Ian M. Hamilton studies social behavior in animals, combining mathematical models with field and lab studies of cooperation, dominance hierarchies, and conflict, often using group-living fish (such as cichlids) as a model system. His work links behavioral decisions (like helping, fighting, or vigilance) to underlying hormone and brain-signaling systems, and also includes theoretical work on game theory and habitat/resource use. Prospective students would engage with both quantitative modeling of animal social decisions and empirical fieldwork or physiology on social fish species.
Publication output has gradually declined from a peak of around 7-8 papers per year in 2017-2018 to roughly 2-4 papers per year in recent years.
