    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.

    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.

    Current Research and Scholarly InterestsWe study natural cellular mechanisms for adapting to genetic change. These include systems activated during normal development and those for detecting and responding to foreign or unwanted genetic activity. Underlying these studies are questions of how a cells can distinguish information as "self" versus "nonself" or "wanted" versus "unwanted".

    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.

    Current Research and Scholarly InterestsClinical neuro-oncology: My research explores the epidemiology, natural history, and disease patterns of brain tumors and other cancers in childhood, as well as prospective clinical trials for treating these neoplasms. Research interests also include neurologic effects of cancer and its therapies.

    Current Research and Scholarly InterestsDr. Fisher is interested in clincal, laboratory and translational aspects of epilepsy research. Prior work has included: electrical deep brain stimulation for epilepsy, studied in laboratory models and clinical trials; drug delivery to a seizure focus; mechanisms of absence epilepsy studied with in vitro slices of brain thalamus; hyperthermic seizures; diagnosis and treatment of non-epileptic seizures, the post-ictal state; driving and epilepsy; new antiepileptic drugs; surgery for epilepsy.

    Current Research and Scholarly InterestsMy research encompasses several translational projects. One focus is to modify the routine audiologic test battery such that it places equal weight on hearing acuity and hearing function. This work includes measures of speech in noise, or electrophysiologic responses such as the FFR. I also explore tools to better assess and maximize performance in users of hearing aids and cochlear implants. Finally, I am also investigating the benefits of telemedicine, and new treatments for tinnitus.
