I am fascinated with cooperation. Cooperation occurs in a multitude of situations from human romantic relationships, professional relationships, academia, and even in non-human, animal social groups. Why individuals cooperate and how individuals choose whom to cooperate with are questions that drive my current studies in graduate school. Particularly, I am interested in the cooperation that occurs when cost is immediate, but future benefits are uncertain. As a theorist and empiricist, I will tackle these questions using mathematical modeling, and test those models experimentally. Because cooperative groups commonly occur in fish, and fish are easily manipulated in the field and in laboratory studies, I will use freshwater and marine fish as model organisms to examine cooperation.
