Faculty Profile


Dr Kenneth Jonnson

Dr. Kenneth Jonnson, Assistant Professor, and Biological and Physical Sciences Program Coordinator


Office: 606-N
Phone: 713-221-2720




Dr.. Johnson has been at UHD since 2002 and currently serves as Assistant Professor in Geology and Chemistry in the Department of Natural Sciences. He is a geologist who specializes in petrology and geochemistry, and studies the formation and evolution of silicate magmas, the origin of metallic ore deposits, and the tectonics of continental orogenic events. He teaches courses in physical geology, mineralogy, petrology, and inorganic geochemistry
