Ari Berkowitz, Associate Professor of Zoology (Ph.D., Washington University, 1993); e-mail: ari<<at>>ou.edu. Neural mechanisms of sensorimotor integration, behavioral choice, motor pattern generation. He conducts electrophysiological, neuroanatomical, and pharmacological experiments on the turtle spinal cord control of swimming and scratching, to address how the nervous system selects and generates an appropriate behavior for each circumstance an animal faces.

Robert H. Cichewicz, Assistant Professor of Chemistry and Biochemistry (Ph.D., Michigan State University, 2002); e-mail: rhcichewicz<<at>>ou.edu.  Natural product drug discovery of small molecule protectants against toxicity attributable to misfolded and aggregation prone neurotoxic proteins associated with Huntington’s and Parkinson’s diseases.  Application of NMR-based metabolomics methods to identify novel disease targets associated with neurodegenerative disorders.  Utilization of metabolomics as a primary assay tool for the detection of new natural product neuroprotectants.

David S. Durica, Professor of Zoology (Ph.D., University of Connecticut, 1977); e-mail: ddurica<<at>>ou.edu. Endocrine modulation of gene expression; nuclear receptor gene structure and function; paracrine signaling in developmental regulation; evolution of multigene families.   His research addresses the physical mechanisms through which hormones coordinate varied genetic and physiological responses.  Efforts are currently focused on characterizing the transcription factors involved in genomic responses to steroid and retinoid signaling, and cascades of gene expression triggered by an endocrine signal.

Douglas D. Gaffin, Associate Professor of Zoology and Dean, University College
(Ph.D., Oregon State University, 1994); e-mail: ddgaffin<<at>>ou.edu. Sensory, electrophysiology, neurobiology, behavior, scorpions. His lab is interested in how animals acquire and process information about their sensory environments.  They focus on sandscorpions, owing to their clean native habitat, slow walking behavior, and fluorescent cuticle.  The chemo-, mechano-, and visual sensory systems of these animals are all approachable to physiological investigation and we use a combination of behavioral, morphological, and electrophysiological techniques to deduce circuitry and neural coding of sensory information in this ancient group of animals.

Rong Z. Gan, Professor of Biomedical and Mechanical Engineering and Adjunct Professor of Physiology, Health Sciences Center (Ph.D., University of Memphis, 1992); e-mail: rgan<<at>>ou.edu. Cell, tissue and organ biomechanics, implants and implantable hearing devices, theoretical modeling of physiological systems. Her research focuses on relationships between morphological structure, mechanical properties, and function of middle ear and inner ear in normal, pathological and implanted conditions. She conducts acoustic-mechanical coupled measurements and computer modeling of auditory systems in human temporal bones and animals to analyze sound transmission mechanism. Biomechanical properties of soft and hard tissues are measured through the micro-tensile material testing system, imaging analysis, and nanoindentation test.

Randall S. Hewes, Associate Professor of Zoology and Adjunct Associate Professor of Cell Biology, Health Sciences Center (Ph.D., University of Washington, 1993); e-mail: hewes<<at>>ou.edu. Neuropeptides, Development, Molecular Genetics, Genomics, Behavior. Neuropeptides are chemical signals that are secreted by nerve cells to control key functions of the brain and many other tissues.  Disruptions in neuropeptide signaling are associated with human diseases, such as obesity, diabetes and cancer.  The Hewes laboratory focuses on the mechanisms by which cells acquire, maintain and regulate neuropeptides, and how changes in neuropeptide signaling control animal behavior.  This research exploits the powerful molecular, genetic, and genomic techniques available in a model organism, the fruit fly, Drosophila melanogaster.

Rosemary Knapp, Associate Professor of Zoology (Ph.D., Arizona State University, 1996); e-mail: rknapp<<at>>ou.edu. Behavioral neuroendocrinology, evolutionary endocrinology, comparative physiology. Her research aims to understand various factors influencing behavioral variation, particularly behaviors related to reproduction.  She combines the approaches of behavioral endocrinology, neuroendocrinology and physiological ecology to study the physiological bases of behavior both in the field and in the laboratory in a variety of vertebrate species.  The ultimate goal of this research is to understand the neuroendocrine changes that have occurred as new patterns of reproductive behavior have evolved.

Thomas S. Ray, Professor, Department of Zoology (Ph.D., Harvard University, 1981); e-mail: tray<<at>>ou.edu.  Neuropsychopharmacology.  The use of psychedelic drugs as probes to reveal the chemical architecture of the human mind.  The diverse set of psychedelics collectively represents a rich set of tools for probing the chemical architecture of the human mind.  These tools can be used to explore components of the psyche whose discreteness is normally obscured by their being embedded in the complete tapestry of the mind.  By activating specific components of the mind, they are made to stand out against the background of the remainder of the psyche.  Thus both their discreteness and their specific contribution to the psychic whole can be better appreciated.  That the revealed mental elements can be pharmaceutically manipulated, suggests that they may be naturally modulated through chemical systems.  These receptor mediated mental components are the distinct elements from which the mind has been fashioned through evolution.

Robert L. Rennaker, Assistant Professor of Aerospace & Mechanical Engineering (Ph.D., Arizona State University, 2002); e-mail: rennaker<<at>>ou.edu. Neural Engineering and Prosthetics.  His research aims 1) to develop the tools and methods necessary to directly communicate with the central nervous system for the purpose of understanding neural processing and for the development of neural prosthetic devices; 2) to study multi-unit processing of sensory information at the cortical level to guide prosthetic development.

Ingo Schlupp, Assistant Professor of Zoology (Dr. rer.nat University of Hamburg, 1995); e-mail: schlupp<<at>>ou.edu. Ecology and evolution of sex. His group is interested in mainly two questions: 1) What is the short term benefit of sexual recombination and how can closely related sexual and asexual organisms co-exist? The model they use is a unisexual fish, the Amazon molly (Poecilia formosa). 2) Can extreme environmental conditions lead to speciation? To address this they study fishes in a toxic cave in Mexico. His research tries to integrate proximate and ultimate approaches.

Regina M. Sullivan, Professor of Zoology (Ph.D., City University of New York, 1983); e-mail: rsullivan<<at>>ou.edu. Development of the neural mechanisms of learning, amygdala and fear conditioning, norepinephrine and locus coeruleus, olfaction. Her lab works on both newborn humans and rats within the context of mother-infant interactions highlighting unique circuitry of learning in infancy. Recent work includes an animal model of child abuse.

James N. Thompson, jr., David Ross Boyd Professor of Zoology (Ph.D., University of Cambridge, 1973); e-mail: jthompson<<at>>ou.edu. Mutation rate under stress, genotype x environment interaction, experimental quantitative genetics, aging.  His lab is interested in factors that influence mutation rate, especially those occurring premeiotically that yield clusters of identical mutations at the same time.  This is related to his work in the larger area of the genetics of adaptation and developmental stability under stress, genotype x environment interactions, and genetic influences on homeostasis and aging.  The lab uses Drosophila as a model organism, with special attention to patterning of wing veins and peripheral sensory structures on the cuticle.

Han Wang, Assistant Professor of Zoology (Ph.D., Wayne State University, 1996); e-mail: hwang<<at>>ou.edu. He studies molecular genetics and genomics of zebrafish (Danio rerio) circadian rhythmicity, retinal, pineal and hematopoietic development. He is also interested in evolution of development as well as evolution of vertebrate genomes.

Ann H. West, Professor of Biochemistry (Ph.D. Yale University, 1991); e-mail: awest<<at>>ou.edu. Signal transduction mechanisms, protein phosphorylation, protein structure determination by X-ray crystallography. In general, her laboratory is interested in the biochemical and structural basis of phosphorylation-dependent signal transduction systems.  In particular, her laboratory is studying a His-Asp phosphorelay signaling pathway in yeast that is involved in cellular responses to environmental stress.

Donald A. Wilson, Professor of Zoology (Ph.D., McMaster University, 1983); e-mail: dwilson<<at>>ou.edu. Neural mechanisms of sensory processing, neurobiology of memory, neurobehavioral development. His lab is interested in how sensory information (primarily olfaction) is encoded in the mammalian brain, and how experience shapes both information processing, functional neurocircuitry and behavior.

Bing Zhang, Assistant Professor of Zoology (Ph.D., Cornell University, 1995); e-mail: bing<<at>>ou.edu.  Molecular genetics of synaptic function and plasticity.  His lab uses the fruit fly (Drosophila melanogaster) as a model organism to dissect the cellular and molecular mechanisms of structural and functional plasticity of the synapse. Current research projects are focused on understanding 1) the role of SNAREs and clathrin-related molecules in the synaptic vesicle cycle and 2) the signaling pathways underlying neurodegeneration (such as ALS, Parkinson’s and Alzheimer’s disease).
