Associate Professor (Research) of Pediatrics (Stem Cell Transplantation)
Current Research and Scholarly Interests In the coming years, I plan to further determine the genetic and immunological basis of diseases with autoimmunity or immune dysregulation in children. I believe that much can still be learned from the in depth mechanistic studies of pediatric autoimmune diseases. Genomic analysis of the patients' samples has become possible which may provide a rapid indication of altered target molecules. I plan to implement robust functional studies to define the consequences of these genetic abnormalities and bridge them to the patient's clinical phenotype.
Understanding functional consequences of gene mutations in single case/family first and then validating the molecular and cellular defects in other patients with similar phenotypes, will anticipate and complement cellular and gene therapy strategies.

Current Research and Scholarly Interests Prevention of osteoporosis begins in childhood and adolescence by measures that maximize acquistion of bone mineral during the critical adolescent years. Body mass, calcium nutriture, physical activity, growth and sex steroid hormones, and genetic factors are all thought to be important determinants of bone mass although the relative contribution of each remains controversial.
Professor of Genetics
Current Research and Scholarly Interests We examine how cells communicate and function during fetal development. The work in my laboratory focuses on the establishment of specific cell fates using genomics to decipher interactions between chromatin and developmental signaling cascades, between genomes and rapidly evolving cell types, and between genomic copy number variation and gene expression. In recent years we have focused on the vastly understudied biology of the trophoblast lineage, particularly how this lineage evolved.

Associate Professor of Otolaryngology - Head & Neck Surgery (OHNS) at the Stanford University Medical Center
Current Research and Scholarly Interests Dr. Balakrishnan's research focuses on innovative ways to improve and standardize treatments and measure outcomes in complex pediatric airway and aerodigestive conditions , as well as ways to reduce treatment costs and medical errors. By improving outcomes and reducing costs, he aims to improve the value of care, while also optimizing patient and caregiver experience during the care process.

Current Research and Scholarly Interests Our 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 Interests Advanced 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) and, by courtesy, at the Graduate School of Education
Bio Donald Barr is a physician and is Associate Professor of Sociology and Human Biology, and is the founder and director of Stanford?s undergraduate curriculum in health policy. His research has included health policy and health care reform in the former Soviet Union and the effect of the organizational structure of the U.S. medical care delivery system on the quality of primary care. More recently he has begun to study 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. His book, Introduction to U.S. Health Policy: The Organization, Financing, and Delivery of Health Care in America, was recently published by Pearson Education. In June 2003 Dr. Barr was awarded the Lloyd W. Dinkelspiel Award for Distinctive Contribution to Undergraduate Education at Stanford University. This conversation focused on writing for medicine and social science.

Current Research and Scholarly Interests Function 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.

Current Research and Scholarly Interests Dr. Bejerano, co-discoverer of ultraconserved elements, studies the Human Genome. His research focuses on genome sequence and function in both humans and related primate, mammalian and vertebrate species. He is deeply interested in mapping both coding and non-coding genome sequence variation to phenotype differences, and in extracting specific genetic insights from high throughput sequencing measurements, in the contexts of development and developmental abnormalities.
