Tunable photonic nanostructures for laser pulse control and dynamic imaging Abstract For decades, nanofabrication has been the driving force behind the transformations in electronics. Light-based devices currently experience a similar transition: nanostructure-based photonic elements bear promise to revolutionize several key technology areas, such as telecommunications, augmented reality, remote sensing, and imaging. In this talk, I […]
Opportunities to Improve Clinical Outcomes with Intravascular Ultrasound (IVUS) in Lower Extremity Revascularizations Abstract Peripheral vascular disorders are prevalent and mounting health conditions, particularly in light of the aging population. Both acute and chronic arterial and venous disease result in excess morbidity and mortality and dramatically reduce health-related quality of life. Yet, despite the expanded […]
Technology Transfer and Entrepreneurship at UCI Abstract This seminar will discuss “technology transfer”, the process by which UCI (1) protects intellectual property (inventions and software) developed by its faculty, staff, researchers and grad students; and (2) commercializes this IP through licensing to an existing company or startup. Also discussed will be the services and resources […]
FLIM and Mitometer enable metabolic profiling and tracking phenotypic changes in mitochondria in cancer cells Abstract The hallmark of metabolic alteration of increase glycolysis, i.e. Warburg effect, in cancer cells together with atypical extracellular matrix structure may be responsible for tumor cell aggressiveness and drug resistance. While it is it known that tumor cells stiffen […]
Cardio-oncology; Advanced optoacoustic imaging methods for biomedical research and clinical diagnostics Abstract Optoacoustic imaging has achieved remarkable progress over the last decade, benefiting from coordinated developments in optical and ultrasound technology, probe chemistry, and imaging theory. The technique is increasingly attracting attention of the biomedical research community due to its excellent spatial and temporal resolution, […]
Environmental and Fiber Sensing with Structured Light Abstract Structured light is being widely used to revolutionize the technologies used in optical trapping, microscopy, astronomical metrology, optical communication, quantum information systems, and many others. One defines an optical wavefront that has been spatially shaped in its phase, polarisation or intensity as structured light. Prof. Lavery will […]
Tunable infrared structured laser generation and opto-thermal trapping of micro/nano particles Abstract This talk covers the experimental research and theoretical investigation of mid-infrared tunable optical vortex sources with versatile orbital angular momentum (OAM) and opto-thermophoretic trapping of micro and nano particles with mid-infrared fiber lasers. As a typical structured light, optical vortex with a helical […]
Deep Learning Applications in Biomedical Imaging Abstract Recently developed deep learning techniques revolutionized image analysis methods in the last decade. Classification, segmentation, quantitative prediction, and generating new data can be performed by the training of deep learning models. These tasks can directly be applied to biomedical imaging and successful applications will provide strong advantages to […]
Staining-free optical imaging techniques toward digital histopathology Abstract The histological optical imaging is a gold standard method to observe the biological tissues, which follows routine process such as dissection, embedding, sectioning, staining, visualization and interpretation of specimens. This technique has a long history of development, and is used ubiquitously in pathology, despite being highly time […]
Light Treatment of Alzheimer’s Disease Abstract Photobiomodulation, by utilizing low-power light in the visible or near-infrared spectrum to trigger biological responses in cells and tissues, has been considered as a possible therapeutic strategy for Alzheimer’s disease (AD), while its specific mechanisms have remained elusive. Here, we provide evidence that cognitive and memory impairment in an […]
