Alain Labrique Lab
The Alain Labrique Lab conducts research on infectious diseases and public health. Our team studies the various factors that lead to maternal and neonatal mortality, particularly in underserved populations in South Asia, using the tools of infectious disease epidemiology, molecular biology and biostatistics. We work to better understand factors such as the interface of micronutrient deficiency and maternal/infant mortality and the prevention of nosocomial infections through mechanistic or nutritional interventions. We also have a longstanding interest in technologies that may enable early detection of disease.
Amita Gupta Lab
The Amita Gupta Lab focuses on drug trials to prevent and treat HIV, tuberculosis (TB) and other co-morbidities in adults, including pregnant women and children who reside in low-income settings. We also conduct cohort studies assessing HIV, inflammation and nutrition in international settings; TB in pregnancy; and risk factors for TB in India (CTRIUMPH). We collaborate with several faculty in the Center for TB Research, Division of Infectious Diseases and the School of Public Health.
Research in the Anderson laboratory focuses on cellular signaling and ionic mechanisms that cause heart failure, arrhythmias and sudden cardiac death, major public health problems worldwide. Primary focus is on the multifunctional Ca2+ and calmodulin-dependent protein kinase II (CaMKII). The laboratory identified CaMKII as an important pro-arrhythmic and pro-cardiomyopathic signal, and its studies have provided proof of concept evidence motivating active efforts in biotech and the pharmaceutical industry to develop therapeutic CaMKII inhibitory drugs to treat heart failure and arrhythmias.
Under physiological conditions, CaMKII is important for excitation-contraction coupling and fight or flight increases in heart rate. However, myocardial CaMKII is excessively activated during disease conditions where it contributes to loss of intracellular Ca2+ homeostasis, membrane hyperexcitability, premature cell death, and hypertrophic and inflammatory transcription. These downstream targets a...ppear to contribute coordinately and decisively to heart failure and arrhythmias. Recently, researchers developed evidence that CaMKII also participates in asthma.
Efforts at the laboratory, funded by grants from the National Institutes of Health, are highly collaborative and involve undergraduate assistants, graduate students, postdoctoral fellows and faculty. Key areas of focus are:
• Ion channel biology and arrhythmias
• Cardiac pacemaker physiology and disease
• Molecular physiology of CaMKII
• Myocardial and mitochondrial metabolism
• CaMKII and reactive oxygen species in asthma

Andrew Lane Lab
The Lane laboratory is focused on understanding molecular mechanisms underlying chronic rhinosinusitis and particularly the pathogenesis of nasal polyps. Diverse techniques in molecular biology, immunology, physiology, and engineering are utilized to study epithelial cell innate immunity, olfactory loss, the sinus microbiome, and drug delivery to the nose and sinus cavities. Ongoing work explores how epithelial cells participate in the immune response and contribute to chronic sinonasal inflammation. The lab creates and employs transgenic mouse models of chronic sinusitis to support research in this area. Collaborations are in place with the School of Public Health to explore mechanisms of anti-viral immunity in influenza and rhinovirus, and with the University of Maryland to characterize the bacterial microbiome of the nose and sinuses in health and disease.

Casey Overby Lab
Research in the Casey Overby Lab focuses on the intersection of public health genomics and biomedical informatics. We’re currently developing applications to support the translation of genomic research to clinical and population-based health care settings. We’re also working to develop knowledge-based ways to use big data — including electronic health records — to improve population health.
We are interested in how immune responses occur in the cervix. The focus of our translational research is on developing immune therapies for disease caused by human papillomavirus (HPV). HPV infection causes more cancers than any other virus in the world. Cervical cancer is the most common cancer caused by HPV, and although we have known how to screen for it for over half a century, it remains the second most common cause of cancer death in women. Although the preventive vaccines are a public health milestone, they prevent HPV infections, but are not designed to make immune responses to treat HPV. We are testing different strategies to make immune responses that could treat HPV disease. Our dedicated researchers are working to extend the techniques used in HPV vaccine development to the creation of vaccines targeting other cancers with defined tumor antigens.

The Ramanathan Lab
Chronic rhinosinusitis (CRS) is a leading cause of morbidity globally and is the single most common self-reported chronic health condition and accounts for billions of dollars in health care costs and lost work days annually. Exposure to air pollutants is thought to be a critical modifier of CRS susceptibility. Despite marked reductions in air pollution levels in the United States, the fine particulate component of air pollution (PM2.5) and ultrafine pollutants secondary to traffic continue to remain a recalcitrant issue globally and in the United States. The Ramanathan Lab focuses on studying the role of air pollution (PM2.5) in CRS. In collaboration with scientists at the Bloomberg School of Public Health, we have utilized a state of the art air pollution exposure system to develop a novel mouse model of air pollution induced rhinosinusitis that mimics many of the features of CRS in humans. Our lab uses transgenic mouse models and novel immunologic/genomic techniques to study the mec...hanisms by which PM2.5 causes eosinophilic inflammation and sinonasal epithelial barrier dysfunction. We are also interested in the role of the antioxidant transcription factor, Nrf2, which has shown to stabilize the epithelial barrier and reduce eosinophilia in PM induced rhinosinusitis as a potential therapeutic target. view more
