Primary Research:

Our lab focuses on the development of cutting-edge optical and photoacoustic technologies for high-resolution structural, functional, metabolic, and molecular imaging in vivo. Our core technology, multi-parametric photoacoustic microscopy (PAM), is uniquely capable of simultaneously imaging hemoglobin concentration, blood oxygenation, and flow at the microscopic level. Combining multi-parametric PAM and segmentation-based single-vessel analysis, we have developed an unprecedented hardware-software platform for comprehensive and quantitative characterization of the microvasculature in vivo, including the structure, mechanical properties, hemodynamics, and associated tissue oxygen metabolism. This platform opens new opportunities to study the role of microvascular dysfunction in a wide spectrum of diseases, including neurovascular disorders, cancer, and cardiovascular diseases.
