Dr. Oluwatobi "Tobi" Olayiwola is an allergist and clinical immunologist at HealthPartners and an Assistant Research Investigator at HealthPartners Institute. She completed her fellowship training at Brigham and Women's Hospital in Boston, following residency training in pediatrics at St. Louis Children's Hospital.

Dr. Olayiwola's clinical and research interests focus on pediatric food allergy, particularly the treatment of peanut allergy through oral immunotherapy (OIT), and the factors that influence treatment outcomes.  Her work aims to better understand how patient characteristics and treatment factors relate to desensitization and sustained remission after OIT. She is particularly interested in expanding pediatric OIR programs to younger children and patients with allergies to foods beyond peanut.

She is also interested in the application of artificial intelligence to clinical research, including machine learning in analyzing real-world electronic medical record data on patient and provider behaviors, and clinical outcomes. Across her interests, she hopes to translate scientific findings into practical strategies that improve the delivery and personalization of care for patients with allergic diseases.
