    Talk Title: High Precision Photocoustic Neural Stimulation

    Abstract: Neuromodulation at high precision poses great significance in advancing fundamental knowledge in the field of neuroscience and offering novel clinical treatments. Here we reported our research on developing the photoacoustic neural stimulation as a high precision, genetic free and highly efficient technology in vitro and in vivo. Specifically, various platform technologies, including fiber emitters, films, nanotransducers and optic-generated focus ultrasound will be discussed. Sub-100 micron precision, miniaturized and multi-functional device design, and non-invasive potential will be highlighted for brain and retina applications. New insights on the cellar mechanism was obtained using the sonogenetic method. Our work demonstrated that photoacoustic stimulation is a high precision and non-genetic neural stimulation offering various neural interfaces for understanding fundamental how brain responds to mechanical stimuli and offering new clinical treatments with improved efficacies.

    Biography: Prof. Yang obtained her doctoral degree in Chemistry from Harvard University in 2006. She worked as an associate in McKinsey & Co, a business consulting firm, before she joined Purdue University Department of Chemistry and Department of Physics as an Assistant Professor. Dr. Yang is currently an Associate Professor in Department of Electrical and Computer Engineering and Department of Chemistry at Boston University. She is also Associate Chair for Master program in Department of Electrical and Computer Engineering at BU. Prof. Yangs current research is focusing on nanomaterial-based photonics and bioelectronics for neuromodulation. Her research has been published in high profile journals, including Science, Nature, Nature communication, Matter, ACS Nano and Nano Letters. She was a NSF Career Awardee and a AIMBE fellow.
