Biomaterials, Cancer Biology, Cardiovascular Biology, Cell Biology, Translational Medicine

The Polacheck Lab develops microfluidic and organ-on-chip technology for disease modeling and regenerative medicine. Our efforts are organized around three primary research thrusts: 1) Developing humanized microphysiological models for inherited and genetic disorders; 2) Defining the role of biofluid mechanics and hemodynamics on the cellular microenvironment; 3) Understanding the role of cell-cell adhesion in the generation and propagation of cellular forces during morphogenesis. We further work to translate the technology and techniques developed in our lab into tissue engineered therapies for organ replacement and regenerative medicine.

My group develops and deploys computational tools to predict physiological function and dysfunction. We are interested in a range of applications in medicine and biology, but our primary focus is the cardiovascular system. My group is actively developing fluid-structure interaction (FSI) models of the heart, arteries, and veins, and of cardiovascular medical devices, including bioprosthetic heart valves, ventricular assist devices, and inferior vena cava filters. We are also validating these models using in vitro and in vivo approaches. We also model cardiac electrophysiology and electro-mechanical coupling, with a focus on atrial fibrillation (AF), and aim to develop mechanistically detailed descriptions of thrombosis in AF. This work is carried out in collaboration with clinicians, engineers, computer and computational scientists, and mathematical scientists in academia, industry, and regulatory agencies.

The main goal of the Nagarajan lab research program focuses on how the innate branch of the immune system regulates adaptive immunity, as it relates to the pathogenesis of autoimmune disease such as lupus or rheumatoid arthritis (RA)-induced cardiovascular disease.   IgG-Fcgamma receptor (FcgR)-mediated signaling is critical for mediating host defense against infectious disease, but they also mediate disease pathology in autoimmunity and atherosclerosis. Specifically, we are studying the role of IgG-Fcgamma receptor (FcgR) signaling network in innate immune cells activation that contributes to autoantibody production and T cell subset activation associated with autoimmune, and cardiovascular diseases.  We are using a repertoire of relevant knockout mouse and humanized FcgR mouse models to address the questions of how FcgR-mediated signaling promotes autoimmune disease-induced atherosclerosis. As a translational component, we are collaborating with rheumatologists and cardiologists to analyze changes in innate and T cell subsets in patients with lupus or RA, who has premature atherosclerosis.

The Shaikh lab aims to understand how differing dietary fatty acids regulate outcomes associated with immunity and metabolism in the context of obesity, type 2 diabetes, and cardiovascular diseases. The lab conducts studies at the human level and in mouse models.  We are currently focused on the mechanisms by which omega-3 fatty acids improve chronic inflammation and humoral immunity upon viral infection in obesity. We are also elucidating how select fatty acids disrupt the biophysical organization of the inner mitochondrial membrane of differing cell types and thereby respiratory activity.

My research focus pertains to vascular remodeling as it relates to the pathogenesis and progression of thoracic aortic aneurysms. Using murine and porcine models, as well as human aneurysm tissue samples, we study proteinase and signaling biology with a view towards defining novel modalities targets for diagnosis, tracking, risk stratification and non-surgical treatment of this devastating disease.

Congenital heart diseases are one of the most common birth defects in humans, and these arise from developmental defects during embryogenesis.  Many of these diseases have a genetic component, but they might also be affected by environmental factors such as mechanical forces. The Liu Lab combines genetics, molecular and cell biology to study cardiac development and function, focusing on the molecular mechanisms that link mechanical forces and genetic factors to the morphogenesis of the heart.  Our studies using zebrafish as a model system serve as the basic foundation to address the key questions in cardiac development and function, and could provide novel therapeutic interventions for cardiac diseases.

Toxicology

RESEARCH INTEREST
Cardiovascular Biology, Cell Signaling, Physiology, Toxicology, Translational Medicine

Research in my laboratory focuses on the cardiovascular effects of air pollution and other environmental pollutants in human, animal, and in vitro models, as well as the dietary interventional strategies to mitigate the adverse health effects of air pollution exposure. We are currently conducting two clinical studies to investigate the cardiopulmonary effects of air pollution exposure, and to determine whether dietary omega-3 fatty acids can mitigate the air pollution-induced health effects in human volunteers. These studies provide good training opportunities for students who are interested in training in clinical and translational toxicology research.

Gordon-Larsen’s work integrates biology, behavior, and environment to understand, prevent and treat obesity, cardiovascular and cardiometabolic diseases. She works with biomarker, microbiome, metabolome, genetic, weight, diet, and environment data using multilevel modeling and pathway-based analyses. She works with several longitudinal cohorts that span more than 30 years. Most of her work uses data from the US and China. Her research teams include a wide variety of scientists working in areas such as genetics, medicine, bioinformatics, biostatistics, microbiology, nutrition, and epidemiology.

Air pollution exposure is associated with increased hospital visits and mortality, and is a major area of research for the United States Environmental Protection Agency.  The primary research interest of my laboratory is the examination of the effects and mechanisms of air pollutants in the environment on normal cardiopulmonary function (cardiac toxicology), particularly in models of cardiovascular disease, using state-of-the-art targeted and high throughput methods. Research findings are often used to inform environmental public health and contribute to the refinement of the US EPA’s National Ambient Air Quality Standards for specific air pollutants set to limit their health impact.

The work focuses on how air pollutants affect human health, the role of genetics and epigenetic factors in determining susceptibility and clinical/dietary strategies to mitigate these effects. There is a strong emphasis on translational research projects using a multi-disciplinary approach. Thus, by using human in vivo models (such as clinical studies) we validate in vitro, epidemiology, and animal findings.
