From Israel: Prof. Jeffrey Hausdorff, currently the Director of the Laboratory for the Analysis of Gait and Neurodynamics at Tel-Aviv Sourasky Medical Center (TASMC), Senior Lecturer at the Sackler School of Medicine Tel-Aviv Universiry, and Lecturer in Medicine at Harvard Medical School. With a background in biomechanics and biomedical engineering, Dr. Hausdorff studies neurodynamics and the application of statistical physics to the study of gait, fractal physiology, heart rate dynamics, tremor, and brain function, with a special focus on aging and falls in older adults. In general, the goal of his research is to more completely and precisely quantify normal and pathophysiologic function so that we may better identify, predict, and, ultimately, prevent age- and disease-related changes, as well as "catastrophic" events such as sudden cardiac death, freezing of gait, and falls in the elderly.

From Italy: Dr. Francesco Landi, currently Assistant Professor of Geriatrics at University "Cattolica del Sacro Cuore" in Rome (Italy). As regards clinical duties, he has patients' care responsibility (Geriatric Orthopaedic Unit, and Geriatric Rehabilitation and Occupational Therapy Unit, Acute Care Unit) and he is Geriatric Consultant, Nursing students tutor, Occupational therapists tutor. He participated in more than 230 national and international congresses and he is author of more than 140 papers/ letters in peer reviewed journal. The main field of his research are: epidemiology, frail elderly, geriatric syndromes, pharmacology, rehabilitation, comprehensive geriatric assessment, geriatric services.

From Slovakia: Dr. Peter Takac, currently Associated Professor at University of P. J. Šafárik, Faculty of Medicine, Košice, and the Head of Department of Physical Medicine and Rehabilitation, Pavol Jozef Šafárik University in Košice, Faculty of Medicine. The main fields of his research are: healthy aging and his impact on health care, autonomic nervous regulation in response to changes of posture, spectral analysis of heart rate variability in relation to age, biofeedback in rehabilitation medicine.

From Switzerland: Dr. Reto W Kressig, currently the Head of the Geriatric University Clinic (Acute Geriatrics Division, Memory Clinic, Basel Mobility Center), University Hospital Basel, Switzerland. The fields of his research interests are: gait biomechanics, human performance, exercise, and physical function in relation to principles of geriatric rehabilitation and fall prevention; relation between cognitive impairment and motor control (dualtasking paradigm); spatio-temporal gait analysis and fall prevention.
