John S. Coleman
John matriculated in Fall 2003 after completing his B. S. in Chemical Engineering at Carnegie Mellon University in the Spring of 2003. He completed his Ph. D. studies in the Spring of 2008. John performed an experimental study of the role of copper promoters in the high temperature catalysis of water-gas shift. He also helped develop mechanistic kinetic models and computational chemistry site models for these catalysts. In addition, he performed a preliminary study of the kinetics of very low temperature water gas shift using gold-containing catalysts.
