Areas of Interest

The richness and diversity of insects fascinate me, particularly the diversity of caddisflies, or Trichoptera. As aquatic larvae, caddisflies build remarkable silken nets and portable cases of many different styles and materials. Adults, too, are very diverse in their size, color, and morphology. My curiosity for these insects is fueled by the many new species being discovered around the world and my desire to describe this diversity.

My specific area of expertise is in the systematics and taxonomy of Neotropical caddisflies. My research involves field work, descriptive and alpha taxonomy, and revisionary and phylogenetic studies. I am also interested in general systematic theory and methodology, historical biogeography, conservation, and museum management and administration.
