Biography
My research interests lie at the intersection of computational optics and image/signal processing, with a focus on development of technologies for affordable healthcare and social good.
I did my postdoctoral research at SMART (MIT’s research enterprise), where I studied caustic wavefront encoding with Prof. Rajeev J Ram. I did my Ph.D. and M.Tech. (Medical Imaging and Informatics) degrees at IIT Kharagpur, India, where I studied holographic imaging with Prof. Pranab K Dutta.
