    Lab Name: Neurovascular Coupling Laboratory



    Our laboratory aims to understand the basic mechanism of physiological interaction among neurons, glias and vascular system and provide better insights for perfusion related neuroimaging techniques. Our particular research interests include: 1) Study the effect of chronic stress on neurovascular coupling at functional and structural level, 2) Study  the effect of pathologically heightened neuronal excitation and synchronization on neurovascular coupling at functional and structural level and develop cell-therapy for epilepsy, 3) Study neurovascular coupling mechanism through neurovascular coupling modulators, such as nitric oxide, carbon monoxide, & glucose, and 4) Develop novel techniques to restore neurovascular coupling dysfunction

    We use light as a tool to understand and manipulate living biological system, aiming to address pressing problems in neuroscience. Our research theme includes but is not limited to intravital imaging techniques, optical neuromodulation, and bio-integrated photonics. We take multidisciplinary approaches integrating optics, engineering, and biomedicine.

    Modern high-field MRI provides unparalleled sensitivity and quantification accuracy for measurement of physical properties and processes of a living human body. In brain imaging, diffusion weighted imaging and quantitative susceptibility mapping are already widely used to map and measure water diffusion constant and magnetic susceptibility of grey and white matter, with a prospect of applying them as a quantitative biomarker for disease diagnosis. Our laboratory is interested in developing new methodologies for MRI to advance the magnetic resonance-based in-vivo physical property measurement and mapping. A strong emphasis is placed on solid understanding of the physics of MRI hardware and contrast generation, and translation of the research outcomes to clinical practices applied to local population.

    Our laboratory focuses on design and structural characterization of supramolecular protein assemblies that can be toward to make cellular and molecular therapies effective and practical approaches eventually to treat disease. Protein-based biomaterials designed by utilizing the tools of De Novo protein design (rational and computational designs) are used to study the mechanisms by which chemical or mechanical signals are sensed by cells and alter cell function. These biomaterials that interface with nanoscience are used to deliver drugs safely and efficiently; to prevent, detect, and treat disease; to assist the body as it heals; and to engineer functional tissues outside of the body for organ replacement. Our biomaterials are now designed rationally or computationally with controlled assembly structure and dynamic functionality to integrate with biological complexity and perform tailored, high-level functions in the body. Design of new biomaterials provides desirable cues in a variety of tissue engineering, immunotherapy and drug delivery to promote the regeneration or targeted destruction of tissues and organs in the body.
