Cementing the Future

Brent Constantz, an entrepreneurial marine geologist from Stanford, believes that by mimicking the way marine organisms create shells, he can manufacture concrete in a way that traps carbon rather than spews it.

Dr. Constantz specializes in novel, high-performance cements. He is the inventor on more than 60 issued U.S. patents, as well as many pending U.S. and foreign patent applications on the subject. Prior to founding Calera, his “green” cement manufacturing company, he was the founder and CEO of three successful medical device companies: Norian, Skeletal Kinetics, and Corazon. His bone-fracture cements can be found in most orthopedic operating rooms in the Western world.

A Consulting Professor at Stanford University, Dr. Constantz has taught courses in biomineralization, carbonate sedimentology, and bone mineralization, and has conducted numerous seminars and Continuing Medical Education courses on the use of cement in bone fracture management. He serves on the board of directors of the Stanford Environmental Molecular Science Institute and is affiliated with the Woods Institute for the Environment, where his expertise is carbon dioxide sequestration in concrete and the built environment.

Dr. Constantz received B.A., M.S., and Ph.D. degrees at the University of California, and received a post-doctoral appointment at the U.S. Geologic Survey and a Fulbright Scholarship at the Weizmann Institute.
