Hannah Griebling M.S. 2019. "Intraspecific Variation in Cognitive Traits in a Swordtail Fish (Xiphophorus multilineatus)"
Danniel D'Amore, Ph.D. 2018. Danny D'Amore is interested in the link between behaviors, personalities, and the success of invasive species. She uses the X. helleri and X. helleri-maculatus system to investigate how the invasive process, hybridization, and linebreeding can shape these behaviors and influence the path to invasive success.

His main research interests are in Behavioral Ecology, with a more specific focus on the effects of parental care and sexual selection on the evolution of mating systems in general, and alternative reproductive strategies in particular.
