    Introduction to our lab:

    Welcome to our interdisciplinary research laboratory, a hub where cutting-edge spectroscopic magnetic resonance and fluorescence microscopy technologies converge to unravel the intricate interactions between molecules. Our lab's research spans both experimental and theoretical work. The current focus areas include:

     

    • Quantum Statistical Mechanics for ESR Spectroscopy: We delve into the quantum realm to understand and apply principles of statistical mechanics in electron spin resonance (ESR) spectroscopy, enhancing our ability to interpret complex molecular behaviors.
    • Biological Molecules in Nano-scale Spaces of Nanomaterials: This area explores how biological molecules behave and interact within the confined spaces of nanomaterials, shedding light on the nano-bio interface.
    • Dynamic Structures of Water Clusters and Confined Water: We investigate the unique properties and dynamics of water clusters and water in confined environments, crucial for understanding numerous biological and chemical processes.
    • Biophysics of BCL-2-mediated Apoptosis: Our research in this area aims to unravel the intricate molecular mechanisms of apoptosis, particularly focusing on the role of the BCL-2 protein family.
    • Biological Chemistry of Diiron Protein Family: We study the diiron protein family's role and mechanisms in biological systems, contributing to a deeper understanding of their function in various physiological processes.
    • Membrane Protein Channels or Transporters: This research area focuses on understanding the structure and function of membrane protein channels and transporters, which are vital in cellular communication and transport.
    • Single-Channel Recording of Ligand-gated Ion Channels: We employ advanced techniques to record and analyze the activities of ligand-gated ion channels at the single-channel level, offering insights into their roles in cellular signaling.
    • Enzyme design and optimization using machine-learning approaches: We employ advanced machine-learning approaches to design new or optimize enzymes for chemical transformations not found in nature.

     

    Our lab is deeply invested in studying problems in physical chemistry and biophysics using Electron Spin Resonance (ESR). By analyzing the ESR spectra of spin labels, we delve into the dynamics of local environments where spin probes reside. Spin label ESR techniques have recently emerged as powerful tools in biophysics, offering unique insights into molecular dynamics and interactions.

     

    Our ambition extends to refining ESR techniques and theories for lineshape interpretations, enhancing their capability to capture dynamic processes in ensemble systems, especially in biologically complex matrices. This endeavor is vital in advancing our understanding of biological systems at the molecular level.

     

    In an era where Cryo EM, XRD and NMR have elucidated many static structures of crucial proteins, our lab is fascinated by questions of the post-proteomic era: How do these proteins perform conformational changes to form biologically functional complex domains? What are the dynamic structures of these functional domains during the processes? Spin-label ESR is a forward-thinking chemical tool developed to explore these pioneering questions. Its applications extend to drug chemistry, drug design, chemical biology, and the development of micro-nano biomachinery systems. Our contributions in both fundamental science and bioengineering are expected to play a significant role in these fields.

     

    Our lab is equipped with various spectroscopic instruments, Mac computing workstations, and a suite of chemical biology laboratory equipment. Students interested in chemistry will have opportunities to learn programming, spectroscopic analysis, perform various spectroscopy experiments, and engage in theoretical research, laying the groundwork for a career in advanced scientific research. Many of our Ph.D. graduates have secured postdoctoral positions in top universities in the USA and Japan, continuing their studies abroad.

     

    We welcome students interested in physical chemistry or experimental work in chemical biology to join our dynamic and innovative research team!
