Torrance Hanley is an aquatic community ecologist, whose research focuses on the role of diversity in trophic interactions in freshwater and marine systems. She is also interested in how inter- and intra-specific diversity of producer and consumer species impacts population and community dynamics, trophic interactions, and ecosystem function. Kimberly La Pierre is a terrestrial community ecologist, whose research focuses on the effects of global change on trophic interactions and ecosystem function. She is also interested in drivers of plant invasions, including the role of herbivory and microbial mutualisms.
