Tim Bahr, MS, MD

Tim Bahr, MS, MD

Residency: Phoenix Children’s Hospital

Dr. Bahr’s research is in neonatal hematology. He is mentored by Dr. Robert Christensen.  His current projects are focused in three areas: (1) discovering genetic causes of acute bilirubin encephalopathy (https://www.kernicterus-registry.org) and studying innovative tools for diagnosis and management of hyperbilirubinemia (BiliCam and CoSense); (2) evaluating the diagnostic utility of new red blood cell indices measured by automated heme analyzers in neonates (e.g. fragmented red cells, reticulocyte hemoglobin, etc.); and (3) describing the Erythropoietin/Erythroferrone/Hepcidin axis in neonatal and preterm populations. He has a special interest in ferritin and its role in iron metabolism.

Sam Bircher, MD

Sam Bircher, MD

Residency: Oregon Health & Science University

Dr. Bircher grew up in North Carolina and attended Virginia Tech Carilion School of Medicine. He completed his pediatric residency at Oregon Health & Science University. The breadth of acuity and opportunity to intervene at such an important juncture in a patient’s life lead him to pursue a career in Neonatology. He is working in the Yost lab, where his research focus is on specific inflammatory cell death processes in neutrophils (NETosis) and macrophages (pyroptosis). Dysregulation of these forms of cell death leads to significant inflammatory tissue damage, making them intriguing therapeutic targets in a wide range of diseases including neonatal sepsis.

Second-Year Fellows

Whitley Hulse, MD

Whitley Hulse, MD

Residency: University of Colorado

Dr. Hulse was born and raised in Kansas until she ventured out west for residency in Colorado and a little further west to Utah for fellowship.  She has two children: her fur baby named Konza and her son named Hudson.  Along with her husband, Andrew, she has enjoyed everything that Utah has to offer, from gorgeous national parks to award-winning ski slopes.

Dr. Hulse’s research interest is in neurodevelopmental outcomes.  Many of the practices of the NICU can negatively affect the neurodevelopmental outcomes of the infant.  Thus, she has teamed up with her research mentors, Dr. Robert Christensen and Dr. Tara Dupont, to investigate any NICU practice than can positively affect brain growth and development.  Her current investigations include describing the Erythropoietin/Erythroferrone/Hepcidin axis to improve how we evaluate iron metabolism for blood production and brain growth.  Additionally, she is investigating the utility of early intervention to determine if there are clinical outcomes, such as the severity of the gross motor assessment (GMA), which would increase parental follow up for long term neurodevelopment.  Dr. Hulse has additional interest in point-of-care ultrasound (POCUS).  She is beginning a project with Dr. Belinda Chan on using abdominal ultrasound in the diagnosis of necrotizing enterocolitis.
