  • Erica Johnson Lab

    Research in the Erica Johnson Lab investigates infection control in military deployment environments as well as infections that are associated with combat trauma. We explore topics such as HIV outcomes, gender-based health issues and disparities in care.

    Research Areas: gender-based health issues, infectious disease, combat trauma, HIV, deployment infection control, health disparities

  • Fuchs Laboratory

    The Fuchs Laboratory uses cellular electrophysiology, immunolabeling and electron microscopy to study synaptic connections between sensory hair cells and neurons in the cochlea. One effort focuses on an unusual cholinergic receptor that mediates efferent inhibition of hair cells, driving discovery of the molecular mechanisms, and offering a target for protection against acoustic trauma. A second topic concerns the small number of unmyelinated "type II" afferent neurons whose synaptic connectivity and response properties argue for a role as the pathway for noxious (too loud) sound. Our studies are motivated by curiosity about fundamental mechanisms, and to provide a foundation for understanding cochlear pathogenesis.

    Research Areas: synaptic connections, immunolabeling, neurons, elecrophysiology, audiology, cellular electrophysiology, hearing loss, electron microscopy, cochlea, cochlear pathogensesis

  • Ocular Motor Physiology Laboratory

    Our research is directed toward how the brain controls the movements of the eyes (including eye movements induced by head motion) using studies in normal human beings, patients and experimental animals. The focus is on mechanisms underlying adaptive ocular motor control. More specifically, what are mechanisms by which the brain learns to cope with the changes associated with normal development and aging as well as the damage associated with disease and trauma? How does the brain keep its eye movement reflexes properly calibrated? Our research strategy is to make accurate, quantitative measures of eye movements in response to precisely controlled stimuli and then use the analytical techniques of the control systems engineer to interpret the findings.

    Research areas: 1) learning and compensation for vestibular disturbances that occur either within the labyrinth or more centrally within the brain, 2) the mechanisms by which the brain maintains correct alignment of the eyes to prevent d...iplopia and strabismus, and 3) the role of ocular proprioception in localizing objects in space for accurate eye-hand coordination.

  • Robert Stevens Lab

    The Robert Stevens Lab seeks to generate a comprehensive anatomical and functional map of neural injury and repair following incidents such as trauma, stroke, anoxia and sepsis. Several projects have evaluated the relationship between critical illness and central or peripheral nervous system dysfunction. Ongoing projects deploy quantitative brain mapping to probe recovery of consciousness and cognitive function in patients who have experienced acute neurologic insults from trauma, stroke, cardiac arrest and sepsis.
