Three Core Research Areas

The IMP program is organized around three interconnected research pillars that collectively address the full spectrum of immunological science, from fundamental mechanisms to disease applications.

Immunobiology

The Immunobiology research area investigates the fundamental mechanisms of immune response, including how the immune system recognizes and responds to pathogens, how immunological memory is established and maintained, and how immune dysregulation leads to autoimmune diseases, transplant rejection, and cancer immune evasion. Faculty in this area conduct research on T-cell biology, B-cell differentiation, innate immunity signaling pathways, and the development of immune-based therapies for cancer and autoimmune conditions.

Pathogenesis of Infectious Disease

This area focuses on the complex interactions between hosts and microbial pathogens, investigating how bacteria, viruses, parasites, and fungi cause disease and how the immune system mounts protective responses. Research in this area directly informs vaccine development strategies, antimicrobial therapeutic approaches, and public health interventions for infectious diseases ranging from influenza and HIV to emerging viral threats. The proximity to the CDC provides unique opportunities for translational research connecting laboratory discoveries to public health applications.

Molecular Virology

The Molecular Virology area examines viral biology at the molecular level, including viral genome replication, protein structure and function, viral assembly and packaging, and the effects of viral infection on cellular proliferation and programmed cell death (apoptosis). Understanding these molecular mechanisms is essential for developing antiviral therapies, designing vaccines, and predicting viral evolution—all areas where Emory researchers have made seminal contributions.

Curriculum and Training Timeline

The IMP curriculum follows a carefully structured timeline designed to build scientific competence progressively while giving students increasing independence in their research.

During the first year, students complete core courses in biochemistry, biostatistics, immunology, and virology while simultaneously conducting three 8-10 week laboratory rotations. These rotations allow students to explore different research groups, learn diverse experimental techniques, and identify the dissertation mentor with whom they will conduct their thesis research. By the end of the first year, students have selected their primary research laboratory.

The second year introduces advanced courses in immunology and pathogenesis, a grant writing course that teaches students to formulate and communicate research proposals in the NIH format, and preparation for the comprehensive oral examination. Students also select their dissertation committee and submit an NIH-style grant proposal, developing the scientific writing and critical thinking skills that are essential for independent research careers.

Years three through six are dedicated primarily to dissertation research, during which students develop original research questions, design and execute experiments, publish findings in peer-reviewed journals, and present their work at national and international conferences. The program also requires participation in the TATTO teaching training program for one semester, ensuring that graduates are prepared for the teaching responsibilities that accompany academic careers.

Throughout the program, students participate in weekly seminar series featuring world-class invited speakers and student research-in-progress presentations. These seminars provide exposure to cutting-edge research across immunology and related fields while developing students’ abilities to critically evaluate scientific work and present their own findings to expert audiences.

Faculty and Research Excellence

The IMP program’s faculty includes some of the most distinguished immunologists in the world. Among them is Rafi Ahmed, PhD, Director of the Emory Vaccine Center and member of the National Academy of Sciences. Dr. Ahmed’s groundbreaking research on immunological memory, T-cell exhaustion, and the PD-1 pathway has fundamentally shaped our understanding of how the immune system responds to chronic infections and has directly informed the development of cancer immunotherapy drugs. His receipt of the Robert Koch Award underscores the translational impact of his work.

The program’s faculty span nine departments, creating an unusually broad base of expertise for doctoral training. This multi-departmental structure means that students can access mentorship and collaboration opportunities across diverse research areas, from structural biology and genomics to clinical immunology and epidemiology. The inclusion of CDC scientists as program faculty further expands the range of expertise available to students, connecting basic research with applied public health science.

Faculty research strengths are particularly notable in vaccine development, where Emory researchers have contributed to advances in HIV, influenza, Ebola, and COVID-19 vaccine science. The Emory Vaccine Center serves as a hub for translational immunology research, providing IMP students with access to clinical trial infrastructure and translational research pipelines that bridge the gap between laboratory discovery and human application.

CDC Proximity and Yerkes Research Center

Perhaps no other PhD program in immunology offers the geographic and institutional advantages of Emory’s IMP program. The university’s campus is located directly adjacent to the Centers for Disease Control and Prevention (CDC), the nation’s leading public health agency. This physical proximity creates opportunities for collaboration, shared seminars, joint mentorship, and access to unique research resources that are simply unavailable at other institutions.

Several CDC scientists hold adjunct faculty appointments in the IMP program, serving as dissertation committee members, collaborators, and mentors. This connection to federal public health research provides students with perspectives on disease surveillance, outbreak response, and population-level epidemiology that complement the laboratory-based research conducted in university settings. For students interested in careers at the intersection of basic immunology and public health, the Emory-CDC partnership is unparalleled.

The Yerkes National Primate Research Center, one of only seven federally funded National Primate Research Centers in the United States, provides IMP students with access to non-human primate models for vaccine and immunology research. These models are critical for translational studies that cannot be conducted in cell culture or small animal systems, enabling research on vaccine efficacy, immune aging, and pathogen-host interactions in species that closely resemble human biology. The Emory Vaccine Center, housed within Yerkes, further amplifies these research capabilities.
