Loyola University Chicago

What you'll study

The PhD programme combines advanced coursework, laboratory rotations, mentored research and a dissertation focused on a specific topic within microbiology or immunology. Core areas of study include molecular microbiology, microbial pathogenesis, innate and adaptive immunity, host–pathogen interactions, virology, bacteriology and contemporary methods in cell and molecular biology.

Typical programme components:

• Coursework – advanced seminars and classes covering experimental immunology, microbial genetics, signal transduction, advanced biostatistics and experimental design.
• Laboratory rotations – initial rotations in multiple laboratories to identify a dissertation mentor and gain exposure to different techniques and research questions.
• Research – independent, hypothesis-driven laboratory research culminating in a written dissertation and oral defence.
• Qualifying examinations – written and/or oral assessments to confirm readiness to undertake dissertation research.
• Teaching and professional development – opportunities to develop teaching skills through assistantships and participate in seminars, journal clubs and grant-writing workshops.

Laboratory and technical training

Students gain hands-on experience with techniques such as tissue culture, flow cytometry, confocal and electron microscopy, next-generation sequencing, CRISPR-based gene editing, proteomics approaches and in vivo infection models where appropriate. The programme emphasises rigorous experimental design, reproducibility and data analysis.

Entry requirements

Applicants should normally hold a bachelor’s degree in a relevant biological science; many successful candidates hold a master’s degree or have equivalent research experience. Typical expectations include:

• A strong academic record in biological sciences, biochemistry, molecular biology or a closely related field.
• Prior laboratory research experience with evidence of practical skills and understanding of the research process.
• Letters of recommendation from academic or research supervisors who can speak to research potential.
• A personal statement describing research interests, relevant experience and career goals.
• For applicants whose first language is not English, proof of English proficiency is required.

The programme may consider other indicators of potential such as publications, conference presentations or relevant professional experience. Specific application components and any standardised test policies should be checked on the university’s admissions pages.

Career prospects

Graduates from this PhD go on to a wide range of careers. Common paths include:

• Academic research and teaching positions in universities and research institutes.
• Research and development roles in biotechnology and pharmaceutical companies, including roles in vaccine development, biologics and diagnostics.
• Positions in clinical and public health laboratories, disease surveillance and outbreak investigation.
• Scientific roles in regulatory agencies, non-governmental organisations and policy-making bodies.
• Careers in science communication, intellectual property/patent law (with further training), and management within life-science companies.

The programme’s emphasis on rigorous experimental skills, critical thinking and communication prepares graduates for both bench-focused roles and positions that require leadership, project management and cross-disciplinary collaboration.

Why study at Loyola University Chicago

Loyola offers a research environment that integrates basic microbiology and immunology with translational perspectives in health and medicine. Students benefit from close mentorship by faculty whose work spans molecular mechanisms of immunity, infectious diseases and host–pathogen biology, and from affiliations with clinical and translational research units within the university.

Research infrastructure includes shared core facilities for imaging, flow cytometry and genomics, as well as access to animal and biosafety facilities where relevant. The university’s location provides connections to Chicago’s broader biomedical community, enabling collaborations and internship opportunities.

The programme places importance on professional development—offering seminar series, grant-writing support and teaching experiences—so graduates are equipped for diverse career trajectories in academia, industry and public service. Prospective students should consult the department for details on available funding, trainee support and current faculty research interests.
