Dr. Joost Keuskamp is a PostDoc in the Netherlands Institute of Ecology of the Royal Academy of Sciences (NIOO-KNAW) with strong interest in coupling empirical work to modelling approaches and vice-versa. Joost has a PhD in ecology, with a focus on elemental cycling and carbon sequestration of mangrove soils in relation to microbial competition for resources. Previous work included spatial modelling of microbial nitrogen transformations at the Netherlands Environmental Assessment Agency. In his current position Joost is using meta-analyses to assess resource dependency of secondary metabolite production in algae, plants, and micro-organisms. His main research interest is how carbon sequestration and nutrient cycling in soils is determined by 1) plant-soil feedbacks and competitive interactions between decomposer micro-organisms and 2) how these interactions are modified by elemental stoichiometry of resources.
