Dr. Gill’s novel findings demonstrate the mechanisms underlying neurological symptoms and deficits in military personnel with TBIs, as well as athletes with concussions. Her research laboratory uses leading edge technology to identify and link omic biomarkers to neuronal damage through brain imaging methods that are unique to the NIH. Her line of research will prove enduring as she continues to develop methods for identifying brain injured patients who are at risk for a poor recovery and her discoveries are providing the foundation for early interventions to prevent the often irreversible symptoms resulting from post-TBI neurological damage.
14-NR-0032 An Investigation of the Biological and Neuronal Mechanisms of Post-Traumatic Stress Disorder, Depression, and Post-Concussive Syndrome Onset Following a Traumatic Brain Injury
Dr. Jessica Gill’s interest in research began during her nursing undergraduate (B.S.N.) career, during which she volunteered with women and children whose lives were negatively affected by violence. She observed that this extreme stress resulted in differing outcomes with some women being substantially impaired, whereas others were able to recover. She questioned the mechanisms underlying these divergent responses to extreme stress. This line of questioning led her to pursue a graduate degree (M.S.) from Oregon Health and Science University in psychiatric nursing, which included clinical training in the PTSD program at the U.S. Department of Veterans Affairs.
Research questions about trauma and resiliency were amplified during her work with Vietnam veterans who remained impacted by their combat service decades after returning home. Based on these volunteer and clinical experiences, she decided to pursue a doctorate at Johns Hopkins University’s School of Nursing. Her dissertation research demonstrated the presence of high rates of PTSD in urban health care seeking women, and that a PTSD diagnosis was associated with perceived health declines as well as with higher concentrations of inflammatory markers and a dysregulation of endocrine functioning.
Following completion of her Ph.D., she obtained a post-doctoral fellowship at the National Institute of Nursing Research (NINR) to better understand the biological mechanisms of PTSD and depression, finding central and peripheral alterations in the in-vivo functioning of both immune and endocrine systems. This line of research also led her to become a Clinical Investigator in the Center for Neuroscience and Regenerative Medicine (CNRM). She also is involved in leading national biomarker studies in athletes, military personnel and civilians. In these positions, she advises in the design and implementation of biomarker studies to ultimately improve the care of individuals with concussions and TBIs.
