The Amit Pahwa Lab conducts research on a variety of topics within internal medicine. Our most recent studies have explored misanalysis of urinalysis results, urinary fractional excretion indices in the evaluation of acute kidney injury and nocturnal enuresis as a risk factor for falls in older women. We also investigate cancer diagnostics and treatments. In this area, our recent research has included studying cutaneous shave biopsies for diagnosing primary colonic adenocarcinoma as well as growth inhibition and apoptosis in human brain tumor cell lines using selenium.
Research in the David Sullivan Lab focuses on malaria, including its diagnosis, treatment, molecular biology as it relates to iron, and pathology as it relates to severe anemia. We test and develop new malaria diagnostics — from real-time polymerase chain reaction (PCR) to novel urine and saliva detection platforms. This includes the adaptation of immuno-PCR (antibody coupled to DNA for PCR detection) to malaria and a lead blood stage drug that contains a quinine derivative used to treat malaria in the 1930s.
The Elizabeth Selvin Lab examines the intersection of epidemiology, clinical policy and public health policy. One of our key goals is to use the findings of epidemiologic research to inform the screening, diagnosis and treatment of diabetes, cardiovascular disease and kidney disease. Much of our work looks at biomarkers and diagnostics related to diabetes and diabetes complications. Our findings — linking hemoglobin A1c (HbA1c) to diabetic complications and identifying the role of A1c in diabetes diagnosis — have influenced clinical practice guidelines.
The Karakousis Lab is primarily focused on understanding the molecular basis of Mycobacterium tuberculosis persistence and antibiotic tolerance. A systems biology-based approach, including the use of several novel in vitro and animal models, in combination with transcriptional, proteomic, genetic, imaging, and computational techniques, is being used to identify host cytokine networks responsible for immunological control of M. tuberculosis growth, as well as M. tuberculosis regulatory and metabolic pathways required for bacillary growth restriction and reactivation. In particular, we are actively investigating the regulatory cascade involved in the mycobacterial stringent response. Another major focus of the lab is the development of host-directed therapies for TB, with the goal of shortening treatment and improving long-term lung function. Additional research interests include the development of novel molecular assays for the rapid diagnosis of latent TB infection and active TB diseas...e, and for the detection of drug resistance.view more
The Laboratory for Integrated NanoDiagnostics (LIND) is developing innovative technologies for accurate, fast, compact, portable, manufacturable, low-cost diagnostics for a wide variety of applications. Our current focus is a large-scale collaboration with imec, a leading microelectronics company in Leuven, Belgium, where our silicon is designed and manufactured. With major funding from miDiagnostics we are inventing solutions that are opening new avenues.
Work in the Maunank Shah Lab focuses on infectious disease modeling and health economics, and seeks to investigate new strategies for diagnosing HIV and tuberculosis (TB) in areas with limited resources, both domestically and abroad. Our primary focus is TB diagnostics, with studies examining the diagnostic test accuracy, cost-effectiveness and programmatic impact of emerging diagnostics. We have developed mobile health initiatives to incorporate video-based therapy for TB treatment, and we have a longstanding interest in interventions that help to reduce or prevent HIV transmission.
The Maura McGuire Lab focuses on the improvement of quality and safety in ambulatory medicine through care management, point-of-care laboratory testing, and electronic health records and care delivery optimization. We also study the use of assessment and technology to augment learning in health care professionals and primary care physicians.
The Natasha Chida Lab investigates methods for using education and curriculum development to improve patient outcomes worldwide, primarily by optimizing education of physicians-in-training. Most recently, our team has worked to develop and evaluate an assessment tool for evaluating internal medicine residents’ understanding of tuberculosis diagnostics. Previous research includes a retrospective cohort study on the high proportion of extrapulmonary TB in a low-prevalence setting as well as an analysis of ways to define clinical excellence in adult infectious disease practice.
Research in the Richard Chaisson Lab primarily examines tuberculosis and HIV infection, with specific focus on global epidemiology, clinical trials, diagnostics and public health interventions. Our recent research has involved evaluating a molecular diagnostic test for tuberculosis in HIV patients; observing TB responses during treatment of pulmonary tuberculosis; and examining antiretroviral therapy adherence, virologic and immunologic outcomes in adolescents compared with adults in Southern Africa.
The key research interests in the Robert Bollinger Lab include identifying biological and behavioral risk factors for HIV transmission as well as characterizing the clinical progression and treatment of HIV and related infectious diseases. We also have a long-standing interest in optimizing health care capacity and delivery in settings with limited resources. Our work includes implementing science research projects to explore the effectiveness of initiatives such as task-shifting, clinical education, distance learning and mobile health programs as a way to improve health care in these locations.
The mission of the Transplant and Oncology Infectious Diseases (TOID) Center is to expand institutional expertise in clinical and academic activities focused on infectious complications in transplant (solid organ and stem cell) and oncology patients at Johns Hopkins medical institutions. Key efforts include developing standardized algorithms for the prevention and treatment of infections in these vulnerable patients and to establish an expanded infrastructure to facilitate clinical and translational studies at TOID. Current research projects focus on diagnostics for invasive fungal infections and specialized studies of the pathogenesis of candidiasis and aspergillosis.
The William Bishai Laboratory studies the molecular pathogenesis of tuberculosis. The overall goal of our laboratory is to better understand tuberculosis pathogenesis and then to employ this understanding toward improved drugs, vaccines and diagnostics.
Since Mycobacterium tuberculosis senses and adapts to a wide array of conditions during the disease process, it is clear that the regulation of expression of virulence factors plays an important role in pathogenesis. As a result, a theme of our research is to assess mycobacterial genes important in gene regulation.
We are also interested in cell division in mycobacteria and the pathogenesis of caseation and cavitation.
Investigators in the Yukari Manabe Lab evaluate the accuracy of rapid, point-of-care diagnostics for HIV, tuberculosis and related infectious diseases in resource-limited settings particularly sub-Saharan Africa and examine the impact of diagnostic interventions on disease detection and patient outcomes. The team also conducts operational and translational research in tuberculosis and HIV co-infection.
