My research interests focus on two broader themes: 1) Invasive plant species and the mechanisms that underlie successful invasions in wetlands, and 2) Ecological interactions in communities. Under theme No. 1, I’m interested in how plant invasive species’ traits (such as rapid growth, large biomass, large litter deposition, and even genotype) trigger a cascade of effects that span from their interaction with co-occurring native species all the way up to ecosystem-level processes. Within this topic, I am exploring two important wetland plant invaders: cattails (Typha spp.) and common reed (Phragmites spp.). I also combine molecular tools (microsatellite markers) to answer ecological questions, mostly related to the identification of hybridizing invasive plant species. Under theme No. 2, I’m interested in: a) how communities respond to external disturbances (e.g., invaders, pollutants, urbanization), and b) how aquatic communities are fueled, either via primary production, detritus, or external inputs (i.e., spatial subsidies).
