Alison Moliterno Lab
The Alison Moliterno Lab studies the molecular pathogenesis of myeloproliferative disorders (MPDs), including polycythemia vera, essential thrombocytosis and idiopathic myelofibrosis. Our research is focused on the genetic and epigenetic lesions associated with MPDs, with the goal of improving diagnosis and treatment for these disorders.
We specialize in unconventional, multi-disciplinary approaches to studying the heart at the intersection of applied mathematics, physics and computer science. We focus on theory development that leads to new technology and value delivery to the society. Currently we have three research programs:
1. Precision Medicine
To develop a quantitative approach to personalized risk assessment for stroke and dementia based on patent-specific heart anatomy, function and blood flow.
Disciplines: Cardiac Hemodynamics; Medical Imaging Physics; Continuum Mechanics; Computational Fluid Dynamics
2. Information Theory
To quantify and perturb cardiac fibrillation that emerges as a macro-scale behavior of the heart from micro-scale behaviors of inter-dependent components.
Disciplines: Cardiac Electrophysiology; Spiral Wave; Information Theory; Complex Networks
3. Artificial Intelligence
To develop artificial intelligence algorithms to predict the future risk of heart attack, stroke and sudden... death, and to assist surgical interventions to prevent these outcomes.
Disciplines: Medical Imaging Physics; Artificial Intelligence; Robotically Assisted Interventions
Dr. Braunstein's research focuses on inherited predisposition to hematologic diseases. His laboratory studies the inherited genetic changes in DNA that increase susceptibility to disease. Blood cancers such as myeloproliferative neoplasms and myelodysplastic syndromes are traditionally thought to be acquired disorders, however there is increasing evidence that inherited genetic changes play a role. In addition, Dr. Braunstein studies non-malignant blood diseases including atypical hemolytic uremic syndrome (aHUS) and related thrombotic disorders such as APLS, TTP and HELLP syndrome which are caused in part by genetic mutations. His work has identified a germline variants in the ERBB genes that predispose to hematologic malignancies. In addition, his research group found that patients with catastrophic APLS and HELLP syndrome frequently harbor germline mutations in complement regulatory genes. This has led directly to clinical trials designed to test the efficacy of complement inhibitio...n in patients with these disorders. Dr. Braunstein continues to work toward translating the scientific findings from the laboratory into improved care and treatment for patients. view more
Charles W. Flexner Laboratory
A. Laboratory activities include the use of accelerator mass spectrometry (AMS) techniques to measure intracellular drugs and drugs metabolites. AMS is a highly sensitive method for detecting tracer amounts of radio-labeled molecules in cells, tissues, and body fluids. We have been able to measure intracellular zidovudine triphosphate (the active anabolite of zidovudine) in peripheral blood mononuclear cells from healthy volunteers given small doses of 14C-zidovudine, and have directly compared the sensitivity of AMS to traditional LC/MS methods carried out in our laboratory.
B. Clinical research activities investigate the clinical pharmacology of new anti-HIV therapies and drug combinations. Specific drug classes studied include HIV reverse transcriptase inhibitors, protease inhibitors, entry inhibitors (selective CCR5 and CXCR4 antagonists), and integrase inhibitors. Scientific objectives of clinical studies include characterization of early drug activity, toxicity, and pharmacok...inetics. Additional objectives are characterization of pathways of drug metabolism, and identification of clinically significant harmful and beneficial drug interactions mediated by hepatic and intestinal cytochrome P450 isoforms. view more
Colleen Koch Lab
Research in the Colleen Koch Lab covers a range of interdisciplinary topics, particularly within anesthesiology and critical care medicine. Our studies have explored topics such as hospital-acquired anemia, cardiac anesthesia, cardiac herniation, red blood cell storage and process improvement in cardiac surgery.
David Sullivan Lab
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.
Edgar Miller Lab
Research in the Edgar Miller Lab focuses on nutrition, hypertension and kidney disease. Current projects include a National Heart, Lung, and Blood Institute study on dietary carbohydrate and glycemic index effects on markers of oxidative stress, inflammation and kidney function; and a National Institute of Diabetes and Digestive and Kidney Diseases randomized controlled trial that examines the effects of omega-3 fatty acid supplementation on urine protein excretion in diabetic kidney disease.
The Frederick Sieber Lab studies the impact of sedation on geriatric surgical patients—especially those undergoing orthopaedic or pelvic procedures—with the goal of preventing postoperative delirium. We are using electroencephalography to investigate the effect of sedation depth during spinal anesthesia. We are also working to determine the effects of using propofol for sedation in elderly patients as well as the effects of robotics and surgical positioning on cerebral blood flow.
Gail Daumit Lab
Research in the Gail Daumit Lab is devoted to improving overall health and decreasing premature mortality for people with serious mental illnesses, such as schizophrenia and bipolar disorder. We have conducted observational studies to determine and convey the burden of physical health problems in this vulnerable population, and are currently leading a randomized trial funded by the National Heart, Lung, and Blood Institute to test a comprehensive cardiovascular risk reduction program in people with serious mental illness.
Dr. Haughey directs a disease-oriented research program that address questions in basic neurobiology, and clinical neurology. The primary research interests of the laboratory are:
1. To identify biomarkers markers for neurodegenerative diseases including HIV-Associated Neurocognitive Disorders, Multiple Sclerosis, and Alzheimer’s disease. In these studies, blood and cerebral spinal fluid samples obtained from ongoing clinical studies are analyzed for metabolic profiles through a variety of biochemical, mass spectrometry and bioinformatic techniques. These biomarkers can then be used in the diagnosis of disease, as prognostic indicators to predict disease trajectory, or as surrogate markers to track the effectiveness of disease modifying interventions.
2. To better understand how the lipid components of neuronal, and glial membranes interact with proteins to regulate signal transduction associated with differentiation, motility, inflammatory signaling, survival, and neuronal excitab...ility.
3. To understand how extracellular vesicles (exosomes) released from brain resident cells regulate neuronal excitability, neural network activity, and peripheral immune responses to central nervous system damage and infections.
4. To develop small molecule therapeutics that regulate lipid metabolism as a neuroprotective and restorative strategy for neurodegenerative conditions. view more
