Professor Hultgren teaches Invertebrate Zoology (BIOL 235), Biology II: Ecology and Evolution (BIOL 162/172), and Marine Biology (BIOL 275).

Professor Hultgren studies ecological and behavioral diversity in marine invertebrates, and how species and trait diversity affect community structure.  She uses phylogenetic methods, field experiments, and laboratory assays to examine these topics in a wide range of marine organisms, with a recent focus on host-symbiont and host-parasite systems.  Most recently, her research examined how phylogenetic relatedness and social behavior interact to structure communities of symbiotic sponge-dwelling snapping shrimp in Caribbean coral reefs.
