  • Katherine Wilson Lab

    Principal Investigator:
    Katherine Wilson, Ph.D.
    Cell Biology

    Research in the Wilson Lab focuses on three components of nuclear lamina structure: lamins, LEM...-domain proteins (emerin), and BAF.

    These three proteins all bind each other directly, and are collectively required to organize and regulate chromatin, efficiently segregate chromosomes and rebuild nuclear structure after mitosis. Mutations in one or more of these proteins cause a variety of diseases including Emery-Dreifuss muscular dystrophy (EDMD), cardiomyopathy, lipodystrophy and diabetes, and accelerated aging.

    We are examining emerin's role in mechanotransduction, how emerin and lamin A are regulated, and whether misregulation contributes to disease.

  • Kelly Gebo Lab

    Principal Investigator:
    Kelly Gebo, M.D., M.P.H.
    Medicine

    Work in the Kelly Gebo Lab focuses on topics such as evidence-based practice, health utilizatio...n, policy generation, health disparities in patient access to health care, HIV/AIDS, aging and hepatitis. As part of the HIV Research Network (HIVRN), our lab gathers clinical and demographic data on HIV-infected patients to help develop a single, nationwide research database. In addition, our ongoing research explores evidence-based practice in relation to the management of hepatitis C as well as HIV/AIDS in mentally ill patients. We also investigate racial and gender disparities in patients who receive highly active antiretroviral therapy. view more

  • Neuroimaging and Modulation Laboratory (NIMLAB)

    Principal Investigator:
    John Desmond, Ph.D., M.S.
    Neurology

    The neuroimaging and Modulation Laboratory (NIMLAB) investigates neural correlates of cognition... and behavior using neuroimaging methods such as functional magnetic resonance imaging (fMRI) and neuromodulation techniques such as transcranial magnetic stimulation (TMS). We are looking in depth at the contributions of the cerebellum and cerebro-cerebellar circuits to cognition; the effects of chronic heavy alcohol consumption on cognition and brain activation underlying cognitive function; how aging in humans affects neural systems that are important for associative learning and stimulus awareness; and the integration of transcranial magnetic stimulation with functional MRI. view more

  • Ocular Motor Physiology Laboratory

    Lab Website

    Our research is directed toward how the brain controls the movements of the eyes (including eye... movements induced by head motion) using studies in normal human beings, patients and experimental animals. The focus is on mechanisms underlying adaptive ocular motor control. More specifically, what are mechanisms by which the brain learns to cope with the changes associated with normal development and aging as well as the damage associated with disease and trauma? How does the brain keep its eye movement reflexes properly calibrated? Our research strategy is to make accurate, quantitative measures of eye movements in response to precisely controlled stimuli and then use the analytical techniques of the control systems engineer to interpret the findings.

    Research areas: 1) learning and compensation for vestibular disturbances that occur either within the labyrinth or more centrally within the brain, 2) the mechanisms by which the brain maintains correct alignment of the eyes to prevent diplopia and strabismus, and 3) the role of ocular proprioception in localizing objects in space for accurate eye-hand coordination.

  • Peter Abadir Lab

    Principal Investigator:
    Peter Abadir, M.D.
    Medicine

    Research in the Peter Abadir Lab focuses on the renin-angiotensin system (RAS), a signaling pat...hway that regulates blood pressure and has been linked independently to both aging and inflammation. We’re particularly interested in changes in RAS that occur with aging. We also study signal transduction and the role of the crosstalk between angiotensin II receptor in aging and are interested in understanding the function of angiotensin II in the process of vascular aging. view more

  • Qian-Li Xue Lab

    Principal Investigator:
    Qian-Li Xue, Ph.D.
    Medicine

    The primary area of statistical expertise in the Qian-Li Xue Lab is the development and applica...tion of statistical methods for: (1) handling the truncation of information on underlying or unobservable outcomes (e.g., disability) as a result of screening, (2) missing data, including outcome (e.g., frailty) censoring by a competing risk (e.g., mortality) and (3) trajectory analysis of multivariate outcomes. Other areas of methodologic research interests include multivariate, latent variable models. In Women's Health and Aging Studies, we have closely collaborated with scientific investigators on the design and analysis of longitudinal data relating biomarkers of inflammation, hormonal dysregulation and micronutrient deficiencies to the development and progression of frailty and disability, as well as characterizing the natural history of change in cognitive and physical function over time. view more

    Medicine

    The Sean Leng Lab studies the biology of healthy aging. Specific projects focus on chronic infl...ammation in late-life decline; immunosenescence and its relationship to the basic biological and physiological changes related to aging and frailty in the human immune system; and T-cell repertoire analysis. view more

  • Susan Michaelis Lab

    Principal Investigator:
    Susan Michaelis, Ph.D.
    Cell Biology

    The Michaelis Laboratory's research goal is to dissect fundamental cellular processes relevant ...to human health and disease, using yeast and mammalian cell biology, biochemistry and high-throughput genomic approaches. Our team studies the cell biology of lamin A and its role in the premature aging disease Hutchinson-Gilford progeria syndrome (HGPS). Other research focuses on the core cellular machinery involved in recognition of misfolded proteins. Understanding cellular protein quality control machinery will ultimately help researchers devise treatments for protein misfolding diseases in which degradation is too efficient or not enough. view more
