WHY I’M HERE: How do biological organisms create a useful and dynamic visual representation of the surrounding environment? This question has been asked from the perspectives of several scientific disciplines, yet it is still largely unknown how signals from photoreceptors ultimately result in visual perception. The vision science program at UC Berkeley is the ideal location for a multidisciplinary approach to vision science, offering a breadth in curriculum and research experience with exceptional mentorship.
MY RESEARCH: The number of photoreceptor cells vastly outnumber the optic nerve fibers carrying the visual signal from the retina to the brain. In this sense, the optic nerve can be viewed as an “information bottleneck,” and the retina as an image compressor that extracts only the useful information from the retinal image to send to the visual cortex. My research in the Roorda lab is focused on better understanding the visual signal at the output of the retina, where the receptive fields of retinal ganglion cells impose the spatial and temporal constraints of input to the visual cortex. Specifically, my research uses psychophysical experimentation and quantitative analysis in combination with advanced retinal imaging and eye-tracking that is at the cutting edge of development in the Roorda lab here at UC Berkeley.
MY DREAM: To be both successful and happy!
MY HOBBIES: Reading, yoga, travel, photography
