Microbiology: Exploring the unseen world Microbiology represents a spectrum of interests from basic science to biotechnology to infectious disease. Microbes cause the infectious diseases that are some of our biggest foes, yet are also our closest companions, with microbial cells outnumbering human cells in our bodies. They are the engines that drive the biosphere and shape our climate. Our research portfolio includes microbial physiology, molecular microbiology, genetics, genomics, symbiosis, pathogenesis, biotechnology, computational biology, and ecology. Graduates of our program go on to jobs in health care, public health, science policy, food safety, pharmaceuticals, industrial microbiology, and scientific research at academic and government institutions.
