The primary focus of this thesis centers around the examination of lipids to aid in the diagnosis, prognosis, and mechanistic understanding of traumatic brain injury (TBI). Lipids are important signaling molecules and play a critical role in energy storage as well as membrane structure and organization. Using mass spectrometry (MS) based methods to perform non-targeted metabolomic experiments with a focus on extraction of lipid metabolites, a rodent model is investigated to explore the feasibility of developing lipid biomarker panels to classify injury post-hoc across multiple severities. The developed methods are then used to study another biological system in order to show the broad applicability of lipidomics by investigating the effect of Karenia brevis allelopathy on two phytoplankton competitors.
