Student research in my lab is focused primarily on mate choice and parental behavior in tropical freshwater cichlid fish from South and Central America. We are currently studying the evolution of sexual dimorphism and sexual dichromatism (sexual selection) as it impacts mate choice in species of the genus Cryptoheros by videographic behavioral analysis of their social interactions in large colonies (mate choice and territoriality) and in controlled ‘multiple-choice’ single fish experiments.
