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 are 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 the University of Delaware (UD) Microbiology Graduate Program address these challenges in five separate colleges and thirteen departments. By bringing these faculty and resources together to train the next generation of microbiologists, with stakeholder guidance to develop an innovative educational program, the Microbiology Graduate Program serves as a model for interdisciplinary enterprises at UD.

The interdisciplinary approach of UD’s microbiology graduate program was a big appeal for doctoral students Austin Morgan (left) and Rene Hoover.

Read about how the UD microbiology graduate program investigated how a bacteria naturally found in the soil that is beneficial to human health can enhance the levels of the amino acid and antioxidant ergothioneine in spring wheat in UDaily.

The goals of this graduate program are to:

  • Recruit and support a diverse pool of high-quality graduate students in Microbiology
  • Support diverse Microbiology faculty invested in cutting-edge student training
  • Rigorously deliver foundational concepts in genome-enabled Microbiology via a core curriculum
  • Provide rigorous electives to support broad exploration beyond the core curriculum
  • Foster professional skills in trainees, enabling them to succeed in multiple career paths
  • Facilitate cross-departmental and cross-college research collaborations

  • RENEE HOOVER

    Ph.D. student, Microbiology

    “The interdisciplinary support, with access to experts in many fields at UD, has been crucial for my research on freshwater bacteria that oxidize iron which can help us improve soil and water quality.”
