  • Alan Schwartz Lab

    Work in the Alan Schwartz Lab primarily focuses on obesity and sleep apnea pathogenesis, nocturnal hypoxemia in COPD, and obesity and neural control in sleep-disordered breathing (SDB). We have experience exploring the mechanisms of SBD, with an emphasis on novel approaches to the detection and management of the disorder. We’ve also tested new methods to evaluate the severity of upper airway obstruction during sleep and to treat sleep apnea.

    Research Areas: critical care medicine, sleep medicine, hypoxemia, obesity, pulmonary medicine, COPD, sleep-disordered breathing, sleep apnea

  • Alicia Arbaje Lab

    Research in the Alicia Arbaje Lab aims to help older adults maintain dignity and quality of life as they age. We are particularly interested in creating health care systems to improve safety and outcomes for older adults.

    Research Areas: safety, gerontology, health care systems

  • Alzheimer's Disease Research Center

    The goal of the Johns Hopkins Alzheimer's Disease Research Center (ADRC) is to accelerate the discovery of new treatments that are directed at the basic mechanisms of disease, and to hasten the time when effective treatments for AD and related disorders become a reality. We have a strong commitment to basic research regarding the underlying mechanisms of Alzheimer's Disease and related disorders, and how this may translate into effective treatment. We perform clinical research seeking to identify medications to delay or treat the symptoms of dementia. We also provided many educational programs for family members and professionals.

    Research Areas: dementia, Alzheimer's disease

  • Amy Knight Lab

    Research in the Amy Knight Lab focuses on methods by which information technology can improve the quality of health care. We investigate the role computer systems can play in expanding patient-doctor communication, streamlining healthcare tasks for both medical students and practitioners, and establishing a higher standard of care. Our studies have explored the effectiveness of semi-automating daily progress notes for improved documentation, peer assessment of professional performance among hospitalists, ways to enable patient-centered care using information technology and other topics.

    Research Areas: outcomes, patient-provider relationships, internal medicine, information technology

  • Anne Rompalo Lab

    Research in the Anne Rompalo Lab focuses on STD research and application. We recently examined the relationship between violence against women and HIV-related risk factors in women living in the United States. Past projects include a nine-year longitudinal observation study of HIV-infected women in Baltimore.

    Research Areas: women, HIV, sexually transmitted diseases, domestic violence

  • Antoine Azar Lab

    The Antoine Azar Lab conducts research on topics related to primary immunodeficiency diseases, allergies and lung disease. Specifically, we explore the role of primary immunodeficiency in certain difficult-to-treat chronic lung diseases, such as COPD, emphysema and asthma.

    Research Areas: emphysema, immunology, asthma, allergies, lung disease, COPD

  • Antony Rosen Lab

    Research in the Antony Rosen Lab investigates the mechanisms shared by the autoimmune rheumatic diseases such as lupus, myositis, rheumatoid arthritis, scleroderma and SjogrenÕs syndrome. We focus on the fate of autoantigens in target cells during various circumstances, such as viral infection, relevant immune effector pathways and exposure to ultraviolet radiation. Our recent research has sought to define the traits of autoantibodies that enable them to induce cellular or molecular dysfunction. We also work to better understand the mechanisms that form the striking connections between autoimmunity and cancer.

    Research Areas: myositis, lupus, rheumatology, Sjogren's syndrome, scleroderma, autoimmune rheumatic diseases, rheumatoid arthritis

  • Cynthia Rand Lab

    The Cynthia Rand Lab at the the Johns Hopkins Center for Mind-Body Research studies health care disparities, asthma and chronic obstructive pulmonary disease (COPD) therapy adherence, and outcomes and quality of life.

  • David Hellmann Lab

    Research in the David Hellman Lab focuses primarily on the rheumatic disease vasculitis. Our studies have involved evaluating patients with temporal arteritis, giant cell arteritis and Takayasu arteritis. We have also explored topics such as Wegener's granulomatosis and polyarteritis nodosa. Our research also has investigated how the detection of temporal arteritis may be impacted by other diseases, such as chlamydia pneumoniae.

    Research Areas: Wegener’s Granulomatosis, rheumatology, vasculitis, arthritis

  • Deborah Sellmeyer Lab

    Research in the Deborah Sellmeyer Lab focuses on osteoporosis, nutrition, and all metabolic bone disorders. As part of an American Society for Bone and Mineral Research task force, we provided guidance on bisphosphonates (BP) therapy duration with a risk benefit perspective. Another recent study determined that thiazolidinediones (TZD) use was associated with increased non-spine fractures in women, but not men, with type 2 diabetes.

    Research Areas: osteoporosis, nutrition, metabolic bone disorders, endocrinology
