My research involves a comprehensive analysis of the evolutionary mechanisms underlying adaptive phenotypic variation across a rapidly diversifying lineage of butterflies, with the central goal of understanding the ecological and evolutionary processes that shape temporal and spatial patterns of biodiversity.
My previous research at UC-Irvine focused on how natural and sexual selection work together to favor the evolution of specific animal phenotypes, how aposematic signaling may drive the evolution of social behavior in the context of visual ecology, and how specialized visual systems coevolve with specialized visual cues.
