Ari Cedars Laboratory
Ari Cedars, M.D., and his team have three primary research goals. First, the Cedars Lab is interested in patient-centered outcomes in congenital heart disease, which they investigate using a digital tracking system to record participants’ symptoms and quality of life. Second, the Cedars Lab investigates outcomes with mechanical circulatory support and transplant in congenital heart disease, with a focus on those with end-stage heart disease and a Fontan circulation. Third, the Cedars Lab is interested in the biological mechanisms underlying circulatory deterioration and end-organ dysfunction in patients with a Fontan circulation. -
Balagopal Lab - Viral Hepatitis and Translational Virology
The Balagopal Lab has adapted high-resolution tools to study viruses in situ. Specifically, we were the first to quantify hepatitis C virus (HCV) infection in single hepatocytes by developing single-cell laser capture microdissection (scLCM) and integrating this tool with highly sensitive quantitative real-time PCR. We reported that HCV infects a minority of hepatocytes that are found in geospatial clusters. More recently, we (PIs Balagopal and Thio) integrated scLCM with droplet digital PCR (ddPCR) to reveal the first observations of hepatitis B virus (HBV) infection at single cell resolution in the liver. We found that HBV infects nearly all hepatocytes prior to antiviral therapy. However, during antiviral therapy, HBV infection is diminished while viral transcription is markedly attenuated. Our lab has also focused on HIV-1 infection and immune activation for over a decade. Most recently, we have studied type 1 interferon responses to HIV-1 using RNA sequencing (RNAseq). Using this technology, we identified novel interferon-stimulated genes (ISGs) that are associated with HIV-1 restriction in vivo. -
Alex Kolodkin Laboratory
Research in the Alex Kolodkin Laboratory is focused on understanding how neuronal connectivity is established during development. Our work investigates the function of extrinsic guidance cues and their receptors on axonal guidance, dendritic morphology and synapse formation and function. We have investigated how neural circuits are formed and maintained through the action of guidance cues that include semaphorin proteins, their classical plexin and neuropilin receptors, and also novel receptors. We employ a cross-phylogenetic approach, using both invertebrate and vertebrate model systems, to understand how guidance cues regulate neuronal pathfinding, morphology and synaptogenesis. We also seek to understand how these signals are transduced to cytosolic effectors. Though broad in scope, our interrogation of the roles played by semaphorin guidance cues provides insight into the regulation of neural circuit assembly and function. Our current work includes a relatively new interest in understanding the origins of laminar organization in the central nervous system. -
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. -
Alan Baer Lab
Research in the Alan Baer Lab focuses on Sjogren's syndrome. Previously, we conducted the Sjogren's International Registry (SICCA), enrolling 300 patients and creating a valuable source of clinical data and biospecimens for research we're conducting with colleagues at Johns Hopkins and the University of California-San Francisco. Currently, we're conducting a longitudinal observational study of patients with Sjogren's syndrome. We're also collaborating with Dr. Ben Larman in the Department of Pathology, using phage immuno-precipation sequencing to work on a characterization of the complete autoantibody repertoire in Sjogren's syndrome patients. -
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. Active projects: 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. For more information please visit Cport.org. -
Alan Scott Lab
Research in the Alan Scott Lab involves several important areas of genomics. Our team collaborates on a study to investigate the exon and genome sequence variants that determine phenotype, with a specific focus on the genetic bases of cleft lip and palate. We are also involved in assessing and improving genomic technologies to provide next-generation sequencing and analysis of sequence data to the clinical environment. In addition, we have a longstanding interest in the problem of gene annotation and the evolutionary genomics of vertebrates, especially endangered species. -
Alzheimer's Disease Research Center
The goal of the Johns Hopkins Alzheimer's Disease Research Center (ADRC) is to accelerate the discovery of new treatments that are directed at the basic mechanisms of disease, and to hasten the time when effective treatments for AD and related disorders become a reality. We have a strong commitment to basic research regarding the underlying mechanisms of Alzheimer's Disease and related disorders, and how this may translate into effective treatment. We perform clinical research seeking to identify medications to delay or treat the symptoms of dementia. We also provided many educational programs for family members and professionals. -
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.Principal Investigator

Amit Pahwa Lab
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.
