Liang Feng
Associate Professor of Molecular and Cellular Physiology and, by courtesy, of Structural Biology
Current Research and Scholarly InterestsWe are interested in the structure, dynamics and function of eukaryotic transport proteins mediating ions and major nutrients crossing the membrane, the kinetics and regulation of transport processes, the catalytic mechanism of membrane embedded enzymes and the development of small molecule modulators based on the structure and function of membrane proteins.

Benjamin Scott Crocker Professor of Human Biology, Emeritus
Current Research and Scholarly InterestsIn the course of evolution,two of the strongest selective forces in nature,light and sex, have left their mark on living organisms. I am interested in how the development and function of the nervous system reflects these events. We use the reproductive system to understand how social behavior influences the main system of reproductive action controlled by a collection of cells in the brain containing gonodotropin releasing hormone(GnRH)

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.

James Ferrell
Professor of Chemical and Systems Biology and of Biochemistry
Current Research and Scholarly InterestsMy lab has two main goals: to understand the regulation of mitosis and to understand the systems-level logic of simple signaling circuits. We often make use of Xenopus laevis oocytes, eggs, and cell-free extracts for both sorts of study. We also carry out single-cell fluorescence imaging studies on mammalian cell lines. Our experimental work is complemented by computational and theoretical studies aimed at understanding the design principles and recurring themes of regulatory circuits.

David Fiorentino, MD, PhD
Professor of Dermatology
Current Research and Scholarly InterestsFrom a clinical standpoint, I am particularly focused in the care of patients with myositis or systemic sclerosis. We offer clinical trials, including novel, cutting-edge cellular-based (e.g. chimeric antigen receptor, or, CAR T) therapies for these diseases. We are particularly interested in understanding the role of auto antigens in providing windows into disease pathogenesis, as well as their potential direct role of autoantibodies in causing disease.

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. -
