Candace L. Floyd, Ph.D., received her M.S. from Medical College of Virginia/Virginia Commonwealth University in 1998 where she studied traumatic brain injury using in vivo rodent models under the tutelage of Bruce G. Lyeth, Ph.D. She received her Ph.D. from the same institution in 2000, under the mentorship of Earl Ellis, Ph.D., and focused her research on in vitro mechanical strain injury in astrocytes. She conducted her post-doctoral training in traumatic CNS injury at the University of California, Davis from 2001-2004. In 2004, she became an Assistant Professor in the Department of Neurological Surgery at the University of California, Davis. In 2006, she moved to the University of Alabama at Birmingham, where she joined the Center for Glial Biology in Medicine and is an Assistant Professor in the Department of Physical Medicine and Rehabilitation. The central focus of her research is to understand glial-neuronal interactions in traumatic brain and spinal cord injury. Recent work from the Floyd laboratory evaluates the protective actions of 17b-estradiol in traumatic CNS injury. Other work evaluates bioengineering approaches to regeneration and repair. The Floyd lab also investigates glial-neuronal interactions in neuropathic pain after CNS injury. She has served as an invited instructor in the Reeve-Irvine Spinal Cord Injury Techniques Course, as an ad-hoc member of NIH study sections, and has also reviewed grant applications for the Department of Defense and the Veteran's Administration. She frequently reviews manuscripts for several neuroscience journals, including the Journal of Neurotrauma and is an active member of the National Neurotrauma Society.

Research/Clinical Interest
Neuronal-Glial Interactions in Traumatic Brain and Spinal Cord Injury
Millions of people a year suffer a traumatic brain or spinal cord injury (TBI or SCI); and in the blink of an eye, their lives may be changed forever. The current clinical repertoire for treating CNS injury is extremely limited. In fact, there are no pharmacological interventions to treat TBI and only one drug with questionable efficacy for use in SCI. Most previous research in CNS injury has focused on neuroprotection, and has discounted the role of glial cells in injury pathology. The central hypothesis of our research is that understanding of the complex interaction of glial and neuronal cells in the pathophysiology of traumatic CNS injury will lead to novel, effective therapeutic interventions. On-going projects include: a) estrogens, phytoestrogens, and selective estrogen receptor modulators (SERMs) as potential protective agents in TBI and SCI b) bioengineering approaches to promote regeneration and repair of the injured spinal cord c) mechanisms and implications of glial cell death in traumatic brain and spinal cord injury d) understanding neuronal-glial interactions in neuropathic pain after spinal cord injury e) elucidating pathological mechanisms underlying lasting cognitive deficits after mild TBI (concussion)
