My research focuses on understanding the interactions and dynamics between crop systems and soil microbiomes in both natural and engineered systems. My overarching goal is to bridge the gap between biotechnology, agriculture, and engineering in order to understand how rhizospheres are affected by both soil chemistry and exposure to emerging contaminants of concern, with the ultimate goal of man...

Lu a Cardelli, Philippa Gardner and Giorgio Ghelli1 Abstra t. We study a spatial logi for reasoning about labelled dire ted graphs, and the appli ation of this logi to provide a query language for analysing and manipulating su h graphs. We give a graph des ription using onstru ts from pro ess algebra. We introdu e a spatial logi in order to reason lo ally about disjoint subgraphs. We extend our...
