Nematodes are among the most abundant and simplest of animals on Earth. The top one inch of soil is estimated to contain over 500 million individuals per acre. The abundance and simplicity of these animals makes them ideal for studying detailed changes in cell morphology. We use a combination of light and electron microscopy to examine how anatomical changes occur in response to environment and how evolution has sculpted new anatomical variation. We also collaborate on projects categorizing nematode species in agricultural and natural settings.
