I am interested in the evolution of adaptive characters in a group of fishes known as Atherinomorpha. Currently, I am using molecular phylogenetics, scanning electron microscopy, and comparative transcriptomics, to understand the evolution of egg characters and the genetic basis of diapause in seasonal killifishes. Diapause is defined as a reversible delay in development that often occurs to cope with abiotic environmental stress or ensure emergence during a time of sufficient food resources. Seasonal killifishes live in bodies of water that are subject to annual desiccation. When the habitat dries up, all the adults die. Fortunately, they have evolved to lay their eggs in the substrate, which can survive via diapause until the wet season. Understanding this diapause will lead to a deeper understanding of the development and evolution of these fishes.
