Dr. Mackey teaches Introductory Microbiology and mentors undergraduate students performing independent research projects associated with bacteria.

Although originally trained as a circadian biologist using cyanobacteria as a model system, many of the student-led research projects explore the use of natural alternatives to antibiotics as a means to inhibit bacterial growth and biofilm formation.
