Giulia Baldini, M.D., Ph.D.
Website: Research Profile

My research focuses on Melanocortin-4 receptor, a G-protein coupled receptor involved in appetite control.

Steve W. Barger, Ph.D.
Website: Research Profile

My lab is focused on Alzheimer’s disease. Current research is examining the role of diabetes-related disruptions in glucose metabolism and the impact this has on brain function. Evidence indicates that both Alzheimer’s and diabetes involve processes connected to inflammation, which has been another of my longstanding areas of research.

Keith Bush, Ph.D.
Website: Research Profile

Dr. Bush has focused his research interests on machine learning and control theoretic approaches to real-time human neuroimaging, using both real-time fMRI and fMRI-based neurofeedback to understand and exploit volitional regulation of cognitive processes. By understanding how the human brain decodes and integrates neurofeedback signals into its cognitive control processing, Dr. Bush hopes to optimize neuroimaging studies and develop new control-theoretic diagnostic instruments and treatments for emotional dysregulation and attendant pathologies, such as addiction.

Gwen Childs, Ph.D., FAAA
Website: Research Profile

We are actively studying the role of leptin in the regulation of pituitary cells. We have discovered that leptin may be a post transcriptional regulator for target hormones, receptors and transcription factors. Our studies range from whole animal to molecular approaches and a student would get training in a number of complementary protocols. Our studies are translationally relevant to growth, obesity, reproduction, and fetal and neonatal development.

David Davies, Ph.D.
Website: Research Profile

Neurodevelopmental and neurodegenerative sequelae resulting from traumatic brain injury. Current research is focused on medical education issues.

Paul Drew, Ph.D.
Website: Research Profile

Dr. Drew conducts research in the field of Neuroimmunology. Normally, immune activity in the brain is limited. However, in diseases including multiple sclerosis, Alzheimer’s disease, and alcohol abuse activated immune cells are observed in the brain. These immune cells produce cytokines which may be toxic to brain cells as well as chemokines which direct cells to sites of inflammation, resulting in neuropathology. Dr. Drew’s research involves modern cellular and molecular biology techniques.

The Department of Obstetrics and Gynecology has active basic and clinical research in the divisions of Maternal-Fetal Medicine, General Obstetrics & Gynecology, and Gynecologic Oncology. Our mission is to create a center of excellence in women’s health to serve the people of Arkansas. Our goal is to expand our research activities by utilizing supportive internal resources and collaboration, and continue to seek external funding.

William E. Fantegrossi, Ph.D.
Website: Research Profile

Research in my laboratory is currently focused on several categories of emerging drugs of abuse, including synthetic cannabinoids (constituents of K2/”Spice” smoking blends), analogues of cathinone (present in “bath salts” preparations), and novel arylcyclohexylamines (related to PCP and ketamine.) In an effort to better understand the biological actions of these emerging drugs of abuse, we use behavioral pharmacology techniques in rodents to compare these compounds with more the well-known drugs of abuse that these emerging drugs are designed to mimic (such as the phytocannabinoid delta9-THC, psychostimulants like MDMA and methamphetamine, and PCP).

Abdallah Hayar, Ph.D.

G. Andrew James, Ph.D.
Website: Research Profile

By understanding how the healthy brain encodes cognition, Dr. James seeks to translate this technology into patient care and better inform clinical decision-making. Dr. James believes that understanding individual differences in the neural encoding of traits such as craving, impulsivity, and working memory are crucial for understanding how these brain-behavior relationships are disrupted with addiction.

Tara Johnson, M.D.
Website: Research Profile

Dr. Johnson’s research work is focused on the early identification of infants at high risk for the development of cerebral palsy and other neurodevelopmental disorders. Her KL2 Mentored Research Career Development Award project will transform current clinical practice at Arkansas Children’s Hospital by implementing the General Movement Assessment, a low-cost diagnostic tool, to identify Neurodevelopmental Disabilities at an earlier age in high-risk infants.

Linda Larson-Prior, Ph.D.
Website: Research Profile

The focus of my laboratory (http://eon.wustl.edu) is on the dynamic neural network re-configurations that occur as the brain changes its state under both normal conditions such as sleep, and in abnormal conditions such as induced shifts in conscious awareness (anesthesia) or pathological shifts in cognitive awareness (fluctuating consciousness, sleep parasomnias and neurodegenerative disease states).  We have developed the use of simultaneous acquisition of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) to help us better understand these shifts in network connectivity and function as the brain shifts state over the course of 24 hours.  We have extended our neuroimaging (fMRI) data to examine changes in large-scale functional brain network connectivity with neural state using graph theoretical techniques.  As part of the Human Connectome Project, my laboratory worked with a large international team to define the time-varying connection patterns in over 1200 normal adult human subjects (http://www.humanconnectome.org).  The laboratory maintains extensive collaborations with other research teams interested in the use of functional network methods in EEG, MEG, fMRI and EEG/fMRI to examine brain dynamics in both health and disease.

Angus Macnicol, Ph.D.

My main research interests include the use of laser thermal ablation for brain tumors and understanding the immune microenvironment.

Kimberly Elizabeth Stephens, Ph.D., MPH
Website: Research Profile

The activity of primary sensory neurons is critical for the development and maintenance of persistent pain states. Following peripheral injury, primary sensory neurons show complex activity-dependent plasticity as a result of prolonged noxious stimuli and ectopic discharges. This altered activity in the primary sensory neurons is transmitted to spinal dorsal horn neurons and ultimately to the brain which results in persistent pain in a proportion of patients. While genetic studies have advanced our knowledge of nociceptive pathways, our current understanding does not explain variations in the susceptibility of individuals to the development of this cancer-related persistent pain. Common genetic variations in pain phenotypes show inconsistencies across studies6 and have not facilitated the development of new treatments. Epigenetic variations within the genome are known to cause misregulation of protein at a cellular level which may modulate nociception. My long term goal is to determine the contribution of epigenetic pathways to enhanced pain sensitivity and the establishment of cancer-related persistent pain. Specific research questions that I am eager to explore include (1) the association between altered chromatin structure in the dorsal root ganglion and cancer-related pain, and (2) cell-type specific changes in chromatin accessibility associated with chemotherapy-induced peripheral neuropathy.
