Nutrient-Based Strategies to Increase Resilience to Stress

Post-traumatic stress disorder (PTSD) and chronic neuropathic pain (CNP) are frequently observed following a traumatic event. Clinical practice suggests that these two conditions co-occur at a high rate and may interact in such a way as to negatively impact the course of both disorders. Understanding the underlying shared mechanisms that contribute to both disorders is required for the discovery of novel treatments. Scientifically, The Fig NeuroLab is primarily focused on understanding the molecularmechanisms by which dietary lipids regulate susceptibility or resilience to stress and pain. In particular, we are interested in tracing the neurobiological substrates that control individual vulnerability to co-morbid PTSD and CNPA common thread among our studies is the use of clinically relevant PTSD and painmodels combined with animal behavior, electrophysiology, celland molecular neurobiology, confocal microscopy, neuroimaging, and nutrimetabolomics to define the relative contribution of dietary omega-3 fatty acids towards neuronal plasticity and resilience.From a translationalperspective, we seek to rapidly advance our discoveries in the lab and clinic into effective functional foods and nutraceutical interventions that improve the rehabilitation potential of affected patients. Academically, our laboratory is focused on promoting diversity in the biomedical research workforce. The overarching goal is to enhance the development of talented neuroscientist from all population sectors and academic levels.
