Associate Professor of Inorganic Chemistry

Matthew Cranswick, Ph.D.


B.S. Chemistry, Oregon State University, 2001

Ph.D. Inorganic Chemistry (John H. Enemark and Dennis L. Lichtenberger), University of Arizona, 2008

NIH NRSA Postdoctoral Fellow (Lawrence Que, Jr), University of Minnesota – Twin Cities, 2008 - 2012

Research Interests

Since joining CSU-Pueblo in 2012, research in the Cranswick lab has primarily focused on (1) understanding the reaction mechanisms of unusual tungstoenzymes using model complexes, (2) developing new ligand systems that reproduce key geometric and electronic properties of metalloenzymes, and (3) developing photocatalysts for small molecule activation.
