Guy Satat

I am a PhD student and research assistant in the Camera Culture Group at the MIT Media Lab, working under the supervision of prof. Ramesh Raskar.

My research interests are imaging through scattering, time-resolved imaging, compressive imaging and computer vision.

About Me
I have experience in computational imaging, signal processing, machine learning, and optics.
In 2013 I graduated from the Technion – Israel Institute of Technology, as part of the Technion’s Program for Excellence. I received B.Sc. in Electrical Engineering cum laude and B.Sc. in Physics cum laude.
During my undergraduate studies I researched the use of Memristors (a recently discovered fundamental electronic device) for logic in future VLSI circuits and CPU architectures.
Before joining the Media Lab, I worked at Intel inc. on computer architecture, focusing on Network-on-Chip architecture.
Today I am a research assistant in the Camera Culture group at MIT Media Lab. My work focuses on novel methods for imaging through scattering media visible light (as oppose to X-ray or RF). Such methods have many advantages such as non-ionizing radiation and good contrast among different materials. To overcome the big challenge - for example to see under our skin - I am using different properties of light, which are utilized with custom hardware. These are combined with algorithms I develop, in order to resolve information hidden behind scatterers (such as tissue and fog).
