Biography
My research interests lie at the intersection of physical optics and image/signal processing. Additionally, I try to identify the bottleneck problems in biomedical sciences, which can be solved with quickly evolving optical and computational techniques.
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) degrees at IIT Kharagpur, India, where I studied holographic imaging with Prof. Pranab K Dutta.
