Research Interests

Professor Giza’s areas of research interest and active investigation include developmental TBI and its pathophysiology.

Ongoing studies include those examining impaired neurotransmission, altered developmental plasticity, acute alterations in metabolism, morphological injury, vulnerability to secondary insults and behavioral impairments. Basic research into post-traumatic brain activation, molecular signaling and experience-dependent plasticity are fundamental parts of the laboratory program. 

We are currently investigating the response of molecular signaling molecules after developmental TBI, and how post-injury environment may modulate the molecular and neuroplastic potential of the immature brain. Specifically, there appears to be an impairment of excitatory neurotransmission and activity-dependent neurotrophin expression that represent mechanisms underlying the injury-induced impairment of brain plasticity. 

Another basic research area spans the terrain between acute neuronal injury and delayed plasticity. Using induction of post-traumatic seizures as a secondary injury, we are studying the vulnerability of the injured immature brain. By conducting long-term behavioral, electrophysiological and morphological assessments of these subjects, we also gain insight into aberrant neuronal sprouting and epileptogenesis following TBI. 

In addition to the basic science approach to the problem of pediatric TBI, the group is currently engaged in establishing a translational/clinical program. This will be designed to capture physiological monitoring and imaging data from the acute hospitalization, with standardized outpatient clinic followup. One area of clinical investigation already underway is the study of neuropsychological function, anatomical imaging, functional brain mapping and white matter tract morphology across time in normal developing control children and in children recovering following moderate to severe TBI. A second clinical area under development will be the correlation of acute physiological variables (such as intracranial pressure, cerebral perfusion, magnetic resonance spectroscopy, acute white matter lesions, and early secondary insults) with neurological and behavioral outcomes. 

One important goal of the group is to translate research findings between laboratory and clinical arenas to gain better mechanistic insight into the physiological distinctions of pediatric TBI, and to better understand and to eventually facilitate how the developing brain recovers from TBI.
