Medical College of Wisconsin Pediatric Infectious Disease Fellowship

Welcome! Thank you for your interest in the Medical College of Wisconsin (MCW) Pediatric Infectious Disease Fellowship. Our goal is to provide comprehensive clinical and research training in pediatric infectious diseases that is tailored to the fellow’s previous experience, individual interests, and aspirations, in a collegial and nurturing environment that fosters intellectual curiosity, and prepares them to excel as academic researchers and clinicians. The vast resources of MCW provide ample opportunity for fellows seeking academic excellence in infectious diseases.

These opportunities include but are not limited to the Clinical and Translational Science Institute (CTSI)Center for Infectious Disease Research, Graduate School Public Health programs, and the Office of Global Health.

A Message from Our Program Director

Katie Ryan, MD, MPHWelcome to our fellowship webpage! We love our pediatric infectious disease group and Children’s Wisconsin. We also really value our personal connections with our fellows. It is incredibly important that we work with each of our fellows to make sure that we help you to achieve your dream job. This may include matching you with faculty, mentors, and programs to help you reach your pre-determined career goals. But this may also be helping you get started within the field by exploring the many different aspects of academic medicine and pediatric infectious diseases to help you find what really interests you. Please look around our site and reach out to us for any questions you may have.

This fall (Match 2025 for upcoming July 2026 positions), our program is only recruiting for combined fellows (med/peds ID or others). We will open our match back up for categorical pediatric infectious disease fellows as well starting Match 2026 (for July 2027 positions).
