Diana K. Bayer

Diana K. Bayer, DO is a Clinical Associate Professor in the Department of Internal Medicine at the University of Iowa with dual appointments in Pediatrics (Rheumatology, Allergy and Immunology) and Immunology. She serves as Associate Director of the Allergy/Immunology Fellowship Program and maintains clinical practice at University of Iowa Hospitals and Clinics.

Her educational background includes:

• BA in Biology from University of Northern Iowa
• DO from Des Moines University College of Osteopathic Medicine
• Pediatrics residency at Wayne State School of Medicine/Children's Hospital of Michigan
• Allergy/Immunology fellowship at Baylor College of Medicine/Texas Children's Hospital

Dr. Bayer's research focuses on genetic mechanisms of primary immunodeficiency disorders and novel allergic disease pathways, with particular emphasis on OSMR variants, STAT1 mutations, and emerging food allergens. Her work bridges pediatric and adult immunology through molecular investigations of atopic conditions and population health studies on allergy management.

Analysis of her 2023-2025 publications reveals three dominant research trajectories: 1) Discovery of novel genetic variants causing severe immunological phenotypes (e.g., OSMR, NFE2L2), 2) Clinical characterization of understudied immunodeficiency syndromes across age groups, and 3) Public health initiatives addressing epinephrine accessibility in schools and identification of emerging food allergens like amaranth.

In her role as Fellowship Program Associate Director, Dr. Bayer actively mentors trainees through the FACE (Faculty/Fellows as Clinician Educators) Program and contributes to the Master Clinician Program. She maintains clinical operations in E212 General Hospital with direct patient scheduling and collaborates extensively across hematology, infectious disease, and pediatric subspecialties.
