Why Pursue a PhD in MMI?

Upon completion of the Molecular Microbiology & Immunology Degree, students will be proficient in demonstrating knowledge and comprehension of the foundations of the immune systems in various hosts, microbial pathogenesis, host-pathogen interactions, microbial and host genomics, and biology of diseases of the immune system. Students will design and execute experiments, apply the scientific method, and apply cutting-edge knowledge and experimental tools in microbiology and immunology to solve current health challenges.

Microbiology is the study of microscopic organisms, encompassing bacteriology, mycology, parasitology, and virology. Molecular Microbiology emphasizes studies of key molecules, factors and functions in microorganisms. Multiple CMB PhD program faculty are engaged in research in this area. Immunology is the branch of science dealing with the components of the immune system, immunity from disease, the immune response, tolerance, and immunologic techniques of analysis. Multiple faculty at UTSA possess interests in the physiological functioning of the immune system, malfunctions of the immune system in immunological disorders, and the physical, chemical, and physiological characteristics of the components of the immune system.
