If the mind and body are connected what happens when that connection is broken? To answer this question I conduct research using behavioral and pharmacological methods to study acetaminophen’s effect on aggressive behavior and effort. Additionally, I explore the mechanisms by which acetaminophen affects different behavior. I’m also interested in adversity and resiliency. Why do some people thrive in the face of adversity and how can people become psychologically tough to succeed? I’m interested in the role of life history and relationships in the development of resiliency.
