Stephen Sozio Lab
Dr. Sozio’s research focuses on 1) Clinical research related to chronic kidney disease and end stage renal disease, and 2) Educational research in undergraduate and graduate medical education.
The Sozio lab pursues work related to stroke, cognitive impairment, manifestations of kidney disease, and systematic reviews on clinical topics, and collaborates on multiple projects with other key investigators. In particular, Dr. Sozio has been an active investigator in the Choices for Healthy Outcomes in Caring for ESRD (CHOICE) Study, Predictors of Arrhythmic and Cardiovascular Risk in End Stage Renal Disease (PACE) Study, Chronic Renal Insufficiency Cohort (CRIC) Study, and work funded through the Agency for Healthcare Research and Quality (AHRQ) and Johns Hopkins Evidence-Based Practice Center. In addition, the Sozio lab performs studies at the UME and GME levels, investing in understanding learners’ mentorship, research, and transitional experiences.
Steven Beaudry Lab
Research in the Steven Beaudry Lab aims to better understand the cellular and molecular mechanisms behind cardiovascular disease in pregnancy. Our goal is to develop more effective treatments and improve patient outcomes.
Systems Biology Laboratory
The Systems Biology Lab applies methods of multiscale modeling to problems of cancer and cardiovascular disease, and examines the systems biology of angiogenesis, breast cancer and peripheral artery disease (PAD).
Using coordinated computational and experimental approaches, the lab studies the mechanisms of breast cancer tumor growth and metastasis to find ways to inhibit those processes.
We use bioinformatics to discover novel agents that affect angiogenesis and perform in vitro and in vivo experiments to test these predictions. In addition we study protein networks that determine processes of angiogenesis, arteriogenesis and inflammation in PAD. The lab also investigates drug repurposing for potential applications as stimulators of therapeutic angiogenesis, examines signal transduction pathways and builds 3D models of angiogenesis.
The lab has discovered over a hundred novel anti-angiogenic peptides, and has undertaken in vitro and in vivo studies testing their activity unde...r different conditions. We have investigated structure-activity relationship (SAR) doing point mutations and amino acid substitutions and constructed biomimetic peptides derived from their endogenous progenitors. They have demonstrated the efficacy of selected peptides in mouse models of breast, lung and brain cancers, and in age-related macular degeneration.
The Arking Lab
The Arking Lab studies the genomics of complex human disease, with the primary goal of identifying and characterizing genetics variants that modify risk for human disease. The group has pioneered the use of genome-wide association studies (GWAS), which allow for an unbiased screen of virtually all common genetic variants in the genome. The lab is currently developing improved GWAS methodology, as well as exploring the integration of additional genome level data (RNA expression, DNA methylation, protein expression) to improve the power to identify specific genetic influences of disease.
The Arking Lab is actively involved in researching:
• autism, a childhood neuropsychiatric disorder
• cardiovascular genomics, with a focus on electrophysiology and sudden cardiac death (SCD)
• electrophysiology is the study of the flow of ions in biological tissues

The Atlantic Cardiovascular Patient Outcomes Research Team - Atlantic C-PORT
Our research is centered on the safety, efficacy and outcomes of PCI performed at hospitals without on-site cardiac surgery.
C-PORT Randomized Studies and Registries; New Jersey Angioplasty Demonstration Project; InCar-decision support tools for performance of PCI at hospitals without on-site cardiac surgery.

The Barouch Lab
The Barouch Lab is focused on defining the peripheral cardiovascular effects of the adipocytokine leptin, which is a key to the understanding of obesity-related cardiovascular disease. Interestingly, many of the hormonal abnormalities seen in obesity are mimicked in heart failure. The research program will enhance the understanding of metabolic signaling in the heart, including the effects of leptin, exercise, sex hormones, and downstream signaling pathways on metabolism and cardiovascular function.
The lab also is working to determine the precise role of the “metabolic” beta-3 adrenergic receptor (ß3AR) in the heart and define the extent of its protective effect in obesity and in heart failure, including its role in maintaining nitric oxide synthase (NOS) coupling. Ultimately, this work will enable the exploration of a possible therapeutic role of ß3AR agonists and re-coupling of NOS in preventing adverse ventricular remodeling in obesity and in heart failure.
Lili Barouch, MD,... is an associate professor of medicine in the Division of Cardiology and a member of the Advanced Heart Failure and Cardiac Transplantation group at the Johns Hopkins University School of Medicine. view more
The Halushka laboratory is interested in the overarching question of expression localization in tissues. To address this, the laboratory has set out upon several avenues of discovery in the areas of microRNA expression, proteomics and tissue gene expression. Many of these queries relate to the cardiovascular field as Dr. Halushka is a cardiovascular pathologist. Come learn about the science being done in the laboratory.
Work in the Wei Dong Gao Lab primarily focuses on heart failure and defining molecular and cellular mechanisms of contractile dysfunction. We use molecular biology and proteomic techniques to investigate the changes that myofilament proteins undergo during heart failure and under drug therapy. We're working to determine the molecular nature of nitroxyl (HNO) modification of tropomyosin.
Zack Wang Lab
The Wang lab focuses on the signals that direct the differentiation of pluripotent stem cells, such as induced-pluripotent stem (iPS) cells, into hematopoietic and cardiovascular cells. Pluripotent stem cells hold great potential for regenerative medicine. Defining the molecular links between differentiation outcomes will provide important information for designing rational methods of stem cell manipulation.
