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. view less
Research in the Allan Gottschalk Lab focuses on the mechanisms behind neuropathic pain, chronic pain related to nerve injury. We are investigating biophysical models of the impact of general anesthesia on the central nervous system; informational aspects of sensory perception and the representation of sensory input; nonlinear dynamics of respiratory pattern generation; and acute perioperative pain.

The Center for Nanomedicine engineers drug and gene delivery technologies that have significant implications for the prevention, treatment and cure of many major diseases facing the world today. Specifically, we are focusing on the eye, central nervous system, respiratory system, women's health, gastrointestinal system, cancer, and inflammation.
We are a unique translational nanotechnology effort located that brings together engineers, scientists and clinicians working under one roof on translation of novel drug and gene delivery technologies
Research in the Elizabeth Tucker Lab aims to find treatments that decrease neuroinflammation and improve recovery, as well as to improve morbidity and mortality in patients with infectious neurological diseases. We are currently working with Drs. Sujatha Kannan and Sanjay Jain to study neuroinflammation related to central nervous system tuberculosis – using an animal model to examine the role of neuroinflammation in this disease and how it can differ in developing brains and adult brains. Our team also is working with Dr. Jain to study noninvasive imaging techniques for use in monitoring disease progression and evaluating treatment responses.
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 less
The Human Brain Physiology and Stimulation Laboratory studies the mechanisms of motor learning and develops interventions to modulate motor function in humans. The goal is to understand how the central nervous system controls and learns to perform motor actions in healthy individuals and in patients with neurological diseases such as stroke. Using this knowledge, we aim to develop strategies to enhance motor function in neurological patients.
To accomplish these interests, we use different forms of non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), as well as functional MRI and behavioral tasks.
Recent advances in molecular and cellular biology, the emergence of more sophisticated animal models of human disease and the development of sensitive, high-resolution imaging systems enable the study of pathophysiology noninvasively in unprecedented detail. The overall goal of our work is to develop new techniques and agents to study human disease through imaging. We concentrate on two areas, i.e., cancer and central nervous system processes. Our work extends from basic chemical and radiochemical synthesis to clinical translation.
