    Research interests

    The neural orchestration of motivated behaviors using sexual behavior and feeding behavior in Wistar rats as a model to unravel the complexity of reward and motivation. Currently studying the microstructural organization of temporal copulatory patterns and sexual motivation in Wistar rats.
