Combined Adult and Pediatric Infectious Diseases Fellowship

Designed for medicine/pediatric trained physicians who desire fellowship training in both adult and pediatric ID, who have demonstrated an interest and aptitude for research, and who desire a research-focused academic career. Training consists of one year of adult ID clinical training, one year of pediatric ID clinical training, and two years of research training via either an adult or pediatric-based research project. The clinical and research training schedule is tailored to each combined adult/pediatric ID fellow. The research training is supported by either the Adult ID T32 training grant, the Pediatrics ID T32 training grant, or the Global Health Fellowship program. Graduates of this combined fellowship will be eligible for board certification in Adult Infectious Diseases and Pediatric Infectious Diseases.

Candidates are encouraged to contact either fellowship program early in the process to help facilitate the logistics of working with two independent match systems.

If you have an interest in this program, please contact either the fellowship program coordinator for adult ID Betsy Wehrwein ( or pediatrics ID Lindsey Christ (
