induced autoimmunity research (VirA)" (H2020-WIDESPREAD-2018-2020); "Selection of biomarkers in ME/CFS for patient stratification and treatment surveillance/optimisation" (Project of the Latvian Council of Science). Her scientific interests are blood-borne viruses, persistent viral infections and their association with human pathologies, the implication of viral infections in the pathogenesis of chronic inflammatory and autoimmune diseases (including neural diseases), and the role of viral infections in cancer development. In 2000, M. Murovska received the American Society for Microbiology Morrison Rogosa Award.

**Pawel Zalewski** completed his postdoctoral training at Nicolaus Copernicus University in Torun (2011-2015), where his research work and interests focus on physiotherapy and the related areas of physical medicine, and applied and clinical physiology. He currently works in the Department of Exercise Physiology and Functional Anatomy, Faculty of Health Sciences, Nicolaus Copernicus University. His scientific achievements largely concern the influence of environmental and disease factors on physiological adaptation of the autonomic nervous system, as well as on biological mechanisms underlying the development of dysautonomia and related chronic fatigue. A major recent focus of research by his research group is on pathological mechanisms, biomarkers, diagnosis

and therapy of chronic fatigue syndrome (ME/CFS), which is being undertaken in collaboration with international colleagues at the Universities of Newcastle and Oxford in the UK, Griffith University in Australia, and many others. He also actively promotes public understanding of science in these areas of interest, and in the effectiveness of the therapeutic influence of physical training in various clinical conditions.
