Lab Name: Neurovascular Coupling Laboratory

Introduction

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

Neurophotonics Lab

Introduction

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.
