Brain-behavior relationships, synapse formation

Research Focus

Understanding the precise neural mechanisms that give rise to complex and conditional actions and behavioral responses requires study at molecular, cellular, and whole organism levels. Study of less complex and molecularly malleable organisms provides the foundation for understanding human behavior. The wolf spider is a novel and ideal model organism for the study of aggression and other complex predatory-related behaviors. My research focus involves characterizing conditional wolf spider behavioral aggression patterns that relate to hunger state, mapping and visualizing the underlying neural systems with confocal fluorescent microscopy, and identifying the role of particular neural peptides that control these action patterns.
