Research

My research combines empirical ecology, ecological theory, and computational modelling to understand how environmental change shapes biodiversity, species interactions, and ecosystem stability.

Aquatic communities under environmental change

I examine how environmental gradients and habitat change reorganise aquatic communities. Across wetlands, seagrass ecosystems, coastal habitats, and plankton communities, my work explores how salinity, eutrophication, ecological restoration, and invasive species affect biodiversity, trophic structure, and ecosystem functioning.

Food-web structure and stability

I investigate how food-web structure translates species interactions into community-level stability. By combining empirical networks with dynamical models, I test how energetic constraints, interaction strengths, biomass distributions, and body-size structure influence persistence, resilience, and the ecological importance of particular species and interactions.

Traits and eco-evolutionary dynamics

I develop trait-based models to understand how adaptation changes competition, predation, and species coexistence. This work examines when ecological trade-offs and coadaptation stabilise interactions, reduce bistability, or generate alternative community states in mixotroph–resource and intraguild predation systems.

Chemical stress and ecological prediction

My current research connects variation in species chemical sensitivity with impacts at the food-web level. One project tests whether body mass, functional groups, and phylogenetic relationships can improve sensitivity prediction across aquatic species. A second combines chemical exposure, species occurrence, sensitivity, and trophic interactions within site-specific freshwater food webs to assess biodiversity loss, community vulnerability, resistance, and recovery.
