Microbiology & Immunology

What you'll do in college

This field is all about the microscopic organisms that run the world—and the immune systems trying to fight them off. Coursework dives deep into bacteriology, virology, immunology, epidemiology, and microbial genetics.

Labs require meticulous sterile technique: you'll spend countless hours streaking agar plates, Gram staining, growing cultures in the incubator, and running assays to see how cells respond to pathogens without accidentally contaminating your bench (or yourself).

What you'll do after college

Grads work in public health (CDC, state labs), biopharma, clinical diagnostics, and food or environmental safety testing. The rise of mRNA vaccines and immunotherapy has made this a booming sector.

Entry-level roles often involve bench work, quality control, or clinical lab testing. Many grads go on to medical school, veterinary school, or PhD programs to become principal investigators, virologists, or infectious disease specialists.
