Vyas Akondi
Senior Research Scientist - Basic Life, Ophthalmology
Bio
My interest in optics research started during my undergraduate studies. I worked on better methods to detect the optical degradation in the images of ground-based astronomical telescopes due to atmospheric turbulence as part of my Ph.D. studies at the Indian Institute of Science. During my first postdoctoral position in University College Dublin, I developed digital methods using spatial light modulators for measuring the wave distortions in optical microscopy and vision science. Pyramid, point diffraction, Hartmann-Shack, and confocal signal-based wavefront sensors were explored. At the Institute of Optics in Madrid, as part of my second postdoctoral position, I worked on accurate optical quality evaluation techniques for patients implanted with multifocal intraocular lenses, and contributed to the development of mathematical methods and experimental validations to facilitate the demonstration of multifocal vision for prospective refractive surgery patients and contact lens wearers using a simultaneous vision simulator based on the tunable lens that works on the principle of temporal multiplexing.
Current Role at Stanford
We develop next-generation ocular imaging devices to allow non-invasive visualization of subcellular structures in the eye with the goal of building clinically useful tools that help in early disease diagnosis and monitoring.
