Overview
Background
Juha Töyräs holds a position of Professorial Research Fellow in the School of Information Technology and Electrical Engineering, The University of Queensland. He is also is the Head of Research and Innovation, Kuopio University Hospital and Wellbeing Services County of North Savo, and Professor of Medical Physics and Engineering, University of Eastern Finland. He has a PhD degree in the field of medical physics and his research is focused on medical devices and sensors, medical imaging, medical signal processing and connective tissue biomechanics. Since 2004, he has been the Vice/Co-Head of the Biophysics of Bone and Cartilage research group and Co-Head of the Sleep Technology and Analytics group since it was founded in January 2017 at the Department of Applied Physics, University of Eastern Finland. The groups are relatively large (three professors, c.20 research fellows and postdocs and >60 PhD students) and productive (>750 full papers and >80 PhD theses during the last 20 years). Professor Töyräs holds research grants from various European and Australian sources. He has published 323 peer-reviewed full scientific papers and numerous abstracts in international scientific meetings. In addition, he has completed supervision of 52 PhD students and number of MSc students. His papers have been cited over 14000 times and his Hirsch-index is 63 (Google Scholar). Currently, Professor Toyras supervises (University of Eastern Finland, The University of Queensland) c.20 PhD-students and number of research fellows in various fields of biomedical engineering. In addition to scientific publications and supervised academic theses, his work has led to patents and commercialization of scientific innovations. One example of this line of research is the development of a forehead EEG-electrode set for emergency medicine. The Bittium BrainStatus EEG-electrode set is patented, CE-approved and currently in global market (https://www.bittium.com/products_services/medical/bittium_brainstatus).
