Arthur Mallinson

Arthur Mallinson was born in Toronto, Canada on April 20, 1952. He hoIds a B.Sc. in Biological Sciences and an M.Sc. in neurophysiology, both from Simon Fraser University in Burnaby, Canada.

For the last 30 years he has been worked as a neurophysiologist in the Neuro-otology unit at Vancouver General Hospital, a diagnostic unit in a tertiary care teaching hospital. He performs clinical vestibular assessments and also serves as a consultant to other centres across Western Canada in interpreting difficult or unusual vestibular assessment results. He is a clinical instructor in the Faculty of Medicine at the University of British Columbia, and teaches vestibular physiology and clinical assessment to otolaryngology residents, medical students, audiology students, visiting clinicians and other paramedical professionals.

In the past Art has also been active in developing and teaching into the Electrophysiology program at the British Columbia Institute of Technology, which is the only English language program in Canada of its kind. He has also served as a Lecturer and Laboratory Demonstrator/Assistant, teaching Neuroanatomy/ Neurophysiology in the School of Rehabilitation Medicine, at the University of British Columbia.

He was involved in the initiation of the intra-operative monitoring program at Vancouver General Hospital, and also helped develop the ototoxicity monitoring program at the hospital.

Art has been performing and personally interpreting Computerized Dynamic Posturography assessments for 22 years, including hundreds of medical legal posturography assessments. He is the co-author of a booklet about medical legal evaluation of balance and also the co-author of a learning module on vertigo for the British Medical Journal.

Art has been actively involved in ongoing research for the last 30 years with his colleague Dr. Neil Longridge. He is a member of the Barany Society, the premier world society on dizziness and balance. He is also a member of the International Society for Posture and Gait Research (formerly called the International Society of Posturography). He serves on the editorial review board for five journals (Journal of Vestibular Research, Gait and Posture, Otology and Neurotology, Experimental Brain Research, Clinical Neurophysiology). He has been an invited speaker at a number of conferences, and has designed and given many seminars on vestibular assessment and evaluation to medical and paramedical professionals.

ACKNOWLEDGEMENTS

I am first of all extremely grateful to Maastricht University for allowing me to pursue this degree, and I would like to convey my sincere thanks to the members of the faculty and especially members of my committee who have supported me through this journey. A special word of thanks must go to prof. dr. Kremer who was my initial contact at Maastricht University and whose efforts enabled me to begin my journey. I am indebted as well to prof. dr. Stokroos for chairing my examining committee and spending the time to read my work.

It has been an honour and a privilege to be researching in the same field as the distinguished scientists gathered at Maastricht University to take part in my thesis defence. I value them as inquisitive researchers and colleagues but also value them as friends. They make the pursuit of knowledge much more enjoyable and extremely satisfying.

Several specific people need to be singled out for their encouragement. Prof. dr. Philippe Perrin has always been eager to share his knowledge and insight with me and to look at a research challenge in a different way. Prof. dr. Mans Magnusson has been an inspiration and an encouragement for many years, and has convinced me that scientists who think differently are not necessarily wrong and may in fact be increasing their contribution to science because they think differently. He has also emphasized to me that research must be enjoyable and if this is not the case, it is one's duty to make it enjoyable.

Despite our geographical separation, my promotor, prof. dr. Herman Kingma, has always shown by example how important it is to be passionate in pursuing one's interests. As my friend and research colleague over the years, he has been insightful and inquisitive, and as my promotor he has continually encouraged me, guided me and emphasized the importance of always trying to formulate new questions, and pursue answers to them, especially in a field where so little is understood. For his efforts on my behalf to help me complete this journey, he has my deepest gratitude.

Research endeavours always start with interests kindled and nurtured by others, and there are several people who have served this purpose in my research. A debt of gratitude goes out to prof. dr. Adolfo Bronstein whom I first met over 20 years ago, and who has always inspired me and served as a colleague, collaborator, sounding board and friend. We have shared many good times together and enjoyed fascinating stories and thoughts about research ideas, patients and future endeavours. Thanks also must go to Dr. Lewis Nashner, and Dr. Owen Black, whose work has fascinated me and inspired me for over 25 years.

In order to pursue this research endeavour successfully, while at the same time being a father, a husband and working in a busy diagnostic clinic, I have had the good fortune to have a solid source of encouragement, mentor, teacher and understanding medical director who is also a highly regarded clinician in my colleague, Dr. Neil Longridge. As research partners we have shared ideas and countless enthusiastic hallway conversations prompted by a particularly fascinating clinical case. Many thanks for all your support, Neil.

On a personal note, the joy of research is heightened immeasurably when you are a father to three wonderful, intelligent children who always listen and consistently show an interest in my latest research project. For Christopher, Daniel and Kyle, I am forever thankful.

And finally, to my amazing wife Tish, who has been my partner in all things for over 40 years, this is for you.
