The main focus of Dr. Gilotra's research is understanding the pathophysiology and outcomes in inflammatory cardiomyopathies including myocarditis and sarcoidosis, as well as improvement of heart failure patient care through noninvasive hemodynamic monitoring and studying novel strategies to reduce heart failure hospitalizations. Additional investigations involve clinical research in advanced heart failure therapies including heart transplantation and mechanical circulatory support. Dr. Gilotra is the site Principal Investigator for the NIH/NHLBI funded Heart Failure Network trials.

The Gregg Semenza Lab studies the molecular mechanisms of oxygen homeostasis. We have cloned and characterized hypoxia-inducible factor 1 (HIF-1), a basic helix-loop-helix transcription factor. Current research investigates the role of HIF-1 in the pathophysiology of cancer, cerebral and myocardial ischemia, and chronic lung disease, which are the most common causes of mortality in the U.S.

The Johns Hopkins Center for Epithelial Disorders focuses on research into the physiology and pathophysiology of epithelial cells (cells that line the cavities and interior surfaces of the body) of the gastrointestinal (GI) tract, liver, pancreas and kidney. Specifically, the center’s research seeks to: -Understand the mechanisms regulating the activity of transport proteins (including channels) of epithelial cells Characterize the mechanisms by which polarity of epithelial cells are maintained -Investigate the mechanisms controlling transcription of epithelial-specific genes Understand the pathophysiological basis of GI and renal diseases that involve the preceding three components -The center also provides a framework for training fellows in gastroenterology and hepatology to become independent investigators. The center is funded primarily through individual investigator-initiated extramural research grant support from the National Institutes of Health (NIH) as well as multi-investigator grants including RO1, PO1, UO1 and R24.

Dr. Cebotaru is the Director of Johns Hopkins Center for Gene Therapy research in Gastroenterology and research in the Cebotaru Lab studies cystic fibrosis transmembrane conductance regulator (CFTR) mutants as well as the pathophysiology of polycystic liver and kidney disease (PKD). They also investigate corrector molecules to get a better understanding of their mechanism of action. A major focus of her research is on developing more efficient gene therapy vectors with the ultimate goals of developing a gene therapy for cystic fibrosis and PKD.

The Hui lab performs basic, translational and clinical research on genetics and genomics of neurogastroenterological disorders. Ongoing projects include evaluation of sensory mechanisms in the pathophysiology of nausea using single-cell sequencing analysis of the vagal nodose ganglion cells and real world clinical data in order to understand mechanisms of this debilitating and poorly understood condition.

Lauren Jantzie, professor of pediatrics and vice chair of research for the Department of Pediatrics, received her Ph.D. in neurochemistry from the University of Alberta in 2008. In 2013 she completed her postdoctoral fellowship in the Department of Neurology at Boston Children's Hospital & Harvard Medical School and became faculty at the University of New Mexico. Dr. Jantzie then joined the faculty Departments of Pediatrics (Neonatal-Perinatal Medicine) and Neurology at Johns Hopkins University and the Kennedy Krieger Institute in January 2019.

The Jantzie lab investigates the pathophysiology of encephalopathy of prematurity, and pediatric brain injury common to infants and toddlers. Dr. Jantzie is dedicated to understanding disease processes in the developing brain as a means to identifying new therapeutic strategies and treatment targets for perinatal brain injury. Her lab studies neural substrates of cognition and executive function, inhibitory circuit formation, the role of an abnormal intrauterine environment on brain development, mechanisms of neurorepair and microglial activation and polarization.

Using a diverse array of clinically relevant techniques such as MRI, cognitive assessment, and biomarker discovery, combined with traditional molecular and cellular biology, the Jantzie lab is on the front lines of translational pediatric neuroscience.
