Research<\/h2>\r\n

\r\n

\r\nOur laboratory aims to deepen our understanding of the fundamental question, \"What is life?\" While recent advancements in molecular and structural biology have significantly advanced our understanding of life phenomena, this essential question remains unanswered.

\r\nThe hallmark of our approach is the direct observation of life phenomena at the molecular level within living cells, rather than relying on imaginary illustrations or static models. To realize this vision, we are focusing on three key areas of technological development:\r\n<\/p>
\r\n

\r\n1.  High-resolution live-cell imaging techniques: Development of cutting-edge microscopy technologies to directly observe molecules functioning within living cells.<\/p>
\r\n

\r\n2.  Cell state visualization probes: Design and synthesis of innovative molecular probes to visualize dynamic changes in cellular states.<\/p>
\r\n

\r\n3.  Image analysis methods: Development of mathematical and computational methods to extract valuable information from microscopic images.\r\n<\/p>
\r\n

\r\nBy integrating these technologies and applying them to the observation of neurons, we aim to contribute to the elucidation of brain function and mechanisms of neurological disorders.

\r\nOur research is positioned at the intersection of biology, physics, chemistry, and information science. Through this interdisciplinary approach, we strive to open new frontiers in life sciences.\r\n <\/p>\r\n <\/div>\r\n

Biography<\/h2>\r\n

\r\nGraduated from the University of Tokyo, Faculty of Medicine in 1993. Medical Doctor (M.D.) and Ph.D. After serving as a JSPS Research Fellow and Assistant Professor at the same university's graduate school, became a Team Leader at RIKEN Center for Biosystems Dynamics Research (formerly known as RIKEN Quantitative Biology Center until reorganization in 2018) in 2011. Since 2016, Professor at the Department of Physics, Graduate School of Science, The University of Tokyo (concurrent position with RIKEN). Since 2020, Professor at the Department of Molecular and Cellular Biology, Graduate School of Medicine, The University of Tokyo (concurrent positions with RIKEN and Graduate School of Science).\r\n

\r\nSpecializes in cell biology and biophysics. Conducts research utilizing various imaging technologies, with a focus on optical microscopy (single-molecule imaging, super-resolution microscopy techniques).\r\n\r\n <\/p>\r\n <\/div>\r\n
