Rice Computational Imaging Lab

Aug 2018 - Present


I currently work in the Rice Computational Imaging Group. My advisor is Prof. Ashok Veeraraghavan. My research focuses on the codesign of optical systems and image reconstruction algorithms. More specifically, I have studied how techniques such as unrolled-networks, CNN's, deep image prior, and implicit neural representations can optimize imaging systems. Applications of interest include imaging through scattering media and physics-based rendering.

Prior Research Experience

June 2012 - May 2018


As an undergraduate, I worked in the Image Science Lab under the supervision of Prof. Aswin Sankaranarayan. My project was to build a spherical lensless imager, adapting the prior work on flatcam to the non-planar domain. Prior to working with Prof. Sankaranarayanan, I also worked with Dr. Nisha Shukla, studying how gold nanoparticles (shown on the left) could be used in enantiomeric separation. In high school, I had also worked in several labs, including: Professor Miriam Rafailovich developing bactericidal surfaces using graphene; Professor Swastik Kar studying the gas sensing properties of graphene; and Professor Erin Cram studying gene expression in C. elegans.
