He returned to UC Berkeley in 2003 as a visiting scholar, and from 2004 to 2013 was with the Massachusetts Institute of Technology, including holding the Esther and Harold E. Edgerton chair in the Department of Electrical Engineering and Computer Science.
[7] He has been with Boston University since 2016, after two years with the Nest Labs division of Alphabet Inc.[8] Goyal coauthored the 2014 textbook Foundations of Signal Processing with Martin Vetterli and Jelena Kovačević, which was reviewed in IEEE Signal Processing Magazine.
[11][12] In an article published in Nature in 2019,[13] Goyal's group introduced a method for non-line-of-sight (NLOS) imaging that uses only an ordinary digital camera.
This contrasts with many earlier methods that use pulsed laser illumination and detectors sensitive to single photons.
[14][15][16] He later collaborated on work that extended laser-based NLOS imaging to 1.43 km stand-off distance.
