Associate Professor of Genetics
Current Research and Scholarly InterestsOur lab studies how intricate control of gene expression and cell signaling is regulated on a minute-by-minute basis to give rise to the remarkable diversity of cell types and tissue morphology that form the living blueprints of developing organisms. Work in the Barna lab is presently split into two main research efforts. The first is investigating ribosome-mediated control of gene expression genome-wide in space and time during cellular differentiation and organismal development. This research is opening a new field of study in which we apply sophisticated mass spectrometry, computational biology, genomics, and developmental genetics, to characterize a ribosome code to gene expression. Our research has shown that not all of the millions of ribosomes within a cell are the same and that ribosome heterogeneity can diversify how genomes are translated into proteomes. In particular, we seek to address whether fundamental aspects of gene regulation are controlled by ribosomes harboring a unique activity or composition that are tuned to translating specific transcripts by virtue of RNA regulatory elements embedded within their 5’UTRs. The second research effort is centered on employing state-of-the-art live cell imaging to visualize cell signaling and cellular control of organogenesis. This research has led to the realization of a novel means of cell-cell communication dependent on a dense network of actin-based cellular extension within developing organs that interconnect and facilitate the precise transmission of molecular information between cells. We apply and create bioengineering tools to manipulate such cellular interactions and signaling in-vivo.
Professor of Radiology (Pediatric Radiology) at the Stanford University Medical Center, Emeritus
Current Research and Scholarly InterestsAdvanced imaging, including magnetic resonance imaging, of injury to the developing central nervous system; including fetal, neonatal, infant and young child; and, including nonaccidental injury (e.g. child abuse).

Professor (Teaching) of Pediatrics (General Pediatrics), Emeritus
BioDonald Barr is a Professor of Pediatrics in the Stanford School of Medicine, and Professor by Courtesy in the Graduate School of Education. He teaches in the Undergraduate Program in Human Biology, where he helped to found Human Biology's curriculum in health policy. His research has studied the effect of the organizational structure of the U.S. medical care delivery system on the quality of primary care. He has also studied cultural and linguistic barriers to health care access for low-income patients, and factors associated with higher rates of attrition from pre-medical studies among minority students at Stanford and other universities. The fourth edition of his book, Introduction to U.S. Health Policy: The Organization, Financing, and Delivery of Health Care in America, was published in 2016. The third edition of his book, Health Disparities in the United States: Social Class, Race, Ethnicity and the Social Determinants of Health, was published in 2019. In June 2003 Dr. Barr was awarded the Lloyd W. Dinkelspiel Award for Distinctive Contribution to Undergraduate Education at Stanford University. In 2006 he received the Miriam Aaron Roland Prize, which recognizes Stanford faculty who engage and involve students in integrating academic scholarship with significant and meaningful volunteer service to society.

Associate Professor of Pediatrics (Gastroenterology), Emeritus
Current Research and Scholarly InterestsOur laboratory is interested in the pathophysiology, immunology, and epidemiology of viral gastroenteritis.
Clinical Assistant Professor, Pediatrics
Current Research and Scholarly InterestsUnderstanding how to implement real time patient-centered healthcare cost transparency in the acute care setting and how this transparency effects patient and system-level outcomes.
Understanding how to best decrease unnecessary variation in clinical care through implementation of clinical effectiveness tools.
Assistant Professor of Neurology and of Pediatrics
Current Research and Scholarly InterestsCauses of Disturbed Cognition in Pediatric Epilepsy
The Ernest and Amelia Gallo Professor, Professor of Urology, of Developmental Biology and, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly InterestsFunction of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.
