Dr. Hager came to Cazenovia College in 2000, bringing with her years of experience in field research and instruction. Her biological specialties are behavioral ecology and entomology, with a special interest in dragonflies and solitary wasps and bees.  Several of the undergraduate students working in her major research areas have presented and published their research.  Dr. Hager also has guided smaller research projects on salamander diversity and habitat selection, aquatic macroinvertebrate diversity and ecology, lichen diversity on different tree species and rock types, protist diversity of lichens and mosses, behavioral enrichment in zoos, and changes in individual insects' behaviors in relation to size and age.
