Rongxin Fang
Assistant Professor of Neurosurgery and, by courtesy, of Genetics
BioRongxin Fang received his Ph.D. in Bioinformatics and Systems Biology from the University of California, San Diego, under the mentorship of Bing Ren (2015–2019). During his doctoral training, he developed high-throughput genomic technologies and computational tools to map the structure and activity of the mammalian genome at large scale and single-cell resolution. He then applied these approaches to investigate how cis-regulatory elements - such as enhancers - control gene expression and drive the diverse transcriptional programs underlying cellular diversity in the mammalian brain. As an HHMI–Damon Runyon Postdoctoral Fellow at Harvard University (2019–2024), he worked with Xiaowei Zhuang. Rongxin developed and applied genome-scale, volumetric 3D transcriptome imaging methods to map the molecular and cellular architecture of the mammalian brain across evolution and aging. He also contributed to the collaboration with Adam Cohen and Catherine Dulac to integrate transcriptome imaging with functional neuronal imaging, identifying neuronal populations in the animal brain that underlie specific brain functions.

Heidi M. Feldman
Ballinger-Swindells Endowed Professor of Developmental and Behavioral Pediatrics
Current Research and Scholarly InterestsMy current research program focuses on infants born preterm, before 32 weeks gestation from two language environments: English and Spanish. The study considers how neurobiological factors, specifically properties of the white matter circuits in the brain, interact with social, psychological, and economic factors to predict language processing efficiency at 18 months of age.

Anne Fernald
Josephine Knotts Knowles Professor of Human Biology, Emerita
Current Research and Scholarly InterestsWorking with English- and Spanish-learning children from diverse socioeconomic and cultural backgrounds, our research examines the importance of early language experience in supporting language development. We are deeply involved in community-based research in San Jose, designing an innovative parent-engagement program for low-resource Latino families with young children. We are also conducting field studies of beliefs about child development and caregiver-child interaction in rural villages in Senegal. A central goal of this translational research is to help parents understand their vital role in facilitating children’s language and cognitive growth.

Katherine Ferrara
Professor of Radiology (Molecular Imaging Program at Stanford)
Current Research and Scholarly InterestsMy focus is image-guided drug and gene delivery and I am engaged in the design of imaging devices, molecularly-targeted imaging probes and engineered delivery vehicles, drawing upon my education in biology and imaging physics and more than 20 years of experience with the synthesis and labeling of therapeutic particles. My laboratory has unique resources for and substantial experience in synthetic chemistry and ultrasound, CT, MR and PET imaging.

Andrew Fire
George D. Smith Professor of Molecular and Genetic Medicine and Professor of Pathology and of Genetics
Current Research and Scholarly InterestsWhile chromosomal inheritance provides cells with one means for keeping and transmitting genetic information, numerous other mechanisms have (and remain to be) discovered. We study novel cellular mechanisms that enforce genetic constancy and permit genetic change. Underlying our studies are questions of the diversity of inheritance mechanisms, how cells distinguish such mechanisms as "wanted" versus "unwanted", and of the consequences and applications of such mechanisms in health and disease.

Current Research and Scholarly InterestsThe microbiome carries out extraordinary feats of biology: it produces hundreds of molecules, many of which impact host physiology; modulates immune function potently and specifically; self-organizes biogeographically; and exhibits profound stability in the face of perturbations. Our lab studies the mechanisms of microbiome-host interactions. Our approach is based on two technologies we recently developed: a complex (119-member) defined gut community that serves as an analytically manageable but biologically relevant system for experimentation, and new genetic systems for common species from the microbiome. Using these systems, we investigate mechanisms at the community level and the strain level.
1) Community-level mechanisms. A typical gut microbiome consists of 200-250 bacterial species that span >6 orders of magnitude in relative abundance. As a system, these bacteria carry out extraordinary feats of metabolite consumption and production, elicit a variety of specific immune cell populations, self-organize geographically and metabolically, and exhibit profound resilience against a wide range of perturbations. Yet remarkably little is known about how the community functions as a system. We are exploring this by asking two broad questions: How do groups of organisms work together to influence immune function? What are the mechanisms that govern metabolism and ecology at the 100+ strain scale? Our goal is to learn rules that will enable us to design communities that solve specific therapeutic problems.
2) Strain-level mechanisms. Even though gut and skin colonists live in communities, individual strains can have an extraordinary impact on host biology. We focus on two broad (and partially overlapping) categories:
Immune modulation: Can we redirect colonist-specific T cells against an antigen of interest by expressing it on the surface of a bacterium? How do skin colonists induce high levels of Staphylococcus-specific antibodies in mice and humans?
Abundant microbiome-derived molecules: By constructing single-strain/single-gene knockouts in a complex defined community, we will ask: What are the effects of bacterially produced molecules on host metabolism and immunology? Can the molecular output of low-abundance organisms impact host physiology?
3) Cell and gene therapy. We have begun two new efforts in mammalian cell and gene therapies. First, we are developing methods that enable cell-type specific delivery of genome editing payloads in vivo. We are especially interested in delivery vehicles that are customizable and easy to manufacture. Second, we have begun a comprehensive genome mining effort with an emphasis on understudied or entirely novel enzyme systems with utility in mammalian genome editing.
