Samuel J. Yang

Samuel J. Yang joined Google Research in 2016. Prior to that, he completed a Ph.D. in Electrical Engineering at Stanford University, where his research in the labs of Karl Deisseroth and Gordon Wetzstein focused on computational imaging and display, the co-design and optimization of optics hardware and data processing alogrithms. He was supported by a NSF Graduate Research Fellowship and a NDSEG Graduate Fellowship.



Before completing my Ph.D., I received a B.S. in Electrical Engineering from Caltech, studying engineering physics and optics in Changhuei Yang's lab, and a M.S. in Electrical Engineering from Stanford, studying machine learning, image processing and computer vision.

In 2015, at Google Research, I applied deep learning methods to images as a Software Engineering Intern.

In 2014, at Google [x], I worked with optical physicists to design and implement imaging instrumentation hardware as an intern.

In 2013, at Pelican Imaging, I explored computational photography applications as a research intern.
