Biography

I am a research scholar at Princeton University in the Princeton Computational Imaging Lab. I am also a research assistant professor at UNC Chapel Hill and visiting faculty at IIT Madras. I obtained my PhD from UNC Chapel Hill, under the advise of Prof. Henry Fuchs, on next generation novel near-eye displays for virtual and augmented reality. My research interests lie at the intersection of optics, perception and graphics. Prior to joining UNC, I obtained my B.Tech and M.Tech degrees in Electrical Engineering, with a specialization in Signal Processing, all from IIT Madras. I have previously held research internship positions at Facebook Reality Labs, Microsoft Research Cambridge, NVIDIA Research and I was also a visiting researcher at the Fluid Interfaces Group of MIT Media Lab and CoSMIC lab of NUS,Singapore.
