Research in the Michael A. Rosen Lab primarily focuses on patient safety and simulation-based health care training and technology. Recent work provided examples of how human factors experts can collaborate with health care professionals and simulationists (experts in the design and implementation of simulation) to use contemporary simulation to improve health care delivery. Another recent study examined the anesthesia practice at two tertiary care hospitals in Sierra Leone, West Africa, where anesthesia is associated with high mortality rates. We identified gaps in the application of internationally recommended anesthesia practices at both hospitals, likely caused by lack of available resources.

The Hoffmann Lab is focused on reducing TB and HIV morbidity and mortality in the low and middle income settings through behavioral and implementation science approaches. Work has focused on understanding individual-level behavior towards linkage to care and continued care engagement for HIV and TB and using this knowledge to develop approaches to increase HIV testing, linkage to care, HIV viral load suppression, and retention in care. Other work has focused on health system strategies to improve service delivery and improve adherence to best practice to guidelines-based care. The group's research includes work on the general population, corrections inmates and ex-inmates, men at risk for HIV, and recently hospitalized individuals. Most of the research has been in South Africa and elsewhere in sub-Saharan Africa.

Research in the Richard Chaisson Lab primarily examines tuberculosis and HIV infection, with specific focus on global epidemiology, clinical trials, diagnostics and public health interventions. Our recent research has involved evaluating a molecular diagnostic test for tuberculosis in HIV patients; observing TB responses during treatment of pulmonary tuberculosis; and examining antiretroviral therapy adherence, virologic and immunologic outcomes in adolescents compared with adults in Southern Africa.

The Post Lab is involved in the Multi-Ethnic Study of Atherosclerosis (MESA), a collaborative study of the characteristics of subclinical cardiovascular disease (that is, disease detected non-invasively before it has produced clinical signs and symptoms) and the risk factors that predict progression to clinically overt cardiovascular disease or progression of the subclinical disease. As MESA researchers, we study a diverse, population-based sample of 6,814 asymptomatic men and women aged 45-84. Approximately 38 percent of the recruited participants are white, 28 percent African-American, 22 percent Hispanic, and 12 percent Asian, predominantly of Chinese descent. Participants were recruited from six field centers across the United States, including Johns Hopkins University. Each participant received an extensive physical exam to determine a number of conditions, including coronary calcification, ventricular mass and function, flow-mediated endothelial vasodilation, standard coronary risk factors, sociodemographic factors, lifestyle factors, and psychosocial factors. Selected repetition of subclinical disease measures and risk factors at follow-up visits have allowed study of the progression of disease. Participants are being followed for identification and characterization of cardiovascular disease events, including acute myocardial infarction and other forms of coronary heart disease (CHD), stroke, and congestive heart failure; for cardiovascular disease interventions; and for mortality. Wendy S. Post, MD, MS, is an associate faculty, Welch Center for Prevention, Epidemiology, and Clinical Research, Johns Hopkins University, and a professor of medicine.

Research in the Jonathan Golub Lab focuses primarily on the epidemiology of tuberculosis (TB), specifically in patients infected with HIV. We work with the CDC to explore potential delays in TB diagnoses as well as the risk factors that contribute to death from TB in the United States. Our research also includes ongoing studies of HIV and TB patients in Brazil and South Africa.

Research in the J. Hunter Young Lab focuses on the genetic epidemiology and physiology of cardiovascular disease and its risk factors, especially hypertension, diabetes and obesity. Current activities include an observational study of hypertension among African Americans; a genetic epidemiology study of worldwide cardiovascular disease susceptibility patterns; and several population-based observational studies of cardiovascular and renal disease. A recent focus group study found that changes in housing and city policies might lead to improved environmental health conditions for public housing residents.

Research in the Hansoti Lab centers on the intersection of public health interventions for vulnerable populations and emergency department care. The lab employs implementation science methodologies, with a particular emphasis on mixed-methods research to design, develop, and evaluate innovative, evidence-based strategies that support socially vulnerable patients.

In South Africa, the team is pioneering strategies to enhance HIV prevention and intervention delivery within emergency departments, focusing on improving HIV service delivery for patients missed within the health system and delivering preventative care strategies to patients at high risk of HIV acquisition. These efforts are concentrated at Tygerberg Hospital and Gugulethu Clinic, in partnership with the Desmond Tutu HIV Foundation.

Domestically, the lab conducts research on opioid use disorder (OUD), specifically addressing post-discharge health system challenges related to linkage to care and retention for patients prescribed medications for opioid use disorder (MOUD). This includes addressing social determinants of health to strengthen HIV services for patients who present to the ED.

Additionally, Dr. Hansoti has a dedicated focus on surveillance strategies for high-consequence pathogens in emergency departments. She serves as the Principal Investigator for the Clinical Characterization Protocol for Severe Emerging Infections (CCPSEI) and manages cohorts for both COVID-19 and mpox, in collaboration with experts in public health, epidemiology, and infectious diseases from the Johns Hopkins School of Public Health.

The Lisa Cooper Lab is dedicated to researching patient-centered interventions for improving health outcomes and overcoming racial and ethnic disparities in health care. Our primary focus is on the factors of physician communication skills and cultural competence training, patient shared decision-making and self-management skills training. Recently, we have explored patient-centered depression care for African Americans, tactics for improving patient-physician communication about management of hypertension, and reducing ethnic and social disparities in health. In addition, we are currently researching racial disparities in cardiovascular health outcomes for patients living in Baltimore.
