Siddharth Somasundaram

I am a PhD student at MIT Media Lab in Cambridge, MA working with Prof. Ramesh Raskar in the Camera Culture group. My research is currently supported by the NSF Graduate Research Fellowship.

I previously graduated from UCLA Electrical Engineering in 2021, where I worked with Prof. Diana Huffaker on semiconductor nanowire photodetectors and Prof. Achuta Kadambi on computational camera design.

Research

My goal is to enable new vision capabilities by designing sensing systems that perceive the world differently from the human eye. My current interests are in single-photon and time-of-flight imaging. My research has covered applications in 3D vision, low-light, high-speed, and non-line-of-sight imaging. Selected papers are highlighted.
