Short description of the Microbiology major.


Microbiology is enjoying a lively resurgence of interest among undergraduates. First, appreciation of the tremendous diversity among bacteria has led to the sequencing of the largest number of genomes of any life form, providing the widest sweep of evolutionary relationships at the gene level. Second, understanding host-parasite interactions at the molecular level has provided new insights on the mechanism of infectious diseases and suggested new ways to prevent and treat such diseases. And third, recognition that we have only scratched the surface of the potential power of microbes through, for example, ‘genetic engineering’ and bioremediation has created an exciting future for anyone who studies microbiology.
