About Our Fellowship

Clinical Experience
Fellows will rotate on the inpatient infectious disease consult service for 52 weeks divided throughout the 3-year training period. A broad range of patients with an immense depth of pathology will be evaluated in the hospital including but not limited to intensive care, surgical/post-surgical, transplant and other immunocompromised hosts. Fellows will also participate in outpatient clinic experiences (approximately 15-20 half-day clinics per year) that includes general infectious disease, HIV, hepatitis C and care for the international traveler. Fellows will participate in weekly microbiology rounds and weekly conferences that review in-depth management of patients and guidelines in pediatric infectious diseases.
Research Experience

Fellows have a vast array of research training options from basic science to clinical/translational, quality improvement, collaborating with the MCW Office of Global Health as a GME Global Health Scholar, or participation in the KINETIC3 Teaching Academy as a medical education scholar. Fellows can seek out mentors from multiple different departments and divisions at MCW. Ample opportunities exist to develop skills in grant writing and allow the fellow to be competitive for local and national awards during fellowship training. The vast resources of MCW include (but are not limited to): the Clinical and Translational Science Institute, Center for Infectious Disease Research, and the School of Public Health. With up to 18 months of protected research time, all fellows are provided ample opportunity for a successful research career.

Pediatric Joint Fellowship Curriculum
The Joint Fellowship Curriculum (JFC) at the Medical College of Wisconsin is a series of longitudinal educational experiences designed to cover topics required for all pediatric fellows. While specialty-specific education is covered within each section, the JFC endeavors to cover the remainder of topics that are common to all fellowship trainees. Fellows not only gain insight on these topics from campus-wide experts, but also do so in a collaborative learning environment with their same level fellow peers from across the pediatric enterprise.

Diversity and Inclusion

At MCW and within the Department of Pediatrics, we have several programs and resources focused on fostering a diverse and inclusive environment. Our departmental and institutional focus is confronting negative perceptions and welcoming our community. Below is just a sampling of the efforts across our institutions to embed the principles of diversity and inclusion into our culture.

  • DOP Diversity, Equity and Inclusion Council | Our Diversity Council, led by Dr. Mike Levas, the DOP Vice Chair for Diversity and Inclusion, and comprised of faculty, staff, administration, and trainees, is focused on connecting with partners across our system and within the community to ensure the DOP is a diverse, equitable and inclusive employer.
  • DOP Fellowship and Residency Diversity and Inclusion Committees | In a city filled with its own diversity and rich cultural history, our fellows and residents recognize the importance of addressing diversity, health equity, and inclusion within our programs. As such, the program is proud to recognize the presence and work of its Committee for Diversity, Equity, and Inclusion.
  • DOP Unconscious Bias Training | The AAMC has partnered with Cook Ross, Inc., a leading consulting firm, to create training focused on the science behind unconscious bias to help academic medical staff and faculty mitigate disparities. Seven members of our team have earned a certification as unconscious bias trainers through Cook Ross. These trainers have translated what they’ve learned into a two-hour training for our faculty and staff. By learning how to identify and confront unconscious bias, it is possible to mitigate the impact and promote respect for all groups.
  • Trauma-Informed Workplace Training | This committee has undertaken actions including a department-wide survey and the creation of four online training modules sharing the principles of trauma-informed approach and how to recognize signs and symptoms of trauma in ourselves and others. This group started as part of Fostering Futures, a state-wide initiative aimed at infusing a trauma-informed approach into all the systems and organizations that touch the lives of Wisconsin citizens with the goal of expanding across the state to make Wisconsin the first trauma-informed state in the nation.
  • Office of Diversity and Inclusion | Established in March 2016, the MCW Office of Diversity and Inclusion (ODI) partners within MCW and with community partners to foster and drive inclusion excellence as an effective, empowering enabler of MCW mission and strategic goals.
  • Spring Festival of Cultures | The annual Spring Festival of Cultures encourages an increased awareness and celebration of the visible and non-visible identities among our MCW community. This three-day event is an opportunity to promote the fostering of diversity, inclusion and unity at MCW.
  • President’s Diversity and Inclusion Award | MCW’s President's Diversity and Inclusion Award recognizes the accomplishments of faculty, staff, students, residents, trainees, and community members in contributing to diversity and inclusion through exemplary leadership.
  • Institute of Health and Equity | The Institute for Health & Equity is focused on researching the root causes of health disparities in our communities, and advancing the best ideas to foster health equity throughout the world. We target populations with abnormally high rates of disease and injury – urban and rural alike – and then we find out why. Partnering with community health collaborators who live and work closest to the most vulnerable populations, we are making an impact on reducing those disparities, one community at a time.
  • GMF-MCW Partnership | Through their overall partnership, MCW and GMF will bring complementary expertise on a range of strategies to invest in the health, equity and economic well-being of people across Milwaukee, beginning with the neighborhoods adjacent to the new development. Guided by community priorities and data, the GMF-MCW Partnership will be a catalyst for additional investment and community impact. Together, the partners will:
    • Engage resident and community partnerships
    • Improve social determinants of health
    • Catalyze change that leverages resources and investment

Hometown: Yemen
Medical school: The University of Jordan, College of Medicine
Residency: Hamad General Hospital, Qatar
Research /Scholarly Project: My main research focus is antimicrobial stewardship and tackling the issue of antimicrobial resistance. As overuse of antibiotics is one of the main reasons for evolving resistance, I am working on a research project to assess the noninferiority of short-course antibiotics compared to the current standard duration in hospitalized children with community-acquired pneumonia. My second fellowship project is a retrospective review that focuses on the use of valganciclovir in the prevention of Cytomegalovirus (CMV) infection in Solid organ transplant patients.  
Mentor(s): Dr. Michelle Mitchell
Research interests: Antimicrobial stewardship and management of infectious disease-related complications in immunocompromised children
Interests and Hobbies: Reading, playing squash and traveling.
Why did I choose MCW for fellowship? A large academic center with diverse pathology in a city with diverse clinical cases is one of the aspects that attracted me to MCW. In addition, on my interview day, I got a glimpse of how friendly and dedicated the pediatric infectious disease team is at MCW. One of the best things about living in Milwaukee is the variety of activities one can do year-round. Including hiking, exploring national parks and lakes, the beautiful fall scenery, and the variety of food options. I was also pleasantly surprised by how friendly, and welcoming the residents of the Milwaukee area are.
