Maternal-Fetal Medicine Fellowship
Mission: The mission of our fellowship is to train highly skilled subspecialists dedicated to advancing knowledge in obstetrical, medical and surgical complications of pregnancy, and to improving both the immediate and long-term outcomes for pregnant individuals and their fetuses.
Oregon Health & Science University (OHSU) is the only academic medical center in Oregon. Its main campus is located near downtown Portland, with beautiful views of Mt. Hood and the Willamette River. The OHSU Maternal-Fetal Medicine Fellowship was established in 1982.
OHSU provides comprehensive clinical care, fosters scientific innovation, and educates the next generation of clinicians, researchers, and health professionals. The MFM Division is committed to training future leaders in maternal-fetal medicine. We offer a competitive ACGME-accredited fellowship in MFM, as well as a combined Medical Genetics and Genomics/Maternal-Fetal Medicine (MGG/MFM) program.
We seek self-motivated learners and leaders dedicated to advancing the field through clinical care, research, education and advocacy. Our fellows begin their career on Match Day into our MFM program. From the outset, we are highly engaged in each fellow's development, individualizing the fellowship experience to support their unique career trajectory while providing a strong foundation for board certification and success as an exemplary MFM specialist.

Our fellowship is designed to train clinicians who excel in research, education, and clinical care. We support a customizable curriculum that allows fellows to develop expertise in their chosen domains and cultivate leadership skills. These programs provide fellows with flexible, high-impact opportunities to tailor their training and advance their long-term career goals in research, public health, and education.
Human Investigations Program (HIP): This program is designed to enhance the skills and number of patient-oriented clinical investigators. It is targeted toward fellows and early-career investigators. Successful completion of the HIP program during fellowship can lead to either a Graduate Certificate in Human Investigations or a Master of Clinical Research (MCR) awarded by OHSU.
- Certificate in Human Investigations: A two-year, coursework-based program focused on creating clinician-researchers through an integrated clinical and translational research curriculum.
- Master of Clinical Research (MCR): Fellows who complete the two-year HIP program can add a third year to earn the three-year OHSU MCR, providing structured training for clinicians and scientists who aim to make clinical and translational research central to their careers.
Master in Public Health (MPH): Offered through the OHSU-PSU School of Public Health, with six programs and various concentrations. PSU is a national model for community engagement and academic innovation. This program prepares trainees to become future public health leaders, advancing scholarship and practice in collaboration with communities to promote health and social equity.
Education Scholars Program: A one-year certificate program designed to prepare education leaders to excel in both the scholarship of teaching and education research. This program is ideal for trainees interested in careers focused on health professions education scholarship.

Mentorship
Mentorship is a foundational pillar of our MFM fellowship. Prior to starting at OHSU, fellows are introduced to various faculty within the MFM Division, the Department of Obstetrics and Gynecology, and other disciplines to begin building meaningful professional relationships.
Scholarship Advisory Committee
Each fellow is supported by a personalized Scholarship Advisory Committee, composed of OHSU faculty and, when appropriate, external mentors. This committee provides guidance and advocacy across research, clinical development, professional growth, and career planning. The committee meets twice yearly to review progress, identify opportunities, and address any barriers to success.Fellow Support
- Monthly group fellowship meetings with Drs. Benson and Valent to share experiences, provide feedback, review program updates, and discuss fellowship-related topics
- Monthly one-on-one meetings with program leadership to support individual progress and well-being
Fellows are supported in developing clinical autonomy in both outpatient and inpatient care, as well as fetal ultrasound. MFM faculty remain readily available for supervision, teaching, and consultation. Faculty also provide ongoing mentorship throughout all phases of scholarly work, including project development, recruitment, data analysis, publication, and thesis preparation.
Many support systems are available through the institution and Graduate Medical Education. Fellows are encouraged to take advantage of these programs.
