My research focuses on the study of strong fluctuations and structure in the abundance and assembly of species, emerging from the interactions and limited spatial flows of individuals and matter. These interactions and flows can explain sudden shifts in ecosystem health resulting from the propagation of disturbances. These shifts can emerge because (in)organic matter and individuals are coupled through both uptake/recycling (biogeochemical) and ecosystem engineering/disturbance cycles that often involve nonlinear and positive feedbacks, as well as fast-slow dynamics. Meta-ecosystem theories and ecosystem-based management still have to integrate these cycles to predict observed fluctuations in natural systems.

我的研究重点是研究物种丰度和组装中的强烈波动和结构，这些波动和结构来自个体和物质的相互作用和有限的空间流动。这些相互作用和流动可以解释由于扰动的传播而导致的生态系统健康的突然变化。这些变化的出现是因为有机物和个体通过吸收/再循环（生物地球化学）和生态系统工程/干扰周期耦合在一起，这些周期通常涉及非线性和正反馈以及快-慢动态。元生态系统理论和基于生态系统的管理仍然需要整合这些周期，以预测自然系统中观察到的波动。
