Azeem Ahmad

Biography

Dr. Ahmad joined the Department of Biology at Marian University as an assistant professor of microbiology in 2016.  He has a doctorate degree from University of California Davis and postdoctoral research experience at Harvard University. His doctoral dissertation focused on ecology, physiology, and the genetics of chemoautotrophic sulfur bacteria of the genus Beggiatoa.  While at Harvard University, Dr. Ahmad had unique opportunity to sample these bacteria found at hydrothermal vents in the deep ocean. After Harvard University. Dr. Ahmad held research positions at University of British Columbia and Iowa State University.  At UBC, he was a research scientist examining the microbial ecology of ocean viruses and harmful algae.  Most recently, he studied plant pathogens of soybean and corn at Iowa State University. Currently, his research includes detection and identification of bacterial pathogens in agricultural soils, and the effect of invasive plant species on the diversity and community composition of soil bacteria in the Marian University Ecolab.
