Research in the Quantitative Imaging Technologies lab — a component of the Imaging for Surgery, Therapy and Radiology (I-STAR) Lab — focuses on novel technologies to derive accurate structural and physiological measurements from medical images. Our team works on optimization of imaging systems and algorithms to support a variety of quantitative applications, with recent focus on orthopedics and bone health. For example, we have developed an ultra-high resolution imaging chain for an orthopedic CT system to enable in-vivo measurements of bone microstructure. Our interests also include automated methods to extract quantitative information from images, including anatomical and micro-structural measurements, and shape analysis.

The primary area of statistical expertise in the Qian-Li Xue Lab is the development and application 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.

Research in the Hanan Aboumatar Lab focuses on advancing patient-centered outcomes through improved patient and family involvement. We also focus on multilevel methods to increase the patient-centered focus of care delivery. Recent research examined the impact of a quality-improvement intervention on patient involvement in primary care and treatment with respect and dignity in intensive care.

Dr. Stephen Berry’s research focuses on healthcare quality, safety and costs among persons living with HIV, both in the outpatient and inpatient settings. He conducts observational and interventional studies of sexually transmitted infection screening in HIV clinics, with a focus on improving performance to meet national guidelines. He leads observational studies of rates and reasons for hospitalizations and of 30-day readmission rates among HIV patients. He is conducting a randomized study of a nurse- and pharmacist-based team to reduce inpatient HIV medication errors and increase engagement in outpatient care among persons living with HIV who are hospitalized at The Johns Hopkins Hospital.

Researchers in the Henry Michtalik Lab are interested in patient safety—particularly as it relates to patient census statistics and acute to primary care transitions—and quality improvement and systems management.

The Michelle Eakin Lab conducts research on behavioral science and adherence and asthma outcomes in inner-city children. Our studies into behavioral science have included exploring the impact of medication adherence on lung health outcomes in patients with cystic fibrosis, disparities in anti-hypertensive medication adherence in adolescents and other key topics. We also investigate methods for improving asthma care and treatment as well as health disparities among various ethnicities, particularly in pediatric patients.

Research in the Meredith McCormack Lab deals primarily with pulmonary diseases, such as asthma and chronic obstructive pulmonary disease (COPD), and the role of environmental exposures in lung diseases. We have researched the factors that contribute to inner-city asthma, with a focus on how particulate matter air pollution impacts pulmonary function. We are also part of the LIBERATE clinical study, which is focused on patients who experience difficulty breathing and have been diagnosed with severe emphysema. We also have a longstanding interest in the effects of race/ethnicity, poverty and urbanization on nutrition and food allergies.

The Michael Klag Lab focuses on the epidemiology and prevention of kidney disease, cardiovascular disease and hypertension. Our research determined that the U.S. was experiencing an epidemic of end-stage kidney disease, pinpointed the incidence of kidney disease and published scholarship on risk factors for kidney disease such as race, diabetes and socioeconomic status. Our Precursors Study has shown that serum cholesterol measured at age 22 years is a predictor for midlife cardiovascular disease, a finding that has influenced policy about cholesterol screening in young adults. We also research health behaviors that lead to hypertension and study how differences in these behaviors affect urban and non-urban populations.

The TIC works with interdisciplinary teams to bring digital health products to life in clinical settings at Johns Hopkins Health System. TIC offers design, development, business, and project management partnership to solve clinical problems that span the range of medical specialties and practice settings. Through community-based events and programs, the TIC also works to train the next wave of digital health innovators and builds start-up teams with the tools to launch commercial products improving patient care at Johns Hopkins and across the industry.

The Sydney Dy Lab has conducted extensive research on quality of care, patient safety and decision-making, with a focus on patients with cancer and other serious and terminal diseases. Our team seeks to improve health systems and services to optimize the use of technology and medication, particularly in end-of-life health care policy. Our research approach includes primary and quantitative data collection, quality measurement improvement, systematic literature reviews and analysis of secondary database.
