Cardiology Bioengineering Laboratory
Lab WebsiteThe Cardiology Bioengineering Laboratory, located in the Johns Hopkins Hospital, focuses on the... applications of advanced imaging techniques for arrhythmia management. The primary limitation of current fluoroscopy-guided techniques for ablation of cardiac arrhythmia is the inability to visualize soft tissues and 3-dimensional anatomic relationships.
Research Areas: magnetic resonance imaging, CPR models, cardiac mechanics, MRI-guided therapy, ischemic tachycardia, arrhythmia, cardiology, sudden cardiac death, cardiopulmonary resuscitation, computational modeling
Implementation of alternative advanced modalities has the potential to improve complex ablation procedures by guiding catheter placement, visualizing abnormal scar tissue, reducing procedural time devoted to mapping, and eliminating patient and operator exposure to radiation.
Active projects include
• Physiological differences between isolated hearts in ventricular fibrillation and pulseless electrical activity
• Successful ablation sites in ischemic ventricular tachycardia in a porcine model and the correlation to magnetic resonance imaging (MRI)
• MRI-guided radiofrequency ablation of canine atrial fibrillation, and diagnosis and intervention for arrhythmias
• Physiological and metabolic effects of interruptions in chest compressions during cardiopulmonary resuscitation
Henry Halperin, MD, is co-director of the Johns Hopkins Imaging Institute of Excellence and a
professor of medicine, radiology and biomedical engineering. Menekhem M. Zviman, PhD is the laboratory manager.

Hanan Aboumatar Lab
Lab WebsiteResearch in the Hanan Aboumatar Lab focuses on advancing patient-centered outcomes through impr...oved 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. view more

Hsin-Chieh Yeh Lab
Lab WebsiteWork in the Hsin-Chieh Yeh Lab focuses on clinical trials and cohort studies of diabetes, obesi...ty and behavioral intervention, cancer and hypertension. Recent investigations have focused on novel risk factors and complications related to obesity and type 2 diabetes, particularly lung function, smoking and cancer. We recently co-led a randomized clinical trial of tailored dietary advice for consumption of dietary supplements to lower blood pressure and improve cardiovascular disease risk factors in hypertensive urban African Americans. view more

Jeanne Clark Lab: GIM Research
Lab WebsiteResearch in the Jeanne Clark Lab covers a wide range of fields, employing various research tech...niques, methods and procedures to generate and disseminate the knowledge required to prevent disease and its consequences. Our most recent research program, Look AHEAD, focuses on the health of overweight volunteers with type 2 diabetes. We are examining the long-term effects of an intensive lifestyle intervention program designed to achieve and maintain weight loss by decreased caloric intake and increased physical activity. view more

Kristin Riekert Lab
Work in the Kristin Riekert Lab focuses on methods for improving health care quality and delive...ry, particularly among underserved and disadvantaged populations. Our research covers a range of important topics, including health beliefs, treatment adherence, doctor-patient communication, self-management interventions, mobile health initiatives, health disparities and patient-reported outcome methodology. We also work with the National Institutes of Health on multiple intervention trials focused on improving adherence and health outcomes in asthma, chronic kidney disease, cystic fibrosis (CF), sickle cell disease and secondhand smoke reduction. view more
Research Areas: health care quality, treatment adherence, cystic fibrosis, patient-provider relationships, chronic illnesses, health disparities -
Larry Chang Lab
Research in the Larry Chang Lab focuses on innovative, multidisciplinary and pragmatic approach...es to impacting the HIV/AIDS pandemic. Our research investigates ways to improve HIV/AIDS care in low- and middle-income settings through strategies that include quantitative methods, qualitative methods, community-based trial designs, and behavioral science and economic evaluations. In addition, we research mobile technologies for health (mHealth) strategies for improving global public health and clinical care, including novel applications for intimate-partner violence intervention, dengue surveillance, and HIV care, surveillance and prevention. view more

Sean Berenholtz Lab
Lab WebsiteWork in the Sean Berenholtz Lab focuses on patient safety, ICU care, quality health care and ev...idence-based medicine. Two notable and successful projects include the National On The Cusp: Stop BSI project, which was implemented in 47 states with the goal of eliminating bloodstream infections, and the Agency for Healthcare Research and Quality (AHRQ)-funded Keystone ICU project, which improved communication and teamwork and reduced hospital-acquired infections in more than 100 ICUs in Michigan. One recent study focused on ventilator-associated pneumonia (VAP), one of the most common type of health care-associated infections in the ICU. Existing VAP prevention intervention bundles vary widely on the interventions, but our research team described a structured approach for developing a new VAP prevention bundle. view more

Srinivasan Yegnasubramanian Lab
Lab WebsiteDr. Yegnasubramanian directs a Laboratory of Cancer Molecular Genetics and Epigenetics at the S...idney Kimmel Comprehensive Cancer Center (SKCCC), and is also the Director of the SKCCC Next Generation Sequencing Center.
Research Areas: cancer therapies, biomarkers, genetics, cancer, epigenetics
Our lab research is focused on understanding the complex interplay between genetic and epigenetic alterations in carcinogenesis and disease progression, and to exploit this understanding in developing novel biomarkers for diagnosis and risk stratification as well as in identifying targets for therapeutic intervention. view more -
The Vernon Lab for Translational Mitochondrial Medicine
Lab WebsiteDr. Vernon’s Laboratory at the Department of Genetic Medicine develops and studies cellular mod...els of mitochondrial disorders to understand their biological basis and to find new targets for therapeutic intervention. view more
Research Areas: Cellular Models of Disease, Mitochondrial disorders, Barth syndrome, Organic Acidemias -
Translational Neurobiology Laboratory
Lab WebsiteThe goals of the Translational neurobiology Laboratory are to understand the pathogenesis and c...ell death pathways in neurodegenerative disorders to reveal potential therapeutic targets for pharmaceutical intervention; to investigate endogenous survival pathways and try to induce these pathways to restore full function or replace lost neurons; and to identify biomarkers to mark disease function or replace lost neurons; and to identify biomarkers to mark disease progression and evaluate therapeutics. Our research projects focus on models of Huntington's disease and Parkinson's disease. We use a combination of cell biology and transgenic animal models of these diseases. view more
