Praneeth Chakravarthula, UNC

Biography

I am an Assistant Professor of Computer Science at UNC Chapel Hill. My research interests lie at the intersection of optics, perception, graphics, optimization, and machine learning. I am a Senior Member of Optica, recipient of IEEE VR Best Dissertation Award, Timothy L. Quigg Inventor of the Year at UNC, and several Best Paper and Demo Awards. I completed my postdoctoral research at Princeton University, obtained my PhD from UNC Chapel Hill, and 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.

If you are interested in a PhD, postdoc, internship or a visiting position, please contact me with your resume.
