Research Interests

Mitochondrial Dysfunction and Cell Death in Traumatic Spinal Cord Injury
It has been well documented that widespread neuronal and glial cell death occurs following traumatic spinal cord injury. In addition, important advances have been made in understanding the intracellular pathways controlling cell death after injury. The goal of our research is to limit neuronal and glial cell loss and the resulting neurological deficits by blocking steps occurring early in the cell death process. Recently, we have focused our efforts on identifying the mitochondrial events responsible for regulating cell survival and death. We are particularly interested in identifying therapeutic agents that limit mitochondrial dysfunction as a means of promoting cell survival, and currently testing a novel agent targeting mitochondrial function in the acute phase of spinal cord injury. Our research program works closely with various Departments and Centers at the University of Kentucky and the Cardinal Hill Rehabilitation Hospital to ensure that highly promising lab bench discoveries reach the clinic.
