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.

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.

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.

The Lau Lab uses a combination of computational and experimental approaches to study the atomic and molecular details governing the function of protein complexes involved in intercellular communication. We study ionotropic glutamate receptors (iGluRs), which are ligand-gated ion channels that mediate the majority of excitatory synaptic transmission in the central nervous system. iGluRs are important in synaptic plasticity, which underlies learning and memory. Receptor dysfunction has been implicated in a number of neurological disorders.

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.

Research in the Alfredo Kirkwood Laboratory is directed toward elucidating the basic mechanisms by which visual experience can modify cortical connections in the visual cortex and how those mechanisms are regulated. In visual cortical slices, we investigate two forms of activity-dependent synaptic plasticity: long-term potentiation (LTP) and long-term depression (LTD). These two forms of synaptic plasticity are currently the most comprehensive models of the elementary mechanisms underlying naturally occurring plasticity. We are currently focused on how synaptic inhibition and the action of neuromodulators regulate the induction of LTP and LTD during development. We hope to gain a better understanding of how naturally occurring plasticity is regulated.

The Aliaksei Pustavoitau Lab conducts research on models and mechanisms of impaired consciousness in patients who have suffered acute brain injury. Examples of our work include a study on the mechanisms of neurologic failure in critical illness and another on the use of intensivist-driven ultrasound at the PICU bedside. We also have a longstanding interest in patient safety and quality of care in the ICU setting.

Research in the Alicia Arbaje Lab aims to help older adults maintain dignity and quality of life as they age. We are particularly interested in creating health care systems to improve safety and outcomes for older adults.

The Aline Charabaty Lab performs clinical research on Inflammatory Bowel Disorder.

Research in the Alison E. Turnbull Lab focuses on patient-clinician interactions. We study decision-making processes for ICU patients and their families and focus on the long-term outcomes of ICU survivors. Additional research examines ways to improve end-of-life care for patients.
