David Stone, PhD, CTO 

Dr. Stone is the founder of Iron Shell Material Technologies and the inventor of Ferrock and Polymiron. He studied environmental iron chemistry at the University of Arizona and it was there that he made the initial discovery of Ferrock in 2006, which was subsequently patented. Since then he has focused on practical applications of the Iron Carbonation Process for multiple benefits including carbon capture and solid waste recycling as well as product manufacture. As part of this effort, he spent 8 years doing field trials using Ferrock on the Tohono O'odham Nation funded by multi-year grants from the EPA, USDA, and NSF (totaling nearly $800,000). Since then he has invented another iron-based, carbon-negative material called Polymiron and has expanded the range of applications for these composites beyond construction. This includes utilizing the hydrogen and fuel gas by-products of the curing reactions for energy conversion systems. He now is focused full time on commercializing these green material technologies through the Iron Shell venture.

Tech Launch Arizona, The University of Arizona

Iron Shell Material Technologies has long been strongly supported by Tech Launch Arizona, the technology commercialization arm of the University of Arizona. The case manager there for Ferrock is Robert Sleeper, and he should be contacted regarding the license for Ferrock. 

Scientific Advisor

Dr. Sumanta Das

Dr. Das did the research for his PhD on the Ferrock iron carbonate binder under the direction of his advisor, Dr. Neithalath (above). His excellent work resulted in five scientific papers in peer-reviewed journals and the Dean's Prize in the College of Engineering for his dissertation. Now he is Assistant Professor in the Department of Civil and Environmental Engineering at the University of Rhode Island where he is Director of the Laboratory for Advanced Materials in Civil Infrastructure (LAMCI). There he and his students conduct research on self-sensing cementitious materials, cementitious binders for 3-D printing, CO2 utilization in construction materials, ballistic resistance,  and other topics. Dr. Das' highly productive research has resulted in almost 30 papers in the last four years.  His website is here
