My primary area research is aquatic entomology, which is the study of insects that live in rivers, lakes and wetlands. As a kid, I spent my weekends watching and collecting these “critters” in John McLaren Park in the middle of San Francisco, California. Insects have always fascinated me, especially the ones that live under water. I guess I’m still a kid when it comes to chasing six-legged critters!

Insects are useful organisms for answering important biological questions. Aquatic insects play critical roles in rivers and lakes. They serve as valuable food items for fish and waterfowl. We also use insects as “living pollution sensors; their presence or absence can tell us a lot about how clean the water is in lakes and streams. Some aquatic insects transmit harmful diseases, like malaria and encephalitis, to humans and other animals. Knowing how, when and where such insects live and breed can help control the spread of disease. Increasing our understanding about insects is a valuable scientific pursuit and fun, too.
