Microbiology: Ph.D., M.S.


Earth is microbial: bacteria, archaea, viruses, protists and fungi are the largest store of biomass on the planet and represent nearly all of its biodiversity. They store massive genetic resources that can be used to solve challenges faced by our rapidly growing human population. Microbes will be key to developing more sustainable energy generation and material synthesis, improving human health and wellness, and satisfying increased food demands of larger human populations in the face of limited environmental resources. The faculty of UD's microbiology graduate program are already addressing these challenges in five separate colleges and 13 departments. By bringing these faculty and resources together to train the next generation of microbiologists, the microbiology graduate program serves as a model for interdisciplinary enterprises at UD.
