As a board-certified neurosurgeon, Dr. Sakatani focuses on dementia prevention and brain function research using NIRS and AI, earning the Japan Medical Association’s Medical Research Encouragement Award. He holds prominent positions in academic societies, including President of the ISOTT (2023).Kazuto Masamoto, Ph.D. (Biomedical Engineering, is Vice-President (Globalization) and Professor of the Graduate School of Informatics and Engineering, Center for Neuroscience and Biomedical Engineering (CNBE). Director of the International Education Center, UEC. Associate Editor of GeroScience. [Interests] Biomedical imaging, Bigdata image analysis, Brain microcirculation and neurovascular couplingYukio Yamada, PhD is a Professor Emeritus and Visiting Professor at Center for Neuroscience and Biomedical Engineering, The University of Electro-Communications, and a Project Researcher at Graduate School of Frontier Sciences, The University of Tokyo in Japan. His research fields are biomedical photonics and biomedical thermal engineering, particularly focusing on diffuse optical tomography, fluorescence diffuse tomography as well as theory of diffuse light propagation. He has authored or co-authored over 180 research papers, book chapters, and reviews.Felix Scholkmann, PhD is a lecturer at the University of Zurich and the head of a research group at the Biomedical Optics Research Laboratory (Dept. of Neonatology) of the University Hospital Zurich, University of Zurich in Switzerland, and at the University of Bern in Switzerland. His research primarily focuses on neurophotonics and biomedical signal processing, as well as integrative neuroscience and physiology. He has authored or co-authored over 150 research papers, book chapters, and reviews.Joseph C. LaManna, PhD is The Jeannette M. and Joseph S. Silber Professor for the Study of Brain Sciences in the Department of Physiology & Biophysics at Case Western Reserve University. He has been a member of ISOTT since 1974 and served as Past President of the Society (2009).  He is the Series Editor of the ISOTT Proceedings. He has been involved in cerebrovascular research for 40 years.  His research is concerned with brain metabolism, energy and cerebral blood flow, angiogenesis and neurodegeneration. The role of these mechanisms in tissue response to pathological insults (stroke, cardiac arrest and resuscitation, hypoxia) is being actively investigated.  His recent research has centered on ketones, cerebral angiogenesis and the role of hypoxia-inducible factor-1 in physiological adaptation to hypoxia, neuroprotection and ischemic preconditioning.  He has authored or co-authored over 200 research papers and review chapters.
