Microbiology Major


Microbiology is the study of the biology of microorganisms and how they interact with their surroundings. Microbiologists explore the diversity of microbial life and examine what allows some organisms to live in symbiotic relationship with the host organisms while others cause disease.  Specialization in the field of microbiology encompasses the study of the fundamental processes of bacteria, viruses, fungi and parasites, as well as the study of host defense systems that counter microbial infection.  Microbiologists develop techniques to identify microbes, to utilize them (e.g. to produce food and pharmaceuticals, to degrade toxic waste, etc) or to kill them when they harm.


Microbiology is the perfect curriculum for students interested in careers in research, graduate studies in science, medical school, nursing school, pharmacy school, or other health professions.  Job opportunities for microbiology graduates exist in a variety of different areas: hospitals; veterinary clinics; the food, beverage and pharmaceutical industries; agricultural production facilities; diagnostic services; consulting and insurance agencies ... the possibilities are almost limitless.  The types of jobs are as countless as the employment areas; micro graduates work as technicians, researchers, doctors and veterinarians, counselors, advisors, scientific writers, analysts, investigators, journalists, administrators, film makers, sales professionals, managers, and in many other occupations.


Our program was designed to give a well-rounded education in all phases of microbiology, bacteriology, parasitology, mycology, immunology, virology, microbial physiology, and microbial genetics.   Courses offered in the program are designed to fulfill medical and graduate school pre-requisites.   Our students are taught by experienced educators who also conduct state of the art research. Undergraduate research opportunities are available in many faculty research laboratories and provide students with the valuable and unique opportunities to work one-on-one with well known scientists.
