Biography
I am an Assistant Professor at School of Computer Science, University of Petroleum and Energy Studies, Dehradun, India. My research work lies 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 Ph.D. and M.Tech. in Medical Imaging and Informatics at IIT Kharagpur, India. There I studied holographic imaging with Prof. Pranab K Dutta (EE Professor at IIT Kharagpur). During my postdoctoral career, I have worked at SMART (MIT’s research enterprise), both at Singapore and USA locations. There I studied caustic wavefront encoding with Prof. Rajeev J Ram (EECS Professor at MIT). During my postdoctoral career, I have also worked at Caltech, USA, where I studied signal processing algorithms for photoacoustic imaging.
