The objective of my research program is to understand beneficial interactions between plants and microorganisms. Plant-microbe interactions are close associations or symbioses that typically benefit both the plant and the microbial partner (e.g., the plant is protected from stress - the microbe acquires nutrients in a protected habitat). Unique and specific populations of soil microorganisms influence the health, growth and competitiveness of plants in native and managed ecosystems. These specific plant-microbe associations can be utilized to benefit society in a number of ways. There is, for example, a great opportunity of using rhizobacteria, and specifically endophytic root bacteria, to enhance production of plant biomass on marginal soils (which could be used for biofuels production) or as plant-bacterial systems for remediation of environmental contaminants.

我的研究项目的目标是了解植物和微生物之间的有益互动。植物-微生物相互作用是一种密切的联合或共生关系，通常对植物和微生物伙伴都有利(例如，植物受到保护，免受胁迫--微生物在受保护的栖息地获得营养)。在本地和管理的生态系统中，独特和特定的土壤微生物种群影响植物的健康、生长和竞争力。这些特定的植物-微生物协会可以通过多种方式造福社会。例如，有很大的机会使用根际细菌，特别是内生根细菌，以提高边缘土壤(可用于生产生物燃料)上的植物生物量的生产，或用作修复环境污染物的植物-细菌系统。
