I am advised by Prof. Dimitris Samaras. Prior to Fall '19, I was advised by Prof. Roy Shilkrot.
Currently my research is 3D estimation and texture reconstruction from single images, specifically document images. I am trying to dewarp folded/warped document images to its equivalent flatbed scanned version using an end-to-end neural network [Read more >].
My broad interest is creating novel assistive technologies using deep learning. Although my current research is in Computer Vision, I have significant experience in working with text and speech data. Check out my old projects on Speech disfluency correction, and Dark Patterns detection in webpages.
During my Masters', I have worked on Evolutionary and Nature Inspired Algorithms, advised by Prof. Haider Banka.
