Neonatal-Perinatal Medicine Fellows

Meet Our Fellows

Our Neonatal-Perinatal Medicine Fellowship lasts three years. Meet our fellows who are at different stages of their career development, and learn about their research projects.

Cristina Gutierrez, MD

Class of 2026

MD: University of Arizona in Tucson, Arizona

Residency: UCLA Mattel Children's Hospital in Los Angeles, CA

Research Mentors: Ritu Chitkara, MD, Justin Baker, MD, Seth Hollander, MD, and Melissa Scala, MD

Clinical Mentors: Ritu Chitkara, MD

Research Interests: My interest is to focus on health disparities as a contributing factor to preterm birth and how these disparities impact specific disease processes in preterm neonates. I hope to advocate for underrepresented and marginalized communities that we serve in our NICUs in order to identify barriers to care and implement early intervention


Daphne Darmawan, MD, MBS

Class of 2026

MD: Western Michigan University in Kalamazoo, Michigan

Residency: UC Davis Medical Center in Sacramento, CA

Research Mentors: Valerie Chock, MD, MS Epi, Gary M. Shaw, DrPH, Richard J. Shaw MD, and Melissa Scala MD

Clinical Mentors: Alexis Davis, MD, MS Epi

Research Interests: I am interested in exploring best practices for supporting parental mental health in the NICU and the subsequent effects on neurodevelopmental outcomes of infants. I also have an interest in health system infrastructure and actionable steps organizations can take to improve healthcare provider wellbeing.


Igbagbosanmi Olatunji, MD, MBBS, MPH

Class of 2026

MD: University of Ibadan in Ibadan, Nigeria

Residency: Michigan State University Hurley Medical Center in Flint, Michigan

Research Mentors: Jochen Profit, MD, MPH, Sonia Bonifacio, MD, Baraka Floyd, MD, and Melissa Scala MD

Clinical Mentors: Anca Pasca MD

Research Interests: I am passionate about addressing the impact of social determinants of health on neonatal outcomes and interested in research focused on advancing health equity for vulnerable infants. Additionally, I am interested in optimizing neonatal nutrition and human milk availability globally.


Andrew Parsons, MD

Class of 2027

MD: Harvard Medical School in Boston, MA

Residency: Boston Combined Residency Program (Boston Children’s Hospital / Boston Medical Center)

Research Mentors: Jonathan Reiss, MDNima Aghaeepour, MDValerie Chock, MD, MS Epi, John Kerner, MD, Chris Duggan, MD

Clinical Mentors: Meera N. Sankar, MD

Research Interests: I am passionate about neonatal nutrition - especially parenteral nutrition (PN). My primary clinical research project aims to answer whether mixed vs soy-based IV lipid emulsions are associated with distinct inflammatory profiles in preemies - as measured by cellular markers (eg leukocyte subtypes) + inflammatory mediators (eg interleukins). I am also assisting colleagues with several projects exploring: 1) whether PN formulations co-written by AI might benefit patients, 2) whether PN is associated with tighter glucose control in neonatal encephalopathy + 3) whether increased parenteral sodium is associated with better growth in babies on CRRT. On the side, I love medical education + point-of-care ultrasound.


Desiree Gutmann, MD, Drmed

Class of 2027

MD: Goethe-Universität Frankfurt am Main Fachbereich Medizin in Frankfurt, Germany

Residency: Stanford Pediatrics in Palo Alto, CA

Research Mentors: Erik Jensen, MD, John Benjamin, MD,  Valerie Chock, MD, MS Epi, Lawrence Prince, MD, PhD, and Raya Saab, MD

Clinical Mentors: Lisa Bain, MD

Research Interests: My research focuses on lung development and prematurity-related lung disease, with a long-term goal of identifying innovative strategies to prevent and treat bronchopulmonary dysplasia (BPD). Under the mentorship of Erik Jensen, I use physiological monitoring and clinical data to better characterize lung disease in premature infants. My primary project examines the relationship between intermittent hypoxemia and hyperoxemia (IHH) and BPD in a large retrospective cohort (n≈1100). To advance my translational research approach, I am pursuing basic science training under the guidance of Lance Prince. In this work, I study the differentiation of lung mesenchymal cells in a cell culture model, including analysis of cells from a rare neonatal mesenchymal tumor harboring an EGFR KDD mutation. In addition, I am involved in multidisciplinary and quality improvement efforts aimed at advancing BPD care. I am a member of the Cardiac and Respiratory Care for Infants with BPD (CRIB) team, which develops management recommendations for infants with BPD during and after their NICU stay. I also participate in a small baby ventilator management working group focused on optimizing ventilation strategies to reduce lung injury in premature infants.


Matthew Cranshaw, MD

Class of 2027

MD: University of Miami Leonard M. Miller School of Medicine in Miami, FL

Residency: Kaiser Permanente Northern California GME in Oakland, CA

Research Mentors: Sonia Bonifacio, MD, Lisa Bain, MD, and Nivedita Srivinas, MD

Clinical Mentors: William Rhine, MD

Research Interests: Quality Improvement, Congenital Heart Disease, Neonatal Brain Injury, Improving care for patients and families with Limited English Proficiency


Ryan Brewster, MD

Class of 2028

MD: Stanford University School of Medicine in Stanford, CA

Residency: Boston Combined Residency Program (Boston Children’s Hospital / Boston Medical Center)

Research Mentors: Jonathan S. Litt, MD, MPH, ScDJanene Fuerch, MDKevin Schulman, MD

Clinical Mentors: John Benjamin, MD

Research Interests: I am a health services researcher and clinical entrepreneur focused on building, scaling, and evaluating technology-enabled models of care delivery, with an emphasis on child health equity. Ongoing initiatives include operationalizing pediatric home hospital, integrating transitional and follow-up care for high-risk neonates, and expanding tele-neonatology services globally. I also study the use of artificial intelligence for medical translation and interpretation. 


Eli Cahan, MD, MSc

Class of 2028

MD: New York University Grossman School of Medicine in New York, NY

Residency: Boston Combined Residency Program (Boston Children’s Hospital / Boston Medical Center)

MS in Health Policy: Freeman Spogli Institute for International Studies and Stanford University School of Medicine

Research Mentors: Nicole Yamada, MD, MSLou Halamek, MD, FAAP, Jason Wang, MD, PhD, Paige Church, MD

Clinical Mentors: Janene Fuerch, MD

Research Interests: My research focuses on health communication and its impact on patient outcomes. At the clinical level, I study communication between (a) clinical teams, such as in neonatal resuscitation and (b) clinicians and patients, such as in palliative care discussions, in the effort of optimizing team performance and patient experience. At the systems level, I study communication between medical institutions (such as public health authorities), media platforms (including agentic AI), and patients to analyze how (mis)information is shared, received, and acted upon. 


Gabrielle Green, MD, DPhil

Class of 2029

MD: University of Cambridge School of Clinical Medicine in Cambridge, UK

DPhil: University of Oxford in Oxford, UK

Residency: Stanford Pediatrics Residency Program in Stanford, CA

Research Mentors: Jennifer Rabbitts, MDBruno Soares, MDValerie Chock, MD, MS Epi

Clinical Mentors: Anoop Rao, MD, MS

Research Interests: I am passionate about better understanding neonatal pain so that we can improve the way we manage pain in a neonatal intensive care unit setting. My primary research project aims to investigate how non-pharmacological interventions, such as massage, can alter nociceptive processing. I am also interested in examining the impact of pain on brain development using MRI.

What's it like to be a neonatology fellow at Stanford?

Our first season of NeoNarratives gets candid about the neonatal-perinatal medicine fellowship experience at Stanford. Hear from our fellows about what it’s like to partner with faculty and families in our NICUs, train at one of the top academic institutions in the U.S., and live and grow in the Bay Area.
