Warren worked as a researcher for AT&T Bell Laboratories for two years and the NEC Research Institute for 12 years. Afterwards, he taught mathematics at Temple University.

Warren’s published and unpublished academic work is extensive. It includes being the first to show the non-algorithmicity of hydrodynamics and Newton’s laws, the algorithmicity of quantum mechanics, and the first to give the fundamental bounds on information flux and storage density. He also contributed to patents on optical computer memory and theoretical DNA computers (see NY Times). Warren has worked on voting theory for over a decade. He is the co-founder of The Center for Range Voting with Jan Kok. The website is one of the most extensive online resources on voting theory.
