CurrentCharacterized the effects of high-frequency, low-power, focused ultrasound on neural stimulation in the retina, compared to light responses, quantified ultrasound modulation of responses to light stimulation, combined with pharmacology to isolate which neurons are being stimulated, combined with two-photon imaging of retina to quantify effects of radiation force. This non-invasive, high spatial-temporal resolution neuro-stimulation technology might be used as a retinal prosthetic, or for deep brain stimulation as a therapy for many brain disorders such as Parkinson’s, epilepsy, and depression.Built a custom, two-photon laser-scanning microscope. Performed functional two-photon imaging of a population of retinal interneurons accomplished by second harmonic generation simultaneous with ganglion cell recordings from a multi-electrode array to discover the structure of correlations between different cell types, including noise correlations which reveal functional connectivity and locations of noise sources. The ability to measure responses simultaneously from different cell populations is critical to understanding interactions between them.Lab manager, responsible for maintaining and improving lab infrastructure, training graduate students and post-docs.
