The University of Colorado Connection

Prometheus Materials Inc., which produces a zero-carbon concrete alternative, was co-founded by four faculty members at CU Boulder: Wil Srubar, Sherri Cook, Mija Hubler (CU Boulder Civil, Environmental and Architectural Engineering) and Jeff Cameron (CU Boulder Biochemistry).
