Interests and Expertise

Broadly, my research areas are molecular ecology (the use of molecular genetic tools to answer ecological questions) and conservation biology. I am particularly interested in amphibians, as they can be important indicators of habitat degradation and other environmental disturbances ("canaries in the coal mine"). I am currently interested in the use of molecular tools for two major purposes. First, such analyses can be highly informative regarding the conservation status of imperiled populations. For example, I have used genetic data to quantify population isolation and its relation to human modification of the surrounding landscape. Second, I use genetic data to identify genomic composition of unisexual (all female) Ambystoma salamanders. These salamanders "steal" sperm from co-occurring species, resulting in numerous polyploid biotypes (genome combinations). This unique mode of reproduction, known as kleptogenesis, likely originated 5 million years ago. My current research focuses on the ecological consequences and conservation implications of this complex system.
