Wilmer Bioinformatics has been mainly focused on ocular informatics. Specifically, the group develops and applies bioinformatics approaches to study gene regulation and signaling networks, with particular but not exclusive attention to the mammalian retina. Understanding the molecular basis of tissue specific gene regulation and signaling will contribute to better prevention, diagnosis and treatment of retinal disease.

I am a primary care doctor and public health researcher committed to improving women’s health and health care across their lives and improving gender and racial equity.

I am an Associate Professor of Medicine in The Johns Hopkins University School of Medicine, Division of General Internal Medicine. My research focuses on identifying strategies to prevent and manage obesity and type 2 diabetes and cardiovascular disease, particularly among women at highest risk due to pregnancy complications. I conduct pragmatic and community-based randomized controlled trials to test high impact and scalable strategies to reduce excessive weight gain in pregnancy, reduce postpartum weight retention and cardiometabolic risk.

I hold several leadership positions, and I am the Director of Research at Johns Hopkins Community Physicians, the Co-Director of the Johns Hopkins Center for Women’s Health, Sex and Gender Research and a Core Faculty Member of the Welch Center for Prevention, Epidemiology and Clinical Research.

The Retinal Cell and Molecular Laboratory has three major areas of interest, each of which deals with some aspect of growth factor signaling and function in the retina and retinal pigmented epithelium (RPE): 1. Investigations aimed at gaining a better understanding of the pathogenesis of retinal and choroidal neovascularization and developing new ways to treat them. 2. Investigations aimed at understanding the molecular signals involved in retinal and RPE wound repair and scarring. The prototypical disease in this category is proliferative vitreoretinopathy and our laboratory is seeking to identify new treatments for it. 3. Investigations aimed at understanding why retinal degenerations occur and how they might be treated, with particular emphasis on neurotrophic factors.

The Outcomes After Critical Illness and Surgery Group is focused on understanding and improving patient outcomes after critical illness and surgery. Research projects include improving long-term outcomes research for acute respiratory distress syndrome/acute respiratory failure (ARDS/ARF) patients; examining the long-term outcomes for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) patients; and evaluating the effects of lower tidal volume ventilation and other aspects of critical illness and ICU care on the long-term physical and mental health outcomes of ALI/ARDS patients.

The mission of the Elisseeff Lab is to engineer technologies to repair lost tissues. We aim to bridge academic research and technology discovery to treat patients and address clinically relevant challenges related to tissue engineering. To accomplish this goal we are developing and enabling materials, studying biomaterial structure-function relationships and investigating mechanisms of tissue development to practically rebuild tissues. The general approach of tissue engineering is to place cells on a biomaterial scaffold that is designed to provide the appropriate signals to promote tissue development and ultimately restore normal tissue function in vivo. Understanding mechanisms of cellular interactions (both cell-cell and cell-material) and tissue development on scaffolds is critical to advancement of the field, particularly in applications employing stem cells. Translation of technologies to tissue-specific sites and diseased environments is key to better design, understanding, and ultimately efficacy of tissue repair strategies. We desire to translate clinically practical strategies, in the form of biomaterials/medical devices, to guide and enhance the body's natural capacity for repair. To accomplish the interdisciplinary challenge of regenerative medicine research, we maintain a synergistic balance of basic and applied/translational research.

Research in the Howard and Georgeanna Seegar Jones Reproductive Endocrinology Lab supports a broad interest in reproductive conditions, but has a particular focus on endometriosis, uterine fibroids, PMOS and genes causing infertility. PMOS and uterine fibroids are among the most prevalent conditions leading to infertility and diseases in women, but both remain poorly understood. Studying these areas may lead to the development of new treatments or preventative therapies.

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.

Basic science investigations in the Umapathi Lab focus on understanding how metabolic dysregulation drives heart failure and cardiomyopathy. The laboratory employs patient-derived induced pluripotent stem cell (iPSC) models, transgenic mouse systems, and advanced proteomics to define the molecular mechanisms underlying metabolic heart failure (MetHF), with particular emphasis on O-GlcNAcylation and cardiac energetics in heart failure. Additional research explores the mechanistic basis of contractile dysfunction/arrhythmias in inherited cardiomyopathies, particularly LMNA-related disease, integrating calcium signaling, mechanobiology, and electrophysiology to identify novel therapeutic targets for conduction abnormalities and ventricular arrhythmias.
