RESEARCH AND SCHOLARLY INTERESTS
My interest in the anatomy of neurons has led to work in synaptology,
degeneration, and regeneration, as well as analyses of the levels of order found
in the neuronal organization of the CNS. My lab has focused on the neuronal
organization of the spinal cord, ocular motor nuclei and at present the
functional organization of the hypoglossal nucleus. Dr. Stephen Goldberg and I
are collaborating using intracellular electrophysiological characterization of
motoneurons followed by intracellular HRP labeling. Complete anatomical analysis
of these functionally characterized neurons is carried out in my laboratory.
These analyses have included total dendritic surface area determinations as well
as soma size and motoneuron topography studies. These investigations allow
direct comparison of the structure and function of motoneurons and demonstrate
the neuronal organization available for the control of movement.
I have received the VCU School of Dentistry Award for Outstanding Classroom
Instruction and the VCU School of Medicine Outstanding Teacher Award.
Videos of my lectures were published by The Continuing Education
Network, A Functional Anatomy of the Hand and Wrist, from the Upper Limb
Symposium, Sydney Australia; A Dissection of the Pelvic Cavity, from the
Symposium on Chronic Pelvic Pain, Chicago IL.
